Circuit breaker 3VA5 UL Frame 250, switching capacity class M 35kA @ 480V, 4-pole, system protection TM240, ATAM, In=150A, overload protection Ir=120A...150A, short-circuit protection Ii=5...10 x In, neutral conductor unprotected without connection. Compact circuit breaker 3VA5 for system protection, UL approval. The 3VA UL compact circuit breakers from Siemens are an essential component of the SENTRON protection devices for industrial applications as well as for infrastructure applications. They provide effective system and starter protection through safe disconnection in the event of overload and short circuit. The 3VA UL sets standards in flexibility and modular accessory variety. Additionally, the 3VA UL compact circuit breaker offers optimal conditions for globally exporting machines and switchgear manufacturers. Besides the IEC standard, the two series 3VA5 and 3VA6 also meet the UL standard. All functionalities can thus be used worldwide for systems. This variant of the 3VA compact circuit breaker is particularly characterized by: 1. Compact design. 2. Available as a variant for system protection. 3. Depending on the frame size: 1-, 2- (3-pole housing design) and 3-pole versions. 4. Depending on frame size: switching capacities from 25kA to 100kA at 480 V for 3-pole breakers and 25kA to 50kA at 277 V for 1-pole breakers. 5. The series features a thermal-magnetic overload relay. 6. Modular and easy-to-install internal accessories with a variety of functions. 7. Consistent accessory platform across all 3VA UL compact circuit breakers.
