3VA5125-4ED12-0AA0

The 3VA5125-4ED12-0AA0 is a 1-pole molded case circuit breaker (MCCB) from Siemens' 3VA5 Sentron series, built on the UL Frame 125 platform for industrial and commercial power distribution. Rated for 25 at 277, it's designed as a direct upgrade path for older Siemens HED and HHED breakers, fitting Siemens P1, P2, and P3 panelboards and motor control centers. Its thermal-magnetic TM210 trip unit provides dependable overload and short-circuit protection for feeder and branch-circuit applications. Electrically, the 3VA5125-4ED12-0AA0 features fixed thermal and fixed magnetic (FTFM) trip settings, with the instantaneous trip set at 10 times the breaker's rated current for consistent short-circuit response. It carries an interrupting capacity of 25kA@277V. This combination of fixed, reliable trip settings and dependable interrupting performance makes the 3VA5125-4ED12-0AA0 well suited for industrial and commercial circuits. Mechanically, the 3VA5125-4ED12-0AA0 uses a nut-style terminal connection for line and load wiring, differing from the feed-thru or lug-style connections used on other breakers in the 3VA5 lineup. Its compact molded case keeps panel space requirements to a minimum, and its IP40-rated enclosure helps protect against dust and incidental contact. UL listed and CSA approved, the 3VA5125-4ED12-0AA0 is a dependable choice for new installations or as a replacement breaker in existing Siemens 3VA-compatible switchboards and panelboards.
