This Siemens 3VA6340-5JP31-0AA0 is a 3-pole molded-case circuit breaker from the 3VA6 series, designed for system protection. It has a nominal current rating of 400A and a breaking capacity of 35kA at 480V, with higher capacities at lower voltages according to UL 489 standards.
The circuit breaker utilizes an ETU550 electronic trip unit with LSI (Long-time, Short-time, Instantaneous) protection functions. Overload protection is adjustable from 160A to 400A, while short-circuit protection settings include Isd from 0.6 to 10 times the rated current and Ii from 1.5 to 10 times the rated current. It operates with a maximum insulation voltage of 600V and a rated voltage of 690V.
With a mechanical service life of 15,000 cycles and electrical endurance ratings of up to 6,000 cycles at 480V, this breaker is built for durability. It features a communication function for system integration. The unit is designed for DIN rail mounting and has dimensions of 248mm height, 138mm width, and 110mm depth.
