Siemens Circuit-breaker 400A 2p opt. motor-drive unit 3VA5340-0BB61-0AA0

Molded case switch 3VA5 UL frame 400 max. short-circuit rating 65kA at 480 V, 2-pole, equipment protection MCS110, In=400A without overload protection. Self-protection Ii=15 x In without connection. The 3VA5 compact circuit breaker for equipment protection has UL approval. The Siemens 3VA UL compact circuit breakers are an important component of the SENTRON protection devices for industrial applications as well as for infrastructure applications. They provide effective equipment 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 the best conditions for globally exporting machinery 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 installations. This variant of the 3VA compact circuit breaker is characterized primarily by: 1. Compact design. 2. Available as a variant for equipment protection. 3. Depending on the size: 1-, 2- (3-pole housing design) and 3-pole versions. 4. Depending on the size: switching capacity 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 various functions. 7. Consistent accessory platform across all 3VA UL compact circuit breakers.
