Instruction for the

Cutler-Hammer Type MPCV

Network Protection Relay

Relay Replacement Guidelines

The MPCV Relay is designed as a direct replacement for the

EMMR (Electromechanical Master Relay), EMPR (Electro-

mechanical Phasing Relay), SSNPR (Solid-State Network

Protector Relay), DNPR (Digital Network Protector Relay),

MPCR (Microprocessor Network Protector Relay) relays

without wiring modifications on the protector. Additional

wirings are needed from the “b” contact of the protector to

Aux –1 (points 7 and 8) of the relay when communications

are used or when anti-pumping feature is activated.

A network protector manufactured by Eaton, Richards or GE

can use the MPCV Relay without any wiring modifications.

There are five different relay styles that can be used to match

any protector style. The protective and safety features of the

relay are still operational when used with other protectors

made by other manufacturers.

1. MPCV-D

(216 V) Style# 6417C82G01

2. MPCV-22 (216 V) Style# 6417C83G01

3. MPCV-2X (216 V) Style# 6417C83G03

4. MPCV-GE (216 V) Style# 6417C84G014

5. MPCV-P

(216 V) Style# NAS0129G01

Kits include Relay, CNJ Jumper Plate, Wiring Kit and

Instruction Book unless otherwise noted.

Table 8. MPCV-D (216 V) — Relay # 6417C82G01 — Kit # 8231A80G05

For use in CMD Network Protectors having GRD-Y

connected CTs. Relay will replace:

Table 9. MPCV-22 (216 V) — Relay # 6417C83G01 — Kit # 8231A80G08

For use in CM-22 and CMR-8 Network Protectors having

energized CTs. Relay will replace:

Table 10. MPCV-2X (216 V) — Relay # 6417C83G03 — Kit # 8231A80G03

For use in CM-22 and CMR-8 Network Protectors having

GRD-Y connected CTs. Relay will replace:

Note: Kit # 8231A80G07 is available for converting from 480 V

Electromechanical Relays and includes the relay, CNJ Jumper Plate,

Wiring Kit, Instruction Book, and 3-Phase Potential Transformer.
Note: Units with energized CTs can be changed to GRD-Y connected

CTs based on instructions noted in Relay Conversion Guidelines

on Page 26.

Table 11. MPCV-GE (216 V) — Relay # 6417C84G01 — Kit # 8231A80G06

For use in GE MG-8, MG-9, MG14 and MG-14A Network

Protectors using electromechanical Type CAN or CHN master

and Type CAL or CHL phasing relays. Will also replace any

GE network breaker wired for the solid-state analog type

SSNPR relay. Relay will replace:

Table 12. MPCV-P (216 V) — Relay # NAS0129G01

For use in MV Substation Breaker control. Wires are termi-

nated in a two 9-pin terminal block. Relay will replace:
