Auxiliary contact 1NO BCXMFE 01 (1NC) 004641501

Auxiliary contact is an element that expands the functionality of circuit breakers, allowing for status signaling or control of additional circuits. The BCXMFE 01 (1NC) model from ETI is a reliable solution for front mounting, dedicated to working with CEM9-CEM105 circuit breakers. Its construction based on screw connections ensures secure and durable electrical connections.

Functionality and application

This auxiliary contact is equipped with one normally closed contact (1NC), which means that under normal conditions the circuit is closed. A change in the state of the circuit breaker causes a change in the state of the auxiliary contact, enabling signaling or control of other devices. Thanks to this, it finds application in automation systems, lighting control, or in applications requiring remote monitoring of load status.

Characteristics and mounting

Front mounting of the BCXMFE 01 contact is simple and intuitive, which translates into time savings during installation. The rated operating current of 6A for AC-15 at 230V ensures compatibility with most standard loads. The use of screw connections guarantees the solidity and reliability of electrical connections, minimizing the risk of failure due to loose wires. Using these types of contacts allows for flexible expansion of existing installations without the need to replace entire circuit breakers.

Information about the number of normally open contacts (1), rated operating current (6A for AC-15 at 230V), type of electrical connection (screw) and mounting method (front) is important when selecting the appropriate contact for a specific application. Additionally, this contact has an ETIM EC000041 classification as an auxiliary contact block, which facilitates its identification and searching in electrical catalogs.
