Control supply is 24–240 V AC/DC (50/60 Hz). The two changeover contacts give you independent alarm or trip outputs, which fits a standard motor control center (MCC) scheme: one contact for an upstream breaker trip, the other for a PLC alarm. On-delay and trip-delay are both adjustable from 0.1 to 999.9 seconds, so you can ride through inrush or transient events without nuisance trips. ## Integration notes — panel space and wiring Packaged dimensions are 127 x 111 x 38 mm — that is a standard 4-module wide DIN-rail footprint. Control supply is galvanically isolated from measuring inputs, allowing separate 24 VDC power while monitoring a motor circuit.","metaTitle":"Siemens 3UG5642-1CW30 Digital Monitoring Relay, 24-240 V AC/","metaDescription":"Siemens 3UG5642-1CW30 digital monitoring relay for current, voltage, power factor, and power up to 690 V AC/DC, 10 A.
