This Siemens 3VA5 series molded-case circuit breaker, part number 3VA5225-5GF41-0AA0, is a 4-pole device designed for system protection. It has a maximum rated operational current of 250A and a rated operational voltage of up to 690V AC.
The circuit breaker offers a breaking capacity of 85kA at 240V, 55kA at 415V, and 7kA at 690V according to IEC 60947 standards. Under UL 489, it provides a breaking capacity of 35kA at 480V and 18kA at 600Y/347V. The overcurrent release is of type TM240 with LI protection function, and adjustable settings for overload protection (Ir) from 175A to 250A and short-circuit protection (Ii) from 1.25 to 2.5 times the rated current.
Designed for DIN rail mounting, this circuit breaker has a mechanical service life of typically 20,000 switching cycles. It also supports 100% N-conductor protection. The insulation voltage is rated at 800V.
Key electrical specifications include a maximum power loss of 58W and an active power loss per pole of 19.33W at rated current in a hot operating state. Electrical endurance varies with voltage and load type, with 8,000 cycles at AC-1 for 380/415V and 4,000 cycles at 690V.
