Siemens 3VA5215-5EC31-0AA0 Molded Case Circuit Breaker

It is designed for Siemens 3VA panelboards and switchboards. As part of the 3VA52 frame group, it fits mounting provisions specifically dimensioned for Siemens 250A maximum frame breakers.

The breaker utilizes a TM230 thermal-magnetic trip unit. The thermal overload (long-time) continuous current is fixed at 150A, while the magnetic (instantaneous) short-circuit pickup is adjustable, allowing you to fine-tune the tripping threshold for fault currents.

Yes. All Siemens 3VA5 thermal-magnetic circuit breakers are UL listed for reverse feed applications, providing flexibility for wiring orientation during installation.

The 0AA0 suffix indicates the breaker is shipped from the factory without wire lugs. It features a punched copper connection bar. If you intend to terminate standard wire instead of bus, you must source field-installable lug kits separately.

This breaker is rated for DC applications up to 500VDC with a 50kA interrupting capacity. When applying this 3-pole breaker on 500V DC networks, standard practice requires wiring all three poles in series.

The 3VA5215-5EC31-0AA0 is built on the Siemens 3VA52 frame, which has a maximum continuous current capacity of 250A.

This breaker is equipped with LI protection functions. The L stands for Long-Time delay, which safely protects the circuit against sustained thermal overloads. The I stands for Instantaneous, which immediately trips the breaker during a high-level short-circuit fault to prevent equipment damage.

Yes. The 3VA5 platform accepts a variety of standardized, modular internal accessories including auxiliary switches, alarm switches, shunt trips, and undervoltage releases that fit directly inside the breaker housing.
