The Full Current Output Option Relay 139-H-FLC is a horizontal mounting specialty model.

This model has an external reset switch that works in conjunction with the front panel reset switch.

This model also has an emergency restart option.

Product Description

Model 139-H-FLC is a full load current horizontal mount motor protection relay.

This model has a full load current of 4 to 20 milliamps. Associated protections listed for this relay include overheating, stall-mechanical blocking,

Rotor Lockout, Undercurrent, Ground Fault, Single Phase/Unbalance, Repeat Start, and Overload Protection with selectable curves.

This relay will protect three-phase AC motors from environmental influences that can cause damage.

The 139-H-FLC relay will be used in six applications; one of the applications is to ensure user safety.

This application will utilize the ground fault function to find leakage currents caused by moisture or potential winding shorts in mines, thus preventing shock hazards.

As mentioned above, the relay will be mounted horizontally; it should be noted that a rectangular panel cutout is required for whichever mounting orientation is chosen for the relay.

Once the current breaker is available, the relay will be held in place by two U-clips and then prepared for wiring.

The 139-H-FLC relay can be supplied with ground fault current and it will accept all current carrying conductors through the ground fault current window.

Please note that it is highly recommended that at least two current leads need to be wound together to minimize noise pickup on the relay.

There is a specially designed current that can be used to help output lower level signals.
