This Siemens 3VA5190-4EC31-1AA0 is a molded-case circuit breaker from the 3VA5 series, designed for system protection applications. It features a 3-pole configuration and a rated operational current of 90A at 40°C, with a maximum frame size of 125A. The circuit breaker offers a breaking capacity of 25kA at 480V and a voltage rating of 690V.
Key electrical protection functions include overload protection set at 90A and fixed short-circuit protection adjustable from 5 to 10 times the rated current (In). The overcurrent release type is TM230, with LI protection function. It has a mechanical service life of typically 15,000 switching cycles and electrical endurance ratings varying by voltage level, up to 8,000 cycles at 480V.
The unit has a compact mechanical design with dimensions of 140mm height, 76.2mm width, and 76.5mm depth. It is rated IP40 on the front and operates within an ambient temperature range of -25°C to 50°C. Mounting is via DIN rail. The circuit breaker is also HACR Type approved and can optionally be fitted with a motor drive.
