Auxiliary contacts for circuit breakers – expanding the functionality of the installation

The STYK-PS-350 auxiliary contacts from Legrand are a reliable element that expands the capabilities of circuit breakers from the S300, S310 and P300 series. They enable the implementation of additional functions in control and signaling circuits, increasing the flexibility and functionality of the electrical installation. Mounted on the left side of the circuit breaker, they provide convenience and ease of integration.

Versatility and compatibility

These contacts are compatible with a wide range of Legrand circuit breakers, including S300, S310, P312, P314, P344 and FRX300. This makes them a universal solution for many applications – both in home and industrial installations. Compatibility with DX-IS further expands their scope of application.

Parameters and user features

The PS-350 auxiliary contact is characterized by a rated current of up to 5A at a voltage of 250V AC (AC-15 operating category). Its compact design – a width of only 0.5 module (17.5 mm) – allows for efficient use of space in the switchboard. It has one changeover contact, which enables the implementation of various control and signaling functions. The rated switching current is 6A, and the maximum current of the main contacts is 125A. The rated voltage is 240V. Universal mounting capability makes adaptation to specific needs simple and intuitive.
