Coil Ratings
Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/−20% for AC rated current and
±15% for DC coil resistance.
2. Performance characteristic data are measured at a coil temperature of 23°C.
3. The maximum voltage is one that is applicable instantaneously to the Relay coil at 23°C and not continuously.
4. For DC-operated Relays with the LED indicator built-in, add an LED current of approx. 5 mA to the rated current.

Safety Precautions
■Safety Precautions for Correct Use
Installation
Recommend mounting MK-S Relay so that side with wiring diagram is facing down.
Handling
Check coil polarity when wiring LED Indicator and Diode Models.
Test Button
Do not use the test button for any purpose other than testing. Be sure not to touch the test button accidentally as this will turn the contacts ON.
Before using the test button, confirm that circuits, the load, and any other connected item will operate safely.
Check that the test button is released before turning ON relay circuits.
If the test button is pulled out too forcefully, it may bypass the momentary testing position and go straight into the locked position.
Use an insulated tool when you operate the test button.
Models with test buttons or LED indicators fulfill the requirements for reinforced insulation between live parts and the front of cover only when the
Relay is in a complete condition, i.e. with the nameplate, nameplate frame, test button, and slider in place. If any of these parts are removed, only
the requirements for basic insulation are fulfilled.
