3VA9158-0VK20 SIEMENS

The 3VA9158-0VK20 is a rear interlock mounting plate accessory designed specifically for use with the 3VA1 160 series of molded case circuit breakers (MCCBs) from Siemens. This accessory facilitates the creation of mechanically interlocked circuit breaker systems, enhancing safety and operational reliability. Mechanical interlocking prevents the simultaneous closure of two or more circuit breakers, ensuring that only one breaker can be active at any given time. This is crucial in applications where parallel power sources or redundant systems are employed. The mounting plate provides a secure and stable platform for the interlock mechanism. It ensures precise alignment and reliable operation of the interlock. The robust construction of the plate guarantees durability and long-term performance in demanding industrial environments. Installation is straightforward, minimizing downtime and simplifying the integration of the interlock system. By preventing conflicting power sources, the 3VA9158-0VK20 contributes to the overall safety and efficiency of electrical distribution systems.
