Latching Relay
MMK
CSM_MMK_DS_E_2_1
Mechanically Latching Relays Based on the
MM Power Relay
• Low power consumption due to mechanical latch for economic
operation.
• 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
applications.
• Ambient operating temperature: –10°C to 55°C.
Refer to
Safety Precautions for All Relays.

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.
Note:
When ordering, add the rated coil voltage to the model number. Rated coil voltages are given in the coil ratings table.

2.
If L/R exceeds 7 ms when switching DC inductive loads, an arc-breaking time of up to 50 ms must be considered in application and the
circuit must be designed to ensure that an arc-breaking time of 50 ms is not exceeded.
