The Siemens SENTRON 3VA1220-5EF42-0KA0 is a 4-pole molded case circuit breaker rated 200 A continuous at 40 °C through 50 °C, with a thermal-magnetic TM240 overcurrent release and an integrated shunt trip (STL) for remote tripping. Its breaking capacity reaches 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V — figures that tell you it can interrupt high-fault currents on the line side of a distribution panel without upstream coordination issues. The shunt trip release means a control signal — from an emergency-stop button, a relay, or a PLC — can open the breaker remotely, which is standard for safety circuits and remote shutdown schemes.
Above that, it derates linearly: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C (–). The maximum power loss of 42 W is the heat the breaker dumps into the enclosure; factor that into your thermal budget.
Dimensions: 158 mm height, 140 mm width, 70 mm depth (–). The 4-pole footprint matches standard SENTRON 3VA panel cutouts; no rewiring needed if you are replacing a 4-pole 3VA frame. The supplied basic switch order code is 3VA12205EF420AA0, which is the internal switching mechanism — useful for spare-parts ordering if the breaker is ever disassembled for maintenance.
