The Siemens 3VA5270-7ED36-1AA0 is a 3-pole molded-case circuit breaker from the 3VA5 series, designed for robust system protection applications. This breaker features an overload protection setting of Ir=70A and a fixed short-circuit protection setting of Ii=10 x In, with a nominal current of In=70A.
It operates at a rated voltage of 690V AC and boasts a significant breaking capacity of 100kA at 480V, and 200kA at 240V, making it suitable for high-fault current environments. The breaker is equipped with a TM210 overcurrent release and offers LI protection functions.
Designed for front connection with circular conductor terminals on both sides, it accommodates conductor cross-sections from 6 AWG to 350 kcmil. The mechanical service life is rated for a typical 20,000 switching cycles, with electrical endurance varying based on AC-1 load conditions. Its dimensions are 185mm in height, 105mm in width, and 83mm in depth, with a DIN rail mounting type.
