Breaking capacity hits 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V, so it handles high-fault scenarios on 480 V or 600 V class systems without cascading upstream. Undervoltage release (UVR) is fitted from the factory, which drops the breaker if control voltage falls below the dropout threshold — common for emergency-stop or undervoltage protection schemes. Insulation voltage rated 800 V, power loss at full load maxes at 40.5 W. At 55 °C it drops to 158 A, at 60 °C to 155 A, at 65 °C to 153 A, and at 70 °C to 150 A.","metaTitle":"Siemens 3VA1116-3EF32-0BA0 SENTRON MCCB, 160 A, 3-Pole, 75.6","metaDescription":"Siemens 3VA1116-3EF32-0BA0 SENTRON molded case circuit breaker, 160 A at 40 °C, 3-pole, 75.6 kA breaking capacity at 240 V.

For a 480 V system, the 440 V figure (32 kA) is the conservative reference point since 480 V falls between those two tested voltages."},{"question":"What does the TM240 overcurrent release mean?","answer":"TM240 is a thermal-magnetic release with a fixed 240 A frame. The continuous current is set by the rating plug — in this case 160 A at 40 °C. The thermal element protects against overload; the magnetic element handles short-circuit trips."},{"question":"Does this breaker include an undervoltage release?","answer":"Yes, it comes with an undervoltage release (UVR) fitted from the factory. It trips the breaker when control voltage drops below the dropout threshold, used in emergency-stop or undervoltage protection circuits."},{"question":"How do I get pricing and availability for 3VA1116-3EF32-0BA0?","answer":"Submit an RFQ through this listing.
