The Siemens 3VA5170-4EC31-0AA0 is a robust molded case circuit breaker (MCCB) engineered for commercial and industrial power distribution systems. Built on the compact 3VA51 frame, this 3-pole, 70A breaker provides dependable overload and short-circuit protection through its TM230 thermal-magnetic trip unit. Featuring fixed thermal protection and adjustable magnetic protection, it allows for improved coordination with downstream devices while maintaining reliable fault-clearing performance. Designed for installation in Siemens P1, P2, and P3 panelboards, SB switchboards, and motor control centers, it serves as a direct replacement for legacy ED63B070 circuit breakers. Its current-limiting design, HACR rating, and reverse-feed capability make it an excellent choice for demanding electrical applications.
