What this MCCB carries and where it fits
The Siemens SENTRON 3VA2110-5HL36-0KL0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full -25 °C to 70 °C operating range — no derating needed up to 70 °C ambient. Its electronic trip unit adjusts between 150 A and 1200 A, covering line-feeder and distribution protection in industrial panels. Interrupting capacity is voltage-dependent: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. That 187 kA figure at 240 V gives substantial headroom for high-fault panels — useful where the available fault current approaches 200 kA.
Physical integration and auxiliary configuration
Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint for panel-mounting on a backplate or DIN rail adapter. The supplied basic switch is order code 3VA21105HL360AA0. Factory-fitted auxiliaries include 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ type), plus a shunt trip (STL) release. The trip indicator and voltage trigger are present; undervoltage release and ground-fault monitoring are not fitted. Maximum power loss is 10 W.
What the interrupting ratings mean for selectivity
The 121 kA rating at 415 V and 440 V covers most European and Asian industrial distribution panels. At 690 V the rating drops to 3.7 kA — this breaker is not intended for primary 690 V feeders with high fault current; it is a line-protection device for standard low-voltage networks.
