Correction Factor

Ambient Temperature In Degrees Centigrade (°C)

To use this chart: Read up from the ambient

temperature to the curve, and across to find a correction

factor. Multiply the breaker rating by the correction factor

to determine the compensated rating. Calculate the

overloads in terms of the compensated rating to use the

published trip curve.

Features

• 0.5 amp to 50 amp ratings may be used as on/off switch.

• Cannot be reset against overload.

• W23 has visible trip indicator band.

• Screw termination.

• Trip-free operation.

Agency Approvals

W23 and W31 are UL 1077 Recognized as Supplementary Protectors.

File E69543, and CSA Accepted as Supplementary Protectors

(Appliance Component Protectors), File LR15734.

Users should thoroughly review the technical data before selecting a product part

number. It is recommended that users also seek out the pertinent approvals files of

the agencies/laboratories and review them to ensure the product meets the

requirements for a given application.
