The Siemens SENTRON 3VA2110-5HL32-0KL0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current, with an adjustable overload trip range from 150 A to 1200 A. It's designed for line protection in distribution panels and motor control centers.
Interrupting capacity and thermal performance
This MCCB delivers an interrupting capacity of 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — covering most industrial service voltages without needing a current-limiting upstream breaker. The thermal rating holds steady at 100 A across the full ambient range from 40 °C to 70 °C, so no derating curve to worry about in a warm panel.
Physical fit and mounting
At 86 mm deep, 105 mm wide, and 181 mm tall, it fits a standard MCCB cutout in a distribution panel or motor control center. The 105 mm width is typical for a 3-pole frame in this class — check your bus-bar spacing if replacing an older narrow-frame breaker.
Auxiliary and release options
Factory-fitted with 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ type), plus a shunt trip (STL) release for remote tripping. No undervoltage release or ground-fault monitoring on this variant — those are separate order codes if your spec requires them.
Environmental limits and power loss
Operates from -25 °C to 70 °C, stores from -40 °C to 80 °C. Max power dissipation is 10 W — negligible for panel thermal calculations but worth noting if you're packing multiple breakers in a sealed enclosure.
