Product Description

SENTRON 3VA Accessories – 3VA9157-0GK00

The Siemens 3VA9157-0GK00 is a door-mounted rotary operating mechanism (rotary handle with shaft stub) designed for the SENTRON 3VA1 MCCB (100–160 A frame class). It enables safe external operation of the circuit breaker from the panel door, allowing users to switch the MCCB ON/OFF without opening the electrical enclosure.

This accessory is part of the 8UC retrofit-compatible operating system and provides a mechanical linkage between the MCCB and the door handle, ensuring smooth and reliable operation. It is commonly used in applications where safe isolation, clear switching indication, and operator protection are required.

The 3VA9157-0GK00 supports 3-pole and 4-pole 3VA1 breakers (160 A class) and is designed for industrial switchboards where door interlocking and external switching control are essential.
