The interrupting ratings are given across the voltage range: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. For a 400 V distribution panel, the 121 kA figure at 415 V gives you the SCCR headroom you need for most industrial service-entrance or sub-distribution applications. The 3VA1112-5ED32-0JA0 occupies a 70 mm depth, 76.2 mm width, and 130 mm height footprint — standard for the SENTRON 3VA platform. The 3-pole construction leaves the neutral pole external if your distribution requires four-wire protection. The shunt trip coil wiring must be routed to a separate control circuit; verify the coil rating against your control voltage source before commissioning. Maximum power dissipation is 28.1 W — account for this heat in a sealed enclosure's thermal budget. No trip indicator is fitted, and there is no undervoltage release, so any undervoltage protection must be handled externally.","metaTitle":"Siemens 3VA1112-5ED32-0JA0 SENTRON MCCB, 125 A, 3-Pole, Shun","metaDescription":"Siemens 3VA1112-5ED32-0JA0 SENTRON molded case circuit breaker, 125 A at 40 °C, 3-pole, TM210 release, shunt trip (STL).
