Siemens 3VA4190-6ED34-0AA0 Molded Case Circuit Breaker

Siemens 3VA4190-6ED34-0AA0 is a three-pole molded-case circuit breaker in the Siemens 3VA4 family, designed for distribution panels and MCCs requiring robust overcurrent protection. It delivers 90 A (In) of rated current and uses a fixed thermal-magnetic trip unit (TM210, FTFM) for reliable protection against overloads and short circuits. Termination is via lug connections (LD/LUG) for straightforward wiring. The device is rated for up to 690 V AC operation and provides a short-circuit breaking capacity of 65 kA at 480 V, making it suitable for moderate‑voltage feeders. Weight is about 0.743 kg, and the unit supports a mechanical life of around 15,000 switching cycles with electrical endurance of 8,000 cycles at 480 V (4,000 at 600 V). The short‑circuit protection rating (Ii) is 10 × In (900 A) for this fixed-trip design, and the breaker is UL 489 listed for use in appropriate U.S. electrical systems. This model designation confirms a 3-pole, 90 A breaker in a 3VA4 frame, intended as a direct replacement in Siemens panels and compatible enclosures that support 3VA4 MCCBs.
