Siemens Circuit-breaker 450A 2p opt.motorantr 3VA5445-6EC61-0AA0

Circuit breaker 3VA5 UL frame 600, short-circuit current rating class H 65kA @ 480 V, 2-pole, system protection TM230, FTAM, In=450A, overload protection Ir=450A fixed setting, short-circuit protection Ii=5...10 x In without connection. The 3VA compact circuit breaker for system protection is UL approved. Siemens' 3VA UL compact circuit breakers are an essential part of the SENTRON protection components for industrial applications as well as for infrastructure applications. They provide effective equipment 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 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 size: 1-, 2- (3-pole housing design) and 3-pole versions. 4. Depending on the size: breaking capacity from 25kA to 100 kA at 480 V for 3-pole breakers and 25 kA to 50 kA 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.
