3 groups of 120A contact switching capability Contact on-off detection auxiliary switch can be provided Coil control single and double coil optional

Please apply a suitable voltage to the coil according to the coil polarity specified in the manual, otherwise the operating voltage of the relay will increase or even not operate; it needs to be changed When driving the polarity, please use the "-R" type relay.

Latching refers to "self-locking", which means that after the relay is energized, its state is automatically locked and the circuit is kept connected. Even if the control current is disconnected at this time, its state will not be changed. That is to say, when the power is energized and absorbed, the control current is disconnected, and it remains on until the unlock button is pressed.

Magnetic latching relay is a new type of relay developed in recent years, and it is also an automatic switch. Like other electromagnetic relays, it automatically switches on and off the circuit.

Latching relays provide smart meter manufacturers with an effective way to reduce standby power consumption while maintaining reliable load switching capability. Because the relay only requires a short pulse when changing state, continuous coil power and unnecessary heat generation can be reduced. For smart meter OEMs and procurement teams, selecting the right latching relay requires careful evaluation of current rating, contact resistance, endurance, temperature performance, mechanical integration, and production consistency. A reliable latching relay solution can contribute to lower meter power consumption, improved long-term reliability, and more efficient smart grid infrastructure.
