Contact block 1NC MCB-01 1SFA611610R1010

Auxiliary contact block – expanding the functionality of circuit breakers

The MCB-01 contact block is an additional element that expands the capabilities of standard overcurrent circuit breakers. It allows adding an additional auxiliary circuit, which can be used to signal the status of the circuit breaker or control other devices. Installation is simple and intuitive, which translates into time savings for both the installer and the end user.

Characteristics and application

The MCB-01 contact block is mounted from above, directly onto the circuit breaker. The front mounting method ensures a stable connection and easy access for servicing if needed. It uses screw connections, which guarantee a secure and durable connection of the wires. Designed to operate with a rated current of 6A for AC-15 at a voltage of 230V, making it an ideal solution for control and signaling circuits.

Advantages and benefits

• Expanded functionality: Adds the ability to signal the status of the circuit breaker or control other devices without the need for additional relays.
• Simple installation: Top mounting and front installation method facilitate and speed up installation work.
• Secure connections: Screw connections ensure a secure and durable connection of the wires, minimizing the risk of failure.
• Compliance with standards: The contact block has been designed with safety and reliability in mind, meeting applicable industry standards.
• Versatility: Can be used in various applications where additional control or signaling of the circuit status is required.
• Compact dimensions: Allow installation in tight switchgear spaces.

The MCB-01 contact block has one normally open contact (1NO) and no normally closed (0NC) or changeover (0) contacts. This configuration is ideal for applications where a single signal confirming the status of the circuit breaker or activating another device after it is switched on is needed.
