Latching Relay

MMK

Mechanically Latching Relays Based on the

MM Power Relay

• Low power consumption due to mechanical latch for economic op-

eration.

• Relays with mixed coil specifications can be produced (e.g., AC set

coil and DC reset coil).

• Operational response fast enough to enable pulse signal power ap-

plications.

• Ambient operating temperature: –10

°C to 55°C.

Ordering Information

Models Conforming to Auxiliary Power Relay Specifications

The MM4KP-JD and MM4XKP-JD satisfy the ratings of auxiliary relays provided in JEC-2500 (1987) standards for power protective relays specified

by the Japan Electromechanical Commission. Furthermore, the MM4KP-JD and MM4XKP-JD satisfy the ratings of multi-contact relays provided

in JEC-174D (1979) standards for power auxiliary relays.

These models work at operation level A specified by JEC-174D (1979) standards and the hot start of the relays is possible after the coils radiate

heat.

In accordance with JEC-2500 (1987) standards, the coil of each model withstands a 130% DC load or 115% AC load.
