Other sensors

Eaton Cutler-Hammer CurrentWatch is a series of sensors for current sensing, AC and DC. The sensors come in three basic designs for

• Monitoring of over or underload - output in the form of contact switching
• Convert current to analog output - 4-20 mA/0-5 V/0-10 V, linearly proportional to the measured current
• Earth leakage monitoring - output in the form of contact switch, 5/10/30 mA fault current

CurrentWatch can monitor systems up to 300 A. Most models are available in versions with solid or split core. Several models require no external power supply. All models measure the current with high accuracy and have a very short response time. Most versions are both UL approved and CE certified.
