The Siemens SENTRON 3VA2110-5MN36-0KB0 is a 3-pole molded case circuit breaker (MCCB) rated at 100 A continuously across the full 40 °C to 70 °C ambient range — no derating needed up to 70 °C, which simplifies panel layout in warm enclosures. Its interrupting capacity hits 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 — the 187 kA figure at 240 V means it can clear a high-fault bolted short circuit on the secondary of a large distribution transformer without the arc re-striking. Phase failure detection is onboard; undervoltage release and ground-fault monitoring are not included in this variant, so if those functions are required, specify a different order code or add external modules.
Maximum power loss is 10 W.
