The Siemens SENTRON 3VA1010-4ED32-0JA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current (Iu) at 40 °C through 50 °C, with a TM210 thermal-magnetic overcurrent release. Its interrupting capacity reaches 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V — figures that govern selectivity coordination downstream. The integrated shunt trip (STL) release (order code 3VA9688-0BL32 for the auxiliary trip unit) allows remote tripping via a control signal, so this breaker fits into a safety circuit that needs a hard-wired trip path independent of the overcurrent protection.
Sizing and thermal derating for panel builders
Above that, derate linearly: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, 90 A at 70 °C. The TM210 release is fixed thermal-magnetic — no electronic adjustment, so the trip curve is set at the factory.
The breaker includes a voltage trip trigger but no undervoltage release, no auxiliary contact version, no communication function, no phase failure detection, and no ground fault monitoring.
