Line protection breaker with headroom to spare
The Siemens SENTRON 3VM1220-4GD42-0AA0 is a 4-pole molded case circuit breaker rated for line protection duty, carrying 200 A continuously at 40 °C through a TM210 thermal-magnetic release.
Breaking capacity that follows the voltage
This breaker delivers 121 kA at 240 V, 76 kA at 415 V, 53 kA at 440 V, and 17 kA at 500 V.
Front IP40 protection keeps out tools and fingers; the interior is not sealed against washdown, so mount it in a clean dry location or behind a gland plate. Maximum power dissipation is 42 W at full load — account for that heat in the enclosure thermal budget.
