Circuit breaker 3VA5 UL Frame 250, rated short-circuit breaking capacity class H 65kA at 480V, 4-pole, system protection TM230, FTAM, In=225A, overload protection Ir=225A fixed setting, short-circuit protection Ii=5 to 10 times In, neutral conductor protection 100% without connection. Compact circuit breaker 3VA5 for system protection, UL approval. The 3VA UL compact circuit breakers from Siemens are an essential part of the SENTRON protection components 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 the best conditions for globally exporting machines and switchgear manufacturers. Besides the IEC standard, both series 3VA5 and 3VA6 also meet the UL standard. All functionalities can thus be used and implemented worldwide for systems. This variant of the 3VA compact circuit breaker is characterized mainly 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 capacities 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 a wide range of functions. 7. Consistent accessory platform across all 3VA UL compact circuit breakers.
