Single Pole Supplementary Protectors - WMS1B, WMS1C and WMS1D Series

These are standard supplementary protectors, recognized by UL and CSA under UL 1077 and CSA 22.2. They are CE marked in accordance with Low Voltage Directive(LVD) (73/ 23/ EEC).

B Curve Trip - 3 to 5 X rate current models are suited for applications where maximum protection is required for control circuits from low level short circuit faults that could damage the wiring.

C Curve Trip - magnetic trip point is 5 to 10 times the rated current and is typically used for control circuits.

D Curve Trip - 10 to 20 X rated current models provide a magnetic range to allow for higher inrush levels during startup, that are usually seen with transformers and other high inductive systems.
