It's configured for line protection — meaning it sits at the feeder or main distribution point, not downstream on a motor or branch circuit. The interrupting ratings are the headline: 187 kA at 240 V, 121 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V. At 55 °C it drops to 155.6 A, at 60 °C to 151.2 A, at 65 °C to 146.8 A, and at 70 °C to 142.4 A. If your panel ambient is 50 °C or below, you get the full 160 A; above that, the thermal curve governs. The TM240 release means the thermal pickup is fixed at 160 A (the frame rating), and the magnetic trip is set at 240 A — that's a 1.5x multiple, which is typical for feeder protection where you want to ride through motor inrush without nuisance tripping. Mechanical endurance is rated at 15,000 operations — that's the latching endurance figure. For a main breaker that cycles once or twice a day, that's decades of service. For a frequently switched load, it's a constraint to note. Inside a closed panel, that's standard. The undervoltage release and auxiliary contacts are factory-integrated, so no field assembly of add-on modules is needed — that saves panel-build time.","metaTitle":"Siemens 3VA1216-5EF32-0BH0 SENTRON MCCB, 160 A, 3-Pole, 187","metaDescription":"Siemens 3VA1216-5EF32-0BH0 SENTRON molded case circuit breaker, 160 A rated, 3-pole, interrupting 187 kA at 240 V.
