Component Protective Components

These Components monitor power supply circuits for industrial equipment and manufacturing facilities to protect components from overcurrents, overvoltages, ground leakage, phase loss, reversed phases, and other faults.

There are Detectors for High-precision Detection of heater burnout , High-capacity (4 to 80 A AC) Detectors with built-in CTs, and Compact Plug-in Burnout Detectors with low capacities (0.5 to 4 A AC).

Voltage Detectors are available for detecting undervoltage and overvoltages for AC or DC power. AC and DC Voltage Detection Relays that can be operated and reset are also available.

A lineup of DeviceNet-compatible Motor Protective Relays and Relays for motor/transformer protections, three-phase motor reverse operation prevention, and motor/heater burnout protection.
