What is the part number for the SDE contact for a Masterpact NT or NW.


30 September 2021

The SDE contact is fitted as a standard on the Masterpact NT or NW circuit breaker.

An optional second SDE contact can be fitted to the circuit breaker if it's specified at the time of ordering.

A second SDE contact can be fitted to an existing Masterpact NT or NW by contacting the Schneider Electric service department. This is necessary, as the Micrologic has to be dismantled.

Note: "SDE" is a French Acronym and stands for "Signal Défaut Electrique" the English translation is "Electrical fault signal"
