What it is and what the ratings mean
The Siemens SENTRON 3VM1196-3ED22-0AA0 is a 2-pole molded case circuit breaker (MCCB) rated 16 A continuous at 40 °C, with a TM210 thermal-magnetic overcurrent release. The 76 kA interrupting capacity at 240 V AC means it can safely clear a fault up to that level without upstream cascading — critical for high-fault panels where the available short-circuit current is substantial. At 415 V AC the interrupting rating is 53 kA, still well above typical industrial service-entrance levels. The 70 mm depth and 50.8 mm width fit standard DIN-rail or panel-mount footprints; IP40 on the front keeps dust out of the enclosure face.
Deployment context
Designed for line protection in distribution panels, this MCCB mounts on DIN rail or directly to a backplate. The 2-pole configuration suits single-phase or two-wire DC circuits up to 250 V DC. Rated insulation voltage is 500 V, so it handles standard 400 VAC three-phase panels with margin. No undervoltage release, no ground-fault monitoring — it's a straightforward thermal-magnetic breaker for branch-circuit protection.
