Schneider Electric Auxiliary Switch - XENG

This typically describes the configuration of the contacts. '2 makers' refers to the two normally open (NO) contacts, which close (make) a circuit when activated. '1 breaker' refers to the one normally closed (NC) contact, which breaks (opens) a circuit when activated.

An auxiliary switch provides remote signaling or additional control functions related to the state of a primary device, such as a circuit breaker. It can indicate whether a breaker is open or closed, or trigger other actions based on its status.

The rated operation current (Ie) at AC-15, 230 V is 3A. This means the contacts are suitable for controlling pilot circuits, indicator lights, or low-power relays, but not high-power loads directly.

The XENG1191 features a front fastening mounting method. It is designed to be attached to the front of compatible Schneider Electric circuit breakers. Refer to the specific circuit breaker manual for detailed mounting instructions.

No, this auxiliary switch is designed for use with specific Schneider Electric circuit breakers. Compatibility must be confirmed with the circuit breaker's documentation or Schneider Electric's product specifications.

NO stands for 'Normally Open', meaning the contact is open (not conducting) when the switch is not activated. NC stands for 'Normally Closed', meaning the contact is closed (conducting) when the switch is not activated.

Verify that the auxiliary switch is correctly mounted and latched onto the circuit breaker. Ensure wiring is connected to the correct NC/NO terminals and that the circuit breaker mechanism is fully engaging the switch actuator.

Check the wiring to the NO contact and the indicator light. Confirm the light bulb is functional and that the circuit breaker is indeed in the 'on' position. Ensure the rated current of the indicator light does not exceed the switch's rating (3A at 230V AC).

Power off the circuit breaker and securely tighten the screws on the terminal connections of the auxiliary switch.
