Industrial 211L5 1 8CCB Electromagnetic Bobbin Wound Coil

Description:

The No Name 211L5 Bobbin Wound Coil is an electromagnetic coil designed for use in field loss relays, motor protection circuits, and industrial control systems. Commonly installed in DC motor drives, shunt wound motors, and relay assemblies requiring continuous field current monitoring and protective tripping functions. Maintenance teams, OEMs, and industrial electricians use this coil for equipment repairs, relay rebuilds, and replacement of worn or damaged field loss relay coils. Field loss relays protect DC motors from overspeed conditions caused by loss of field excitation.

Applications:

The No Name 211L5 Bobbin Wound Coil is designed to energize a field loss relay used in DC motor control systems. It is commonly used in cranes, rolling mills, printing presses, hoists, DC drives, and industrial machinery employing shunt or compound wound DC motors. When connected in series with the motor field circuit, the relay coil monitors field current and trips the control circuit if excitation is lost, protecting the motor and driven equipment from overspeed and mechanical failure.
