ATC Diversified Electronics CMU100 Multifunction AC Current Monitoring Relays
ATC Diversified Electronics CMU100 Multifunction AC Current Monitoring Relays are versatile devices that automatically detect and respond to dangerous current fluctuations. These relays intervene to prevent damage and maintain the safe operation of devices when the current exceeds or falls below the threshold. The CMU100 monitor relays feature an adjustable time delay, less than 0.1%/°C temperature dependency, SPDT contact form, 1.2W maximum power dissipation, and 10,000,000 operations mechanical life. These relays are used in motors, heating cables, and lamps.
