Circuit breaker 3VA5 UL Frame 400, short-circuit capacity class H 65kA at 480 V, 3-pole, system protection TM230, FTAM, In=400A, overload protection Ir=400A fixed setting, short-circuit protection Ii=5...10 x In 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 case of overload and short circuit. The 3VA UL sets standards in flexibility and modular accessory variety. The compact circuit breaker 3VA UL also offers the best conditions for machine and switchgear manufacturers exporting worldwide. In addition to the IEC standard, the 3VA5 and 3VA6 series also meet the UL standard. All functionalities can thus be used globally for systems. This variant of the 3VA compact circuit breaker is characterized primarily 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 the frame size: short-circuit 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.
