Molded Case Circuit Breaker for Line Protection
The Siemens SENTRON 3VM1196-5ED32-0AA0 is a 3-pole molded case circuit breaker (MCCB) designed for line protection, carrying a rated current of 16 A across its operating range from -25 °C to 70 °C, with a rated insulation voltage of 800 V. Its TM210 thermal-magnetic release handles overloads and short circuits, with a maximum breaking capacity of 187 kA at 240 V AC, 121 kA at 415 V, 76 kA at 440 V, and 17 kA at 500 V — the numbers drop as system voltage rises, so the 415 V figure is the one to size against for common industrial distribution panels.
Thermal Derating and Panel Fit
The 16 A rating holds steady from 40 °C through 55 °C, then derates to 15 A at 60 °C through 70 °C — no headroom loss in a warm enclosure until you cross 60 °C, which covers most ventilated panels. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep, with IP40 protection on the front face — fits standard panel cutouts for 3-pole MCCBs in this frame class, and the IP40 front keeps tools and fingers out during operation.
