UL Listed 3-Pole Configuration High Breaking Capacity (65kA) TM230 Trip Unit with FTAM Adjustable Short-Circuit Protection Robust Industrial Protection

Product description

The Siemens 3VA5212-6EC31-0AA0 is a 3-pole 3VA5 UL frame 250 circuit breaker designed for line protection with enhanced breaking capacity. It offers a breaking capacity of 65 kA at 480 V. This model utilizes the TM230 trip unit with FTAM (adjustable thermal, adjustable magnetic) protection, featuring permanently set overload protection (Ir=125 A) and short-circuit protection (Ii=5...10x In). Rated for 125A, it is supplied without connection accessories.

This circuit breaker is ideal for industrial power distribution, motor control centers, and applications requiring a higher fault current rating. It is commonly used in heavy industries, manufacturing plants, and infrastructure projects where reliability is paramount.

Stanlo Automation, a veteran-owned supplier of surplus industrial automation parts, offers the Siemens 3VA5212-6EC31-0AA0. We ensure you have access to quality components to keep your operations running efficiently, with competitive pricing and fast shipping.
