Circuit breaker 3VA5 UL Frame 125, short-circuit current rating class H 65kA @ 480V, 4-pole, system protection TM230, FTAM, In=45A, overload protection Ir=45A fixed setting, short-circuit protection Ii=5...10 x In, neutral conductor unprotected without connection. The compact circuit breaker 3VA5 for system protection has UL approval. The compact circuit breakers 3VA UL 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 circuits. The 3VA UL sets standards in flexibility and modular accessory variety. Furthermore, the compact circuit breaker 3VA UL offers the best conditions for machine and switchgear manufacturers exporting worldwide. In addition to the IEC standard, both series 3VA5 and 3VA6 also meet the UL standard. All functionalities can thus be used globally for systems. This variant of the compact circuit breaker 3VA 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: breaking capacity from 25kA to 100kA at 480V for 3-pole breakers and 25kA to 50kA at 277V for 1-pole breakers. 5. The series features a thermal-magnetic overload relay. 6. Modular and easy-to-install internal accessories with diverse functions. 7. Consistent accessory platform across all compact circuit breakers 3VA UL.
