The Siemens SENTRON 3VA2110-6HL32-0JC0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C, designed for line protection in distribution panels and industrial switchboards. It carries a 242 kA interrupting capacity at 240 V, dropping to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V — the high short-circuit rating at low voltage makes it suitable for high-fault service-entrance or main-breaker positions where available fault current is substantial.
The breaker measures 105 mm wide, 181 mm high, and 86 mm deep — a standard MCCB footprint that fits most 3-pole panelboard and switchboard mounting patterns without modification. It dissipates a maximum of 10 W at rated load, so thermal management inside a sealed enclosure is straightforward — no forced cooling required for most installations.
Environmental and operating range
Rated for continuous operation from -25 °C to 70 °C ambient, and can be stored from -40 °C to 80 °C. The 100 A rating holds flat across the entire 40 °C to 70 °C operating range — no derating needed up to 70 °C.
