Instruction for the
Cutler-Hammer Type MPCV
Network Protection Relay
GE Relay Installation Notes
MG8/9 — 125/216 V with Watt-Var
1. For delayed sensitive operation using electromechanical
relays (Type CHN, CHL) RED button is placed on Stud
50. For sensitive operation without Time Delay, RED
button is placed on Stud 41A. Short WHITE button is
placed on other stud to insulate. Delayed sensitive
function is incorporated within MPCV Relay. When
applying MPCV Relay with delayed sensitive function,
RED button must be on Stud 41A. Remove “OR” device
and add jumpers between 17 – 18, 27 – 28 and 37 – 38.
2. The MPCV Relay is housed in one case and is received
into the master relay (CHN) connector. No connections to
phasing relay (CHL) plug is necessary except for a jumper
across terminals 1 and 2 (wire No. 6 – 6A). Lifting wire
6A and attaching to terminal wire 6 can accomplish this.
All field units previously having Type CHN – CHL relays
also require the addition of a wire from master relay plug
terminal 4 to ground.
3. Watt-var function is incorporated within the MPCV Relay.
When applying an MPCV Relay with or without watt-var
function, add jumpers between “HGA” terminals 1 – 7 and
2 – 8. Remove wires from “HGA” terminals 3 and 4.
MG8/9 — 277/480 V with Watt-Var
1. For delayed sensitive operation using electromechanical
relays (Type CHN, CHL) RED button is placed on Stud
50. For sensitive operation without Time Delay, RED
button is placed on Stud 41A. Short WHITE button is
placed on other stud to insulate. Delayed sensitive
function is incorporated within MPCV Relay. When
applying MPCV Relay with delayed sensitive function,
RED button must be on Stud 41A. Remove “OR” device
and add jumpers between 17 – 18, 27 – 28 and 37 – 38.

3. Watt-var function is incorporated within the MPCV Relay.
When applying an MPCV Relay with or without watt-var
function, add jumpers between “HGA” terminals 1 – 7 and
2 – 8. Remove wires from “HGA” terminals 3 and 4.
MG14 — 125/216 V with Watt-Var
1. For delayed sensitive operation using electromechanical
relays (Type CHN, CHL) add “TD” device and jumpers to
“OR” device. Delayed sensitive function is incorporated
within MPCV Relay. When applying MPCV Relay with
delayed sensitive function, remove external “TD” and
“OR” devices and add jumpers between 17 – 18,
27 – 28, 37 – 38 and 41 – 45.
