The interrupting capacity of 76 kA at 240 V and 53 kA at 415 V tells you the maximum fault current it can safely clear at those voltages; for 500 V systems the rating drops to 12 kA. The TM220 overcurrent release is a thermal-magnetic design — thermal for overload protection, magnetic for short-circuit — with no electronic trip unit, so no adjustable curves or communication. The 3-pole configuration covers three-phase loads. IP40 on the front means protection against tools and small wires entering the front face, but not against water — keep it inside a dry enclosure. ## Where this MCCB fits in a panel No undervoltage release, no shunt trip, no ground-fault monitoring: it's a bare line-protection breaker with no accessories. If your circuit needs undervoltage protection or remote tripping, you'll need to add an external module or choose a different variant.","metaTitle":"Siemens 3VM1225-3EE32-0AA0 SENTRON MCCB, 250 A, 3-Pole, TM22","metaDescription":"Siemens 3VM1225-3EE32-0AA0 SENTRON molded case circuit breaker, 250 A at 40 °C, 3-pole, TM220 thermal-magnetic release, 76 kA at 240 V.
