What this MCCB delivers
The Siemens SENTRON 3VA1132-5EF36-0CC0 is a 3-pole molded case circuit breaker rated for line protection, with a rated continuous current Iu of 32 A that holds flat across 40 °C to 50 °C before a gentle thermal derating curve — at 70 °C it still carries 28.8 A. The interrupting capacity is the headline: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. That kind of fault-clearing muscle means it can sit at the main distribution point in a high-fault industrial panel without needing upstream fuses to back it up. The overcurrent release is a TM240 thermal-magnetic unit, and it ships with an undervoltage release (UVR) plus two HQ auxiliary switches. No communication function, no phase-failure detection — this is a straightforward, high-interrupting MCCB for a main feeder or large branch.
Panel fit and integration
The 3VA1132-5EF36-0CC0 measures 76.2 mm wide, 130 mm high, and 70 mm deep — a standard SENTRON 3VA frame size that drops into a DIN-rail or screw-mounted panel cutout. Front IP40 protection keeps dust out of the enclosure; the terminals accept copper or aluminum conductors up to the rated cross-section. The integrated undervoltage release (UVR) and the two HQ auxiliary switches (order code 3VA9608-0BB24 for the auxiliary trip block) are factory-fitted, so no field wiring of add-on modules.
