This breaker's interrupting capacity changes with system voltage: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. At 415 V — the most common industrial distribution voltage in many regions — 75.6 kA SCCR gives you headroom for high-fault panels without cascading upstream. The 690 V figure is lower but still covers most standard transformer-fed installations. ## Thermal derating — the real-world current you can carry Above that it derates: 15.36 A at 55 °C, 15.04 A at 60 °C, 14.72 A at 65 °C, and 14.4 A at 70 °C. If your panel internal temperature runs hot — sealed enclosure, high-density layout — factor the 55 °C or 60 °C row into your load calculation. ## Auxiliary trip and release options The integrated auxiliary trip is part number 3VA9688-0BL33. It is a clean, no-frills line protection breaker with one remote-trip channel.","metaTitle":"Siemens 3VA1196-4EF32-0KA0 SENTRON MCCB, 16 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1196-4EF32-0KA0 molded case circuit breaker, 16 A rated, 3-pole, line protection.
