MCCB for line protection with shunt trip
The SENTRON 3VA2110-5HN36-0KA0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current, designed for line protection in distribution panels. Its interrupting capacity of 187 kA at 240 V AC means it can safely clear a fault up to that level without upstream devices needing to trip — critical for high-fault-current service entrances or transformer secondaries where the available short-circuit current is substantial. At 415 V and 440 V the rating holds at 121 kA, dropping to 75.6 kA at 500 V and 3.7 kA at 690 V, so the SCCR coordination study should reference the actual line-to-line voltage of the installation. This variant includes a shunt trip (STL) auxiliary release, allowing remote tripping via a control signal — useful for emergency-stop circuits or supervisory shutdown sequences. It does not carry undervoltage release or ground-fault monitoring, so those functions would need external modules if required. The 10 W maximum power loss is modest for a 100 A frame, keeping panel heat rise manageable in a densely packed enclosure.
Dimensions and panel fit
The breaker occupies 105 mm width, 181 mm height, and 86 mm depth — a standard 3-pole MCCB footprint for the 100 A frame class. Mounting holes and bus-bar connection centers follow the SENTRON 3VA pattern, so it drops into existing panel layouts that were designed for the same frame size. The 86 mm depth (3.39 in) leaves clearance behind the panel door for wiring and auxiliary wiring channels.
Thermal performance across ambient range
The 100 A continuous rating holds flat from 40 °C through 70 °C ambient — no derating needed across the typical industrial panel temperature range. That simplifies panel design: the breaker delivers its full nameplate current even in a warm enclosure near other heat sources. The operating temperature range spans -25 °C to 70 °C, with storage from -40 °C to 80 °C.
