This Siemens 3VA5270-5ED41-0AA0 is a 4-pole molded-case circuit breaker from the 3VA5 series, designed for system protection applications. It has a maximum rated operational current of 250A and a continuous operational current of 70A at 40°C, with derated values at higher temperatures.
The circuit breaker offers a breaking capacity of 35kA at 480V according to UL 489 standards and 55kA at 415V according to IEC 60947. It features a TM210 overcurrent release with LI protection function, providing overload protection at Ir=70A and fixed short-circuit protection at Ii=10 x In. The device is rated for a maximum operational voltage of 690V AC and 1000V DC, with an insulation voltage of 800V.
Designed for DIN rail mounting, this circuit breaker has a mechanical service life of typically 20,000 switching cycles. Electrical endurance is rated at 8,000 cycles at 380/415V AC and 4,000 cycles at 690V AC. It is also designated as HACR Type by UL.
Key electrical specifications include a maximum power loss of 17.1W. The overcurrent release is fixed, and the N-conductor protection is not included. This model is suitable for applications requiring robust circuit protection with reliable performance.
