The Siemens SENTRON 3VA2110-6HN32-0BC0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient temperature range from 40 °C to 70 °C — no derating needed up to that ceiling. Breaking capacity is 242 kA at 240 VAC, 187 kA at 415/440 VAC, 121 kA at 500 VAC, and 3.7 kA at 690 VAC.
Built-in accessories for control and signaling
The auxiliary switches provide status feedback (open/closed/tripped) to a PLC or indicator lamp without needing external limit switches. Panel builders will find the depth manageable for shallow enclosures; the 86 mm dimension leaves room for cable bending radius behind the breaker.
Maximum power loss is 12.5 W at rated current. In a densely packed panel, that 12.5 W per breaker adds up — account for it in your enclosure thermal calculation, especially if multiple breakers are ganged.
