Latching Relay MMK CSM MMK DS E 5 2 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 55C. Refer to Safety Precautions for All Relays.

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.
