The TM220 release means the thermal-magnetic trip is fixed at 200 A (the '220' code), so there's no adjustment dial; it's sized for a specific feeder or main. Breaking capacity hits 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V — figures that cover most low-voltage distribution fault levels in North American and IEC installations. At 690 V it still interrupts 11.9 kA, which matters for industrial systems with step-up transformers or VFD line reactors. At 45 °C the breaker still holds 200 A; at 55 °C it derates to 194 A, at 65 °C to 182 A, and at 70 °C to 176 A. ## What it protects and how it trips Designed for line protection — feeder or main breaker duty in distribution panels. The TM220 release combines a thermal bimetal for overload (inverse-time, slow enough to start motors) and a magnetic coil for short-circuit (instantaneous above the magnetic pickup).","metaTitle":"Siemens 3VA1220-4GE42-0AA0 SENTRON MCCB, 200 A, 4-Pole, TM22","metaDescription":"Siemens 3VA1220-4GE42-0AA0 SENTRON molded case circuit breaker, 200 A rated, 4-pole, TM220 release, 121 kA at 240 V.
