The Siemens SENTRON 3VA1196-3ED22-0AA0 is a 2-pole molded case circuit breaker rated for 16 A continuous duty across a 40 °C to 55 °C ambient range, with a thermal-magnetic TM210 overcurrent release. Breaking capacity hits 75.6 kA at 240 V AC and 52.5 kA at 415 V AC, so it handles high-fault utility feeds without needing an upstream current-limiting fuse. At 70 °C ambient the rating drops to 15 A — still a solid 15 A, but if your panel runs hot near a transformer or drive, size the load accordingly. Insulation voltage is 500 V, operating voltage 415 V AC or 250 V DC, so it covers most industrial control panels and lighting distribution boards.
The case measures 50.8 mm wide, 130 mm tall, 70 mm deep — a 2-inch wide footprint that fits standard panel-mount cutouts for 2-pole MCCBs.
