What this 1-pole MCCB does on the line
The Siemens 3VA1196-3ED16-0AA0 is a 1-pole SENTRON molded case circuit breaker sized for 16 A continuous at 40 °C ambient, with the TM210 thermal-magnetic release tuned for line protection — no undervoltage release, no ground-fault monitoring, no communication module. At 240 V AC it interrupts faults up to 52.5 kA; at 415 V AC the breaking capacity drops to 7.5 kA, which is the number to watch if your panel feeds a 400 V bus. The 25.4 mm width (one inch) and 70 mm depth let it slot into a standard DIN-rail enclosure without crowding adjacent poles.
Rated current holds flat at 16 A from 40 °C through 55 °C; at 60 °C it derates to 15 A, and at 70 °C it stays at 15 A. That means no thermal headroom penalty in a warm panel unless you push past 55 °C — useful for a tightly packed row of breakers. The 52.5 kA interrupting rating at 240 V AC is the headline number, but the 7.5 kA at 415 V AC is the one that governs a 400 V three-phase distribution board; if your available fault current at the panel exceeds 7.5 kA at 415 V, this breaker needs an upstream current-limiting device. Power loss is 3.53 W max — negligible for heat budgeting in a multi-pole assembly.
Mounts on DIN rail via the integral clip. Front IP40 is standard for a distribution board — no gasket needed for dry indoor enclosures. The 70 mm depth leaves clearance behind a typical 100 mm deep gland plate; no right-angle cable bend issues. No auxiliary contacts or shunt trip are built in (no undervoltage release, no trip indicator), so if the BOM calls for remote signaling, you need the separate 3VA accessories kit.
