The TM220 thermal-magnetic release handles overload and short-circuit tripping without an external trip unit. ## Breaking capacity — the number that decides your fault level This MCCB interrupts 187 kA at 240 V AC, 121 kA at 415 V, 76 kA at 440 V, and 30 kA at 500 V. Those are the rated short-circuit breaking capacities (Icu) at each voltage. If your transformer secondary or generator bus can deliver a prospective fault current higher than the rating at your system voltage, this breaker is not the right choice — you need a higher-rated frame or a current-limiting upstream device. The 187 kA at 240 V is useful for high-fault 240 V distribution panels; at 415 V the 121 kA covers most industrial switchboards. The breaker measures 70 mm deep, 140 mm wide, and 158 mm high — a 4-pole MCCB that fits a standard panel footprint. The design of the N-conductor protection is 100 %, so the neutral pole is fully rated and trips with the phase poles — no need for a separate neutral disconnect.","metaTitle":"Siemens SENTRON 3VM1220-5GE42-0AA0 MCCB, 200 A, 4-Pole, 70 m","metaDescription":"Siemens SENTRON 3VM1220-5GE42-0AA0 molded case circuit breaker, 200 A at 40 °C, 4-pole, line protection, rated 187 kA at 240 V.
