This Siemens 3VA5290-6EC31-0AA0 is a molded-case circuit breaker from the 3VA series, designed for UL frame 250 applications. It offers a 3-pole configuration suitable for line protection with a rated operational current of 90A at 40°C, derating to 79.2A at 70°C. The circuit breaker provides overload protection with Ir=90A and fixed short-circuit protection with Ii ranging from 5 to 10 times the rated current.
With a maximum rated operational voltage of 690V AC and 750V DC, this breaker boasts a significant breaking capacity. According to IEC standards, it has a maximum short-circuit current (Icu) of 70kA at 415V and 10kA at 690V. Under UL 489 standards, the breaking capacity is 65kA at 480V and 25kA at 600Y/347V. The mechanical service life is typically 20,000 switching cycles, with electrical endurance varying based on voltage and load conditions.
The unit is designed for DIN rail mounting and features a lever actuator. Its dimensions are 185mm in height and 105mm in width. The overcurrent release is designated as TM230 with LI protection function. It operates within a wide temperature range, with specific current ratings provided for temperatures from 40°C to 70°C.
