At 415 V it still holds 154 kA, and at 500 V and 690 V it's rated 17 kA. This is not a motor-protective breaker — its design is explicitly for line protection, meaning it guards cable and busbar feeders against short-circuit and overload. The UVR means the breaker trips automatically when supply voltage drops below a threshold — typical for safety circuits where a machine must stop on power loss. The auxiliary switches give remote status feedback (open/closed/tripped) to a PLC or indicator lamp. The breaker occupies a 76.2 mm wide by 130 mm tall by 70 mm deep footprint — standard for a 3-pole SENTRON MCCB in this frame size. The undervoltage release coil wiring and auxiliary switch terminals are accessible from the front; no special panel cutout needed beyond the width allowance.","metaTitle":"Siemens 3VA1140-6EF32-0DH0 SENTRON MCCB, 40 A, 220 kA at 240","metaDescription":"Siemens SENTRON 3VA1140-6EF32-0DH0 molded case circuit breaker, 40 A rated, 220 kA breaking capacity at 240 VAC. 3-pole, line protection, with undervoltage release.
