This Siemens 3VA5140-5EC31-0AA0 is a 3-pole molded-case circuit breaker from the 3VA5 series, designed for line protection. It features a rated operational current of 40A at 40°C and a maximum operational voltage of 690V AC (50/60Hz) or 500V DC. The circuit breaker has a breaking capacity of 35kA at 480V according to UL 489 standards and 55kA at 415V according to IEC 60947.
Key electrical characteristics include overload protection set at Ir=40A and fixed short-circuit protection adjustable from 5 to 10 times the rated current (Ii=5...10 x In). The overcurrent release type is TM230 with LI protection function. It is also designated as HACR Type, suitable for Heating, Air Conditioning, and Refrigeration applications.
With a mechanical service life of typically 15,000 switching cycles and electrical endurance ratings of up to 8,000 cycles at 380/415V, this circuit breaker is built for durability. It is designed for DIN rail mounting and has dimensions of 140mm height, 76.2mm width, and 76.2mm depth.
