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:
