The Siemens 3VA5290-5EC31-0AA0 is a 3-pole molded-case circuit breaker from the SENTRON series, designed for system protection applications. It features a rated operational current of 90A, with a maximum rated operational voltage of 690V AC and 750V DC. The breaker has a breaking capacity of 35kA at 480V according to UL 489 standards and 55kA at 415V according to IEC 60947 standards.
This circuit breaker utilizes a TM230 overcurrent release with LI protection function. It has a mechanical service life of typically 20,000 switching cycles and electrical endurance ratings of 8,000 cycles at 380/415V and 4,000 cycles at 690V. The dimensions are 7.3 inches (185 mm) in height, 4.1 inches (105 mm) in width, and 3.3 inches (83 mm) in depth. It is designed for DIN rail mounting.
Key electrical specifications include an insulation voltage of 800V and a maximum power loss of 24.6W. The adjustable short-circuit protection ranges from 5 to 10 times the rated current (In=90A), with an adjustable response value for li from 450A to 900A. The breaker is marked according to UL 489 and is suitable for HACR Type applications.
