Siemens 3VA4190-4ED34-0AA0 U AC Motor Soft Starter

Siemens 3VA4190-4ED34-0AA0 is a Sentron molded‑case circuit breaker (MCCB) designed for 3‑phase AC power distribution. This 3‑pole device is rated for 90 A nominal current (In = 90 A) with a short‑circuit breaking capacity of 25 kA at 480 V, and it uses a fixed thermal‑magnetic (FTFM) trip unit for reliable overload and fault protection. Built on the UL 125 frame size, it supports load‑side lug terminals for secure, code‑compliant connections in switchgear and control panels. The 3VA4190‑4ED34‑0AA0 variant is used to protect motors and other loads within industrial electrical installations, providing coordinated protection with upstream devices and predictable interruption during fault conditions.
