The interrupting capacity is voltage-dependent: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. That 7.5 kA floor at higher voltages is the figure to verify against the available fault current on a 690 V line. The 76.2 mm width is a standard 3-pole MCCB footprint — three modules at 25.4 mm per pole — so it drops into existing SENTRON or comparable panel layouts without re-drilling the mounting plate. Suitable for indoor panel mounting; not rated for washdown environments. Maximum power dissipation is 5.7 W at rated load — a modest heat contribution, but worth including in the panel thermal budget if multiple breakers are ganged.","metaTitle":"Siemens 3VA1192-5MG36-0AA0 SENTRON MCCB, 3-Pole, 12.5 A, 187","metaDescription":"Siemens 3VA1192-5MG36-0AA0 SENTRON molded case circuit breaker, 3-pole, 12.5 A rated, 187 kA interrupting at 240 V.
