This Siemens 3VA5212-5EF32-2AA0 is a 3-pole molded case circuit breaker from the 3VA5 UL Frame 250 series. It is designed for line protection with an operational current of 125A at 40°C and a rated operating voltage of up to 690V AC.
The circuit breaker features a breaking capacity of 35kA at 480V and 55kA at 415V, with a switching capacity class of M according to IEC 60947. The overcurrent release is a TM240 with LI protection function, adjustable from 100A to 125A for overload (Ir) and 625A to 1250A for short circuit (Ii).
It is suitable for HACR type applications and is mounted on a DIN rail. The mechanical service life is rated for 20,000 cycles, with electrical endurance varying by voltage and load conditions. Key electrical specifications include an insulation voltage of 800V and a maximum power loss of 23W.
Compliance includes UL approval. The RoHS status is RoHS3 Compliant, MSL is 1, and REACH status is Unaffected, though these are treated with low confidence due to lack of verification.
