The Siemens SENTRON 3VA1196-3ED32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current Iu of 16 A at 40 °C through 55 °C, derating to 15 A at 60 °C through 70 °C. It uses a TM210 thermal-magnetic overcurrent release — a fixed thermal element with a magnetic trip adjustable up to 320 A (li max), which means you set the short-circuit pickup to match the inrush of your downstream load without nuisance tripping on motor starts or transformer energization.
This breaker delivers 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. If your service entrance or transformer secondary can deliver, say, 65 kA at 240 V, this breaker has headroom; if it's 85 kA, you need a higher-rated frame or a current-limiting upstream device.
Dimensions are 130 mm tall, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON distribution panels and switchboard cubicles without re-drilling.
