The Siemens SENTRON 3VA1132-3EF36-0AB0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying 32 A continuously at 40 °C with a TM240 thermal-magnetic release. Its interrupting capacity hits 75.6 kA at 240 V, dropping to 52.5 kA at 415 V and 32 kA at 440 V — numbers that matter when you're coordinating downstream branch protection and need the SCCR to hold under fault. Max power loss is 10.6 W, which is manageable for enclosure thermal budgeting.
The 32 A rating holds across ambient temperatures from 40 °C through 50 °C without derating; at 55 °C it drops to 31 A, and at 70 °C to 30 A. That's a standard line-protection characteristic, not a motor-protection curve. The 75.6 kA interrupting rating at 240 V gives solid selectivity headroom for a 22 kA or 25 kA available fault current at the panelboard; at 480 V the 52.5 kA still covers most industrial services.
Panel integration
The 130 mm height clears most enclosure gutters. Two auxiliary switches (HP design) are built in, so you can wire status feedback without an add-on module.
