Feature → Business Impact → Application: The CM-PSS.41S provides phase failure detection, phase sequence monitoring, and over-/undervoltage monitoring, enabling targeted protection for motor circuits and critical loads. This reduces unexpected shutdowns and extends motor life by preventing stress from improper phase conditions. Application includes switchgear panels and machine controls where consistent phase integrity is essential. Feature → Business Impact → Application: With a rated control supply of 400 V AC and a measuring range of 360–440 V AC, it fully covers typical European 3-phase networks, reducing the need for additional converters and simplifying installation in new or retrofit projects. This is ideal for conveyor systems and packaging lines where uptime is critical. Feature → Business Impact → Application: The device offers 2 c/o (SPDT) contacts with screw terminals, facilitating straightforward wiring and reliable fault signaling to plc inputs. This simplifies commissioning and improves diagnostic clarity in control cabinets. Feature → Business Impact → Application: Adjustable ON or OFF tripping delay (0 to 30 s) allows tailoring protection to motor inrush and load dynamics, lowering nuisance trips while maintaining safety. This is beneficial for pump and fan applications with variable startup behavior. Feature → Business Impact → Application: Screw connection technology with double-chamber cage terminals and a 22.5 mm width compactly fits DIN rail frames, enabling dense, compliant control panels and faster maintenance. This supports easier upgrades and scalable installations in manufacturing lines. Feature → Business Impact → Application: Compliance with IEC/UL standards (e.g., IEC 61000-6-2, IEC 61000-6-3, UL 508), plus IP50 protection, ensures resilience against industrial electromagnetic interference and environmental exposure, reducing regulatory risk and service costs. This is crucial for food and beverage or packaging lines with strict regulatory expectations and harsh environments.

Install CM-PSS.41S on TH35 DIN rails (TH35-15 or TH35-7.5) using the screw terminals for easy wiring. Torque range is 0.6–0.8 N·m, with wire sizes from 0.5 to 2.5 mm² (or 0.5–4 mm² depending on conductor type). Ensure ambient temperature remains within -25 to +60 °C and maintain IP50 protection for the housing.
CM-PSS.41S monitors phase loss, phase sequence, and over- and undervoltage on L-L 360–440 V AC with a 400 V AC control supply. It provides 2 c/o SPDT outputs, enabling both normally closed and normally open signaling for downstream interlocks or PLC inputs.
Yes. It carries CE and UL/CSA certifications (UL 508 compatible) and can be used in CAN/CSA environments, with additional declarations like CCC and UKCA where applicable, ensuring broad regulatory compliance for industrial control panels.
Yes. It is designed for 400 V AC control and 360–440 V AC measuring voltage, making it suitable for protection of motors and equipment connected to common European 3-phase networks.
Use the sealable cover accessory for protection against tampering, ensure proper tightening torque, and leverage the screw-terminal design for reliable connections. DIN-rail mounting plus compact dimensions enable high-density panels, reducing cabinet space, wiring time, and retrofitting costs while improving uptime.
