High Power 3-phase 120A 150A Latch Changeover Latching Relay 24v
Notes:Magnetic Latching relays can have either single or dual coils. On a single coil device, the relay will operate in one direction
when power is applied with one polarity, and will reset when the polarity is reversed. On a dual coil device, when polarized
voltage is applied to the reset coil the contacts will transition. AC controlled magnetic latch relays have single coils that
employ steering diodes to differentiate between operate and reset commands.

3.1. Suggestions of relay’s input
(1) Polarity-Please check the polarity inside of our technical specification, if single coil then”+ -” or “- +”are fine, you can change it by one pulse.
If double coil then it‘s necessary to confirm “-+-” or “+-+“before leaving the our factory.
(2) Driving-Please energize the relay at our recommend pulse width, rated voltage for reliable performance,
if 1.5 time or 2 times of value or lower driving condition plz confirm with our engineer.
(3) Relays’contact status may be changed during transportation or installation due to impact of external force, therefore please reset to the required status.
3.2 Suggestions of relay’s output
(1) When choosing the relay with hard connection,please avoid the external force on load terminals during or after the installation.
(2) When the relay will be connected with screw or bolts to the relays’ terminals,
plz make sure your connection is fastened and prevent relay from damages or other safety problems due to temp. Rise..
(3) The sampling signal wires of products are limited, please do not pull or torque during installation.

6.Relay Knowledge- Latching relay
Latching relay is really a generic term that is used to describe the type of relay that maintains its position after the power is removed.
The reason latching relays are used is because they allow control of a circuit by providing a single pulse to a relay control circuit.
