The Siemens SENTRON 3VA1196-6EF32-0DA0 is a 3-pole molded case circuit breaker rated for line protection at 16 A continuous current, with a TM240 thermal-magnetic overcurrent release. Its interrupting capacity hits 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — numbers that tell you this breaker is built for high-fault panels where a standard MCB would weld shut. The 70 mm depth and 76.2 mm width fit the standard SENTRON 3VA footprint, so it drops into existing DIN-rail or panel-mount layouts without re-drilling.
What the ratings mean for your panel
The 16 A rating holds flat from 40 °C to 50 °C, then derates to 15.36 A at 55 °C and 14.4 A at 70 °C. That means in a warm enclosure — say, a packed panel with drives — you lose about 1.6 A off the nameplate. The TM240 release is a fixed thermal-magnetic curve, not adjustable, so it's a set-it-and-forget-it choice for feeder or branch protection where the load is known. Rated insulation voltage Ui is 800 V, and the breaker carries 17 kA at 690 V — useful if you're on a 690 V industrial network. The IP40 front protection means it's splash-proof from the front but not sealed; mount it inside a cabinet, not in a washdown zone.
Panel integration notes
Width 76.2 mm (3-pole), depth 70 mm, height 130 mm. The 3VA family uses a common mounting pattern, so swapping from another 3VA frame is straightforward — same DIN rail clip, same busbar pitch. No auxiliary contacts on this variant, so if you need status feedback, you'll add the separate auxiliary trip module. The undervoltage release is present, so verify coil voltage matches your control circuit before wiring.
