The Siemens 3VA2010-5HL32-0CA0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous current across a full ambient range from -25 °C to 70 °C — no derating needed up to 70 °C, which is unusual and saves panel space. It carries a 3-pole design with an undervoltage release (UVR) built in, so it drops the load if control power fails, protecting downstream motors or conveyors from a brownout restart.
