Product Model

CM-MPS.41S

Technical Specifications

• Measuring range (phase–phase voltage): 3 × 300 … 500 V AC (50/60 Hz)

• Supply/measurement voltage: 3×300 … 500 V AC

• Output contact configuration: 2 c/o (DPDT – double pole change-over)

• Contact rating: Up to 250 V AC / 4 A (AC-12)

• Start-up delay ≤ 200 ms; trip delay selectable as instantaneous or 0.1 … 30 s

• Monitored functions: phase sequence monitoring, phase failure detection, over-voltage/under-voltage detection, three-phase unbalance detection

• Mounting: DIN-rail (35 mm)

• Dimensions: Width 22.5 mm × Height 85.6 mm × Depth 103.7 mm

• Ambient operating temperature: –25 … +60 °C

• Degree of protection: Housing IP50 / Terminals IP20

• Connections: Screw terminals, double-chamber cage terminal design

Advantages & Key Features

• Comprehensive protection: Combines multiple monitoring functions (phase loss, reverse phase, over/under-voltage, phase unbalance) in a single unit.

• Flexible configuration: Adjustable trip delays (instant to 30 s) and adjustable thresholds for voltage and phase imbalance accommodate diverse system requirements.

• Compact design: Narrow width (22.5 mm) makes it ideal for high-density control cabinets and tight spaces.

• Easy installation: DIN-rail mounting and screw-type terminals simplify integration into industrial panels.

• High reliability: With built-in start-up delay and monitoring logic, it offers protection to motors and equipment by responding swiftly to anomalous supply conditions.

• Wide voltage application: Suitable for three-phase systems in the 300–500 V range, offering broad applicability across industries.

Applications

• Industrial motor protection: Used to monitor three-phase supply for critical motors and prevent damage caused by phase failure, reverse phase or imbalance.

• Power distribution systems: Provides three-phase voltage and sequence monitoring in main and sub-distribution boards.

• Elevators, fans, pump drives: Ensures reliable supply quality for large load-driven systems, protecting mechanical assets.

• Automation control panels: Embedded in process control cabinets, checking the three-phase supply before critical equipment starts.

• Backup or change-over power systems: Monitors incoming three-phase feeds to ensure sequence and voltage correctness before engagement of backup sources.

Precautions

• Verify that the system voltage matches the device’s rated range (3×300–500 V AC) before installation.

• Ensure that L1, L2, L3 connections are correct and terminals are firmly tightened to avoid false trips caused by loose connections.

• During commissioning, properly set the trip delay and unbalance threshold so as not to trigger during normal transient voltage fluctuations.

• Install in a location that meets the ambient temperature specification (–25 … +60 °C) and avoid locations with heavy vibration, corrosive atmosphere or high dust levels.

• This device provides monitoring/protection functions but does not replace primary protection devices like circuit breakers or fuses — use in conjunction with the full protective scheme.

• Before applying large loads or switching heavy equipment, test the relay’s response to ensure correct operation under real conditions.
