This gives the site electrical engineer flexibility to match the breaker to the actual cable and load without swapping trip packs. The 24 V DC universal release accessory powers a shunt trip or undervoltage release — common in remote-trip or safety-circuit applications where a control signal must open the breaker independently of the thermal-magnetic mechanism. ## Integration notes The 24 V DC release and the two auxiliary changeover switches (1 NO + 1 NC each) plug into the accessory slots on the left side of the mechanism — verify polarity on the release coil before energizing. The TM240 trip unit is field-adjustable, so no separate rating plug is needed.","metaTitle":"Siemens 3VA1463-5EF32-0LH0 Circuit Breaker, 630A, 55kA @ 415","metaDescription":"Siemens 3VA1463-5EF32-0LH0 IEC frame 630 MCCB, 55kA breaking capacity at 415V, 3-pole, TM240 trip, 440-630A Ir, 24 VDC release.
