The Siemens 3VA1132-3EF36-0CA0 is a SENTRON molded case circuit breaker (MCCB) rated for 32 A continuous current at 40 °C, with a 3-pole configuration and a TM240 thermal-magnetic overcurrent release. The front face carries an IP40 rating, acceptable for enclosed distribution boards but not for washdown zones.
This MCCB interrupts 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. Those are the rated ultimate short-circuit breaking capacities (Icu) per IEC 60947-2. For a 415 V distribution panel, 52.5 kA covers most industrial service-entrance and sub-feed applications; at 690 V the 10.5 kA figure still handles motor branch circuits with moderate fault current. The 32 A continuous rating holds steady up to 50 °C ambient, then derates to 30.72 A at 55 °C and 28.8 A at 70 °C — a factor to check if the breaker sits near transformers or drives inside a warm enclosure.
