Product Description

SENTRON 3VA Accessories – 3VA9138-0DK84

The Siemens 3VA9138-0DK84 is a front operating mechanism (flange-mounted rotary operating unit with rod system) designed for the SENTRON 3VA MCCB series. It enables safe external ON/OFF control of the circuit breaker from the panel door, improving operator safety, visibility, and ease of operation in low-voltage switchboard systems.

This accessory is engineered for 3VA5 MCCB frame applications and includes a variable depth rod mechanism (approx. 8–16 inch mounting depth) with a flanged door handle assembly. It allows the breaker to be operated without opening the panel door and ensures proper door interlocking, preventing access when the breaker is in the ON position.

The 3VA9138-0DK84 is widely used in LT panels, MCCs, PCCs, industrial switchboards, OEM control panels, and infrastructure electrical systems, where safe external operation and robust mechanical control are required.
