What the ratings mean for your panel
The Siemens 3VA1132-6EF36-0CA0 is a SENTRON molded case circuit breaker (MCCB) sized for line protection in distribution panels. Its headline number is the 220 kA interrupting capacity at 240 V — that means it can safely clear a fault current up to 220,000 A without rupturing, which is essential for high-fault service entrances or transformer-fed subpanels where available fault current is high. At 415 V it still handles 154 kA, and at 690 V it drops to 17 kA, so the voltage class of your system dictates which rating governs the installation. Rated 32 A continuous at 40 °C through 50 °C, then derates to 30 A at 70 °C. That thermal curve matters if this breaker sits in a warm enclosure — no headroom lost until above 50 °C, but above that you lose 1 A per 5 °C rise. The 13.1 W power loss at full load adds to enclosure heat, so factor it into the thermal budget if you're packing multiple breakers in a small cabinet. Three-pole construction with a TM240 thermal-magnetic overcurrent release — that's a fixed thermal trip at 32 A (the '240' refers to the frame rating in tenths of an amp, so 240 = 24 A? Actually TM240 means the thermal element is calibrated for a 32 A breaker; the TM series uses a bimetal strip for overload and a solenoid for short-circuit. The undervoltage release (UVR) is built in, so if control voltage drops below a threshold the breaker trips — common for emergency-stop circuits or undervoltage protection on motor loads.
Panel fit and mounting
Mounts on a DIN rail or directly to a backplate. Dimensions are 76.2 mm wide (3 in), 130 mm high (5.12 in), 70 mm deep (2.76 in). The 3-pole width matches standard MCCB footprints — it will drop into a slot sized for a 3-pole SENTRON or similar frame without rewiring the bus bars, as long as the mounting holes and bus spacing align. No communication module on this variant, so no extra depth for a fieldbus slice. Operating temperature range is -25 °C to 70 °C; storage from -40 °C to 80 °C. That covers most indoor panel environments. The insulation voltage is rated 800 V, so it's fine on 480/277 V or 600 V systems with margin.
