Electromagnetic Industries Ground Fault Current Detection GFM 453

Electromagnetic Industries Ground Fault Current Detection GFM 453Electromagnetic Industries Ground Fault Current Detection GFM 453 Application: These Class 1 (Model GFM) Ground Fault protection systems are used to minimize damage to equipment due to arcing ground faults. The GFM system is designed for all polyphase applications and is ideal for motor control, motor control centers and high voltage starters. Systems can be wye or delta, grounded or resistance grounded. Operating Range (Adjustable): Trip Currents models are available for 1.5 to 65 Amps,depending on sensor. Time Delay (Adjustable): Instantaneous to 36 cycles Input Power: Self Powered Frequency: 50/60 Hz Ambient Temperature Range: -30 Deg C. to 60 Deg C. • Inverse time characteristic (to preventnuisance trip)• Field adjustable trip relay (trip current)• Adjustable trip time delay relay (field settablefor up to 36 cycles)• Positive Visual Trip Indicator• SPDT contacts: Form C, rated for 10 Ampscontinuous, 23 Amps inrush (250 VAC)• Door or Panel Mounted options• Operates with molded case power circuitbreakers, bolted pressure switches, or fusibledisconnect switches.
