Product details

The Siemens SENTRON 3VA1063-3ED36-0KC0 is a 3-pole molded case circuit breaker (MCCB) rated 63 A continuously at 40-50 °C, with a breaking capacity of 75.6 kA at 240 V AC. At 415 V the breaking capacity drops to 52.5 kA, and at 690 V to 7.5 kA; the voltage derating is steep, so verify the service voltage against the curve before specifying. For a panel running warm — say 55 °C ambient — the breaker is good for 62 A, so a BOM calling for 63 A on a 60 °C bus needs the next frame up.

Rated insulation voltage 800 V. Maximum power loss 17.3 W. This is a line-protection design (not motor-protection or generator-protection), with a shunt trip (STL) and 2 auxiliary switches HQ built in.
