Component Protective Components

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.

There are both manually and automatically reset Ground Leakage Relays, Multi-point Ground Leakage Relays that detect ground leakage and temperature, DC Fault Detection Relays to detect earth-fault accidents, and Class A Ground Leakage Fire Alarms for ground leakage alarms.
