Two independent SPDT outputs provide separate control signals for interlocks, alarms, or logic inputs. This separation reduces cross-interference in control circuits and improves fault signaling clarity. In motor protection and drive applications, that means cleaner interlock logic and faster fault response. Measuring range (L-L) 160-300 V AC with rated control supply 160-300 V AC and support for 50/60 Hz ensures easy integration with existing power networks, reducing configuration errors in feeders, panels, and machine skids. ON-delay options (start-up delay 200 ms; tripping delay 0 s or 0.1–30 s) minimize nuisance trips during transient events, delivering smoother operation for pumps, fans, and conveyors in production lines. Screw terminals support a wide wire range (0.5–4 mm²) and double-chamber cage connections for reliable wiring in harsh environments, cutting commissioning time and improving vibration resistance. DIN-rail mounting on TH35-15 or TH35-7.5 rails and a compact 22.5 mm width save panel space while enabling quick replacement in standard enclosures. CE, UKCA, UL/CSA certifications underpin regulatory compliance, and an optional sealable cover adds security for maintenance windows in busy facilities. Together, these features deliver lower lifecycle costs, higher uptime, and safer machine operation in industrial automation environments.

Install the CM-PAS.31S on a TH35 DIN rail (TH35-15 or TH35-7.5) in a control panel. Use screw terminals to connect input power (160-300 V AC) and the two SPDT outputs, observing the 0.5–4 mm² conductor range and 0.6–0.8 N·m tightening torque. Ensure proper clearance and secure wiring to avoid vibration-related faults.
The device monitors phase failure, phase sequence, and phase unbalance with a measuring range of (L-L) 160–300 V AC. This enables detection of incorrect phase sequence, loss of a phase, or unbalanced voltages, enabling timely protective actions in motors and drives.
Yes. The relay carries UL/CSA recognition, with UL/CSA specific ratings for the output circuit (B300) and conductor connections. It supports safe operation in UL 508 compliant panels and is suitable for global applications requiring UL/CSA certification.
The CM-PAS.31S operates at supply frequencies of 50/60 Hz, with an ON-delay that can be 0 seconds or 0.1–30 seconds, plus a startup delay of 200 ms. This allows tuning to machine start-up characteristics and reduces nuisance tripping in variable-load processes.
The device offers a sealable protective cover to prevent unauthorized changes, IP50 housing protection, and accessible screw terminals for straightforward field wiring. These features improve maintenance security, simplify compliance checks, and reduce unscheduled downtime during service windows.
