1NO contact block MCB-10 1SFA611610R1001

### Auxiliary contact block – expand the possibilities of your installation

This 1NO contact block, catalog number 1SFA611610R1001, is an element that allows you to add an additional contact to existing automation and protection devices. Designed for front mounting, it offers flexibility in building control and signaling circuits. This solution will find application in both new installations and in the modernization of existing systems.

Construction and practical application

The MCB-10 block is characterized by a single normally open contact (1NO), which means that the circuit is open at rest and closes after a control signal is activated. Made with attention to detail, it ensures reliable operation for a long time. Mounting is done from above, which makes installation easier and faster. Electrical connections are made with screws, which guarantees a secure and durable connection of the wires.

Thanks to this contact block, it is easy to implement functions of device status signaling, remote control or switching of auxiliary circuits. It will work in motor control circuits, building automation systems or when expanding existing electrical panels. The rated operating current of 6A for AC-15 at 230V allows for use in various applications.

Key features and benefits

• Versatility: Compatible with a wide range of ABB modular devices, it allows you to expand existing installations without having to replace the entire system.
• Simple installation: Front mounting and screw connections greatly facilitate and speed up the installation process – saving time for both the installer and the end user.
• Reliability: Solid construction guarantees long-lasting and trouble-free operation in various environmental conditions.
• Compact dimensions: Minimal dimensions allow you to save space inside electrical panels, which is especially important in limited spaces.
• Flexibility: A single normally open contact (1NO) allows you to implement various control and signaling functions depending on the user's needs.
