The Siemens SENTRON 3VA2110-7MN36-0CA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to that ceiling. Its interrupting capacity hits 330 kA at 240 V and 242 kA at 415 V, which puts it squarely in the high-fault category for industrial main feeders or large motor branch circuits. The motor protection design includes phase failure detection and an undervoltage release (UVR) as standard. No trip indicator on the front face; fault status is read from the handle position.
Interrupting capacity across voltage levels
The 330 kA at 240 V is the headline number, but the real-world fit depends on the system voltage. At 415 V and 440 V it still holds 242 kA; at 500 V it drops to 187 kA. At 690 V the interrupting capacity falls to 3.7 kA — that's the point where you need to check whether the available fault current at the panelboard stays under that limit. For a 480 V distribution panel in North America, the 187 kA at 500 V covers most utility transformer sizes.
Mounting and panel fit
The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep. That 105 mm width is the standard 4-module footprint for SENTRON 3VA molded case breakers — it clips onto a DIN rail or mounts directly to a backplate. The 86 mm depth leaves clearance for rear-connected busbars or a cable-entry gland plate. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.
