Snapak(R) Series Magnetic Circuit Protectors Introduction * 55 Handles * 56 Configurations * 61 Operating Characteristics * 63 Delay Curves * 64 Specifications * 65 Hardware * 66 Decision Tables * 67 T/R/PP/PR/CR/CPP/CPR Series Hydraulic Magnetic Circuit Protectors (SNAPAK(R)) INTRODUCTION The AirpaxTM SNAPAK(R) series is a snap-acting hydraulicmagnetic circuit protector that combines power switching and accurate, reliable circuit protection in one aesthetically pleasing package. The SNAPAK(R) combines the functions of three separate components: power switch, fuse and fuse holder. To the OEM, this means that only one item has to be mounted instead of three. Less assembly is required, inventory is cut by twothirds and greater panel density is obtainable with less clutter. In addition, the SNAPAK(R) can be operated at either DC or 50/60Hz, eliminating the need to specify, order and stock separate units. 400Hz units are also available. Since the SNAPAK(R) is snap-acting, it assures immediate opening and closing of the contacts. Its design also prevents operator "teasing" of the contacts and minimizes arcing. SNAPAK(R) circuit protectors are UL Recognized as supplementary protectors per UL STD. 1077, CSA Certified as supplementary protectors per CSA STD. C22.2 No. 235, TUV Approved as circuit breakers for equipment per STD. EN 60934, CCC Approved (customer must request product be manufactured in China) and CE Compliant. In addition, most versions are certified by UL to meet spacing requirements of IEC 950 for basic and functional insulation for front panel mounting. To enhance front-panel aesthetics, SNAPAK(R) is offered with paddle and rocker handles in six attractive colors and push-pull and push-to-reset actuators. Also offered is a variety of optional mounting hardware. The push-pull version is supplied with a black button with a white indicating band. Consult factory for details and exceptions. Typical applications include office appliances, electronic data processing, medical equipment, business machines, vending and amusement machines. Push-pull versions are particularly well suited for medical instrumentation, automotive production transfer lines and other applications where accidental turn off is unacceptable. For those applications which do not require circuit protection, SNAPAK(R) is offered in a power-switch-only configuration. Orientation of the button when marked with an amperage notation must be specified when using the fourth decision table. Push-to-reset is supplied with a contrasting color indicating shaft. In addition, SNAPAK(R) is offered in SPST and DPST configurations. The single pole satisfies most applications. The two-pole version is often used for extra safety in products that utilize high voltage or where current sensing and breaking of both sides of the line is required. Quick connect terminals are standard, UNC 8-32 or M4 screw terminals are available as additional termination options. 55 SNAPAK(R) Series - Introduction http://airpax.sensata.com SNAPAK(R) (T/R/PP/PR CR/CPP/CPR) Mounting Details with Locking Ring .500 .010 .000 .355 [12.70 .025 ] [9.02] .000 .125 [3.18] TOGGLE ACTUATORS without Locking Ring The SNAPAK(R) is available with paddle handles in six attractive colors.

In addition to providing conventional overcurrent protection, it is simultaneously used as an on-off switch. Series Trip Single Pole Two Pole LOAD 2 1 LINE LINE Shunt Trip Single Pole Shunt Trip The shunt trip is designed for controlling two separate loads with one assembly. The control is established by providing overload protection for the critical load. When the current through this load becomes excessive and reaches the trip point, the protector will open and remove power from both loads simultaneously. The current rating of both loads must not exceed the maximum contact rating. 1 LINE LINE 3 SHUNT 4 2 LOAD LINE 1 LINE LINE 3 WHITE LEAD 7.00 0.50 [177.8 12.7] [177.8 12.7] LOAD COIL LOAD SHUNT LOAD WHITE LEAD 7.00 0.50 2 LINE Two Pole ( 1 pole shunt) Relay Trip (Note A) Single Pole Relay Trip This permits the overload sensing coil to be placed in a circuit which is electrically isolated from the contacts. The coil may be actuated by sensors monitoring pressure, flow, temperature, speed, etc. Other typical applications include crowbar, interlock and emergency/rapid shutdown circuitry. Trip may be accomplished by voltage or current, which must be removed after trip.

SNAPAK(R) Series - Configurations 62 OPERATING CHARACTERISTICS Inrush Pulse Tolerance Many circuit protector applications involve a transformer turn-on, an incandescent lamp load, or a capacitor charge from a DC source. Each of these applications has one common factor: a steep transient of very high current amplitude and short duration. This takes the form of a spike or a single pulse and is the cause of most nuisance tripping associated with magnetic circuit breakers. MAXIMUM DCR AND IMPEDANCE Current Ratings (Amps) SNAPAK will withstand, without tripping, a single pulse of 8 milli-seconds duration (half sine wave configuration) and peak amplitude of 9 times its rating without the inertia wheel and 13 times its rating with an inertia wheel.

Endurance Mechanical life in excess of 50,000 operations. In many applications, however, contact wear due to the electrical load determines unit life. At maximum electrical ratings, the SNAPAK(R) can perform 10,000 operations at rated current and voltage. Under UL 1077, the SNAPAK(R) can perform 50 operations at 150% of maximum rated current followed by 6,000 operations at maximum rated current. Under EN60934 the SNAPAK(R) can perform 6,000 electrical operations. After any endurance cycle, the breaker will calibrate and have working dielectric strength. 10000 TIME IN SECONDS Trip Free Will trip open on overload, even when forcibly held on.This prevents operator from damaging the circuit by holding handle in the ON position. Trip Indication The operating handle moves forcibly and positively to the OFF position on overload.

SNAPAK(R) Series - Hardware 66 HOW TO ORDER The ordering code for the SNAPAK(R) circuit protectors may be determined by following the steps in the decision tables shown here. The coding given permits a self-assigning part number, with certain limitations (due to the adaptability of magnetic protectors to complex circuits), requires a factory-assigned part number. 1 First Decision Handle The example shown is the code for a paddle handle, single pole (UL construction), series circuit protector designed for operation of a 50/60Hz/ DC circuit. A slow time delay and rating of 5 amperes has been indicated. Handle color is black, and a bright nickel knurled nut, vertical mount (ON-OFF) indicator plate and locking ring are to be supplied. To determine the ordering code for your particular SNAPAK(R) unit, simply follow the steps shown, then fill in the letters and/ or numbers in the boxes. Space is available on the circuit breaker label for your part number (up to 12 digits). You may then use your own part number to place an order or as a reference for further questions you may have. This option does require a factory assigned part number for traceability to your drawing or internal part number.

CWhen ordering Paddle Handles, you may choose one item from each hardware group to add to 5th decision if such items are desired. For example, "-11ALCA" would indicate a bright nickel knurled nut, plus a vertical mount indicator, plus a locking ring, plus #8-32 screw terminal, straight with tabs. BA n LED with 750 ft. L @ 20mA is provided in the center of the handle. Maximum power dissipation @ 25C is 135mW. Continuous forward current is 20mA. Forward voltage, typical, is 1.6v at 20mA. Reverse current, typical, is 100mA @ 3.0 volts. An external resistor may be required to limit current to these values. DAll units except Rocker units will have (1) hex nut installed as standard hardware for the back of a panel. The choices in the fifth decision table are intended for the front or visible side of the panel and are offered for Paddle Handle configuration only. Push-Pull and Push-to-Reset configurations include one (1) panel nut and one (1) hex nut as standard hardware. E Switch only -- no current overload protection provided. 67 SNAPAK(R) Series - Decision Tables F.
