The Siemens 3VA5270-6EF36-0AA0 is a 3-pole molded-case circuit breaker from the 3VA5 series, designed for system protection applications. It features a rated operational current of 70A at 40°C, with derating at higher temperatures. The breaker provides a robust breaking capacity, including 65kA at 480V and 100kA at 240V, according to UL 489 standards.
With a rated insulation voltage of 800V and an operating voltage of up to 690V AC, this circuit breaker is suitable for various industrial and commercial power distribution systems. It incorporates TM240 overcurrent release with LI protection function, offering adjustable overload protection from 56A to 70A and short-circuit protection from 5 to 10 times the nominal current.
The unit is designed for DIN rail mounting and has mechanical dimensions of 185mm height, 105mm width, and 83mm depth. It also meets HACR Type requirements per UL 489. The breaker has a typical mechanical service life of 20,000 switching cycles and electrical endurance ratings that vary with voltage and load conditions.
