Product Description

SENTRON 3VA Accessories – 3VA9137-0EK11

The Siemens 3VA9137-0EK11 is a front mounted rotary operating mechanism (door-coupled handle accessory) designed for the SENTRON 3VA MCCB series. It enables safe external ON/OFF operation of the circuit breaker directly from the panel door, improving operator safety, convenience, and visibility of breaker status in low-voltage switchboard systems.

This accessory is typically used with 3VA5 MCCB (around 125A frame class) and allows the breaker to be operated without opening the panel door. It also provides door interlocking functionality, ensuring the panel door cannot be opened while the breaker is in ON position, enhancing electrical safety during maintenance and operation.

The 3VA9137-0EK11 is widely used in LT panels, MCCs, PCCs, industrial distribution boards, OEM switchboards, and infrastructure electrical systems, where safe external operation and mechanical interlocking are required.
