For a panel builder, that means you can load it to 125 A in a ventilated enclosure without worrying about nuisance tripping until the ambient climbs past 50 °C. Breaking capacity is where this part earns its place in high-fault installations: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. Three-pole, 76.2 mm wide (3 inches), 130 mm tall, 70 mm deep. The breaker ships without an undervoltage release or shunt trip (no voltage trigger, no trip indicator), so if the spec calls for remote tripping, you add the 3VA auxiliary switch block — the design accepts up to three auxiliary switches HQ. Maximum power loss is 28.1 W at rated current. In a sealed, non-ventilated enclosure with multiple breakers, that heat adds to the internal temperature rise — factor it into your thermal calculation if the panel ambient approaches the 70 °C operating maximum.","metaTitle":"Siemens 3VA1112-5EF36-0AD0 SENTRON MCCB, 125 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA1112-5EF36-0AD0 molded case circuit breaker, 125 A rated at 40 °C, 3-pole, TM240 release, 187 kA breaking at 240 V.

Both share the 76.2 mm width per pole and similar mounting pattern, but the TM240 release and 125 A continuous rating mean the trip curve and lug size differ — verify the existing busbar ampacity and lug accommodation before swapping.
