Circuit breaker 3VA5 UL Frame 125 Switching capacity class S 25kA @ 480V 4-pole, system protection TM230, FTAM, In=25A overload protection Ir=25A fixed setting short-circuit protection Ii=6...12 x In N-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 overload and short-circuit situations. The 3VA UL sets standards in flexibility and modular accessory variety. Additionally, the 3VA UL compact circuit breaker offers excellent conditions for globally exporting machines and switchgear manufacturers. Besides complying with the IEC standard, both 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 distinguished 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 frame size: switching capacities of 25kA, 100kA at 480V for 3-pole breakers and 25kA, 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 a variety of functions. 7. Consistent accessory platform across all 3VA UL compact circuit breakers.
