Siemens 3VA5560-5EC32-0AA0 Molded Case Circuit Breaker

The TM230 trip unit features a fixed thermal overload (Ir) of 600A and an adjustable instantaneous magnetic trip (Ii). The magnetic pickup can be dialed from 5 to 10 times the continuous rating, giving a short-circuit trip adjustment range of 3,000A to 6,000A.

No, this breaker ships from the factory with nut keeper terminals designed for direct busbar connections or ring terminals. To terminate standard building wire, a separate mechanical lug kit such as the Siemens 3VA9673-0JJ43 (for aluminum or copper conductors) must be installed.

This 3VA55 frame circuit breaker is designed for Siemens P5 power panelboards and compatible commercial switchboards. Installing this breaker into an existing P5 provision requires a separate panelbuilder strap kit and mounting hardware to connect the nut keepers to the distribution bus.

This model is designated as Siemens Class M (Medium Low) breaking capacity. It provides fault current interruption up to 35kA at 480VAC and 18kA at 600VAC, making it suitable for standard commercial and industrial distribution limits.

This breaker is built on the Siemens 3VA55 frame, which has an 800A maximum continuous current rating. It shares the same physical footprint and internal accessory pockets as other 3VA55 and 3VA65 series breakers, which simplifies panel layouts and parts standardization.

Yes, this thermal-magnetic breaker is rated for use on direct current systems up to 500V DC, where it provides a maximum interrupting rating of 50kA. When applied on DC circuits, you must consult Siemens wiring guidelines for the proper multi-pole connection scheme based on your specific system grounding.

Yes, all Siemens 3VA5 molded case circuit breakers equipped with thermal-magnetic trip units are UL listed for reverse feed applications. This allows the breaker to be safely back-fed without impacting its protective characteristics or interrupting ratings.
