Phase loss detection and interrupted neutral monitoring delivers early fault signaling to the control system. This translates into a tangible business impact by reducing unplanned downtime and motor stress, improving equipment life. These capabilities are ideal for commissioning in single- or three-phase mains within industrial automation panels, where compact monitoring devices must coexist with PLCs and motor starters. A 1 NO contact with a 4 A at 250 V rating provides a clear signaling path to the control logic. The straightforward wiring interface simplifies panel design and minimizes wiring errors, reducing installation time and post-wire checks. It is well-suited for interfacing with PLC inputs, relays, and safety interlocks in conveyors, fans, and pumps. Measuring ranges cover (L-L) 380-440 V and (L-N) 220-240 V, giving flexibility across regional supply networks. This reduces the need for additional transformers or adapters, lowering cost and inventory. In practice, engineers deploy the device across mixed environments where supply voltages vary. Startup delay of 500 ms and a tripping delay of 150 ms provide deliberate timing to suppress transient disturbances. The result is fewer nuisance trips during motor startups or voltage sags, improving process stability. This makes it a reliable choice for drives and automation tasks with moderate inrush characteristics. DIN rail mounting on TH35-15 or TH35-7.5 and screw-terminal wiring streamline installation. Tightening torque and conductor ranges support secure, vibration-resistant connections in harsh environments. The device fits neatly into compact control cabinets alongside other CM-range monitors. Environmental and compliance ratings add resilience and regulatory assurance. With IP50 housing, operation from -20 to +60 C, and multi-region certifications (CE, UL 508, UKCA, cUL), the relay supports global panel builds. This translates to easier maintenance, faster upgrades, and lower total cost of ownership.

FAQs
Mount the device on a TH35 DIN rail (TH35-15 or TH35-7.5) and connect wires to the screw terminals. Use the recommended tightness of 0.6-0.8 N·m and wire sections 0.75-1.5 mm2. Ensure the unit is oriented for accessible wiring and verify a secure, vibration-resistant installation in your control cabinet.
Rated control voltage is 220-240 V AC (L-N) or 380-440 V AC (L-L) with 50/60 Hz. Output is 1 normally open contact, 4 A at 250 V. Time characteristics include a 500 ms startup delay and a 150 ms tripping delay to suppress transients and avoid nuisance trips.
Yes. The CM-PBE ( ABB 1SVR550881R9400 ) monitors phase loss and interrupted neutral, making it appropriate for both single- and three-phase mains with neutral. It provides fixed threshold detection suitable for routine industrial control panels.
The relay carries CE, UL 508, and UKCA certifications, among others, plus cUL and CCC listings in various regions. These certifications simplify cross-border panel manufacturing and help ensure compliant integration in diverse environments.
Early fault detection reduces unplanned downtime and motor wear, improving equipment life and process stability. Simple DIN-rail installation and robust environmental ratings minimize maintenance effort, leading to faster deployments and lower total cost of ownership in automated facilities.
