The Siemens SENTRON 3VA2110-5KQ36-0AA0 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 hits 187 kA at 240 V and 121 kA at 415 V, with a steep drop to 3.7 kA at 690 V — so the voltage class of your feeder determines whether this breaker clears a fault without cascading upstream. Rated insulation voltage is 800 V, and it includes a communication function for integration into monitored power schemes.
Interrupting capacity and voltage dependency
The interrupting ratings are not flat across voltage: at 240 V it clears 187 kA, at 415 V and 440 V it holds 121 kA, at 500 V it drops to 75.6 kA, and at 690 V it falls to 3.7 kA. That 690 V figure is the constraint — if your system runs at 690 V line-to-line, this breaker is only suitable for low-fault-current branches. For a 400 V distribution panel feeding motor control centers, the 121 kA rating comfortably covers most transformer-fed fault levels up to 2.5 MVA.
Thermal performance and operating range
Continuous current holds at 100 A across the full operating temperature range from -25 °C to 70 °C — no derating curve to track. Storage range extends from -40 °C to 80 °C, which is typical for MCCBs stored in unconditioned warehouses. Maximum power loss is 10 W, manageable in a standard enclosure without forced cooling. The lifecycle status is active, meaning this is a current-production catalog item, not a phase-out code.
Physical footprint and panel integration
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or direct-mount panel layouts common in industrial switchboards. The 86 mm depth (3.39 in) is shallow enough for shallow backpan enclosures. Ground-fault monitoring is built in as summation current formation on the L-conductor, so no external GF relay module is needed for that function.
