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.","metaTitle":"Siemens 3VA1220-5EF42-0KA0 SENTRON MCCB, 200 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA1220-5EF42-0KA0 molded case circuit breaker, 200 A rated current, 4 poles, breaking capacity 187 kA at 240 V.
