Something about Magnetic Latching Relay
Magnetic latching relay factory condition for contact closure state,but because carry or installed when subjected to impact,may change state,therefore before use to make its reset.
Several kinds of relay
Tongue spring relay: a relay that opens, closes or converts the line with tongue spring action that is sealed in the tube and has the dual role of electric shock reed and arbit magnetic circuit
Introduction of Relay
A relay is an electrical control device. It has a control system (also known as input loop) and a quilt The interaction between control systems (also known as output loops). Usually applied to the control of automation
Relay main product technical parameters
Refers to the minimum current that the relay can generate the draw action. In normal use, the given current must be slightly greater than the draw current for the relay to be stable To work. The working voltage added to the coil, generally do not exceed 1.5 times of the rated working voltage, otherwise it will produce a large current and burn the coil.
The relay coil is represented in the circuit by a long box symbol, and if the relay has two coils, two long boxes are drawn side by side. At the same time, mark the relay word symbol "J" in or beside the long box. There are two ways to represent the contacts of relays: one is to draw them directly on one side of the long box, which is more intuitive. The other is to draw each contact into its own control circuit according to the needs of the circuit connection. Usually, the contact of the same relay and the coil side are marked with the same text symbol, and the contact group is numbered to show the difference.
Self-locking and interlocking are achieved by auxiliary contacts of relays. First of all, you need to understand what is called self-locking and what is called interlocking. Self-locking is to short off the button switch of the contactor coil loop with your own contacts, and make the coil loop open continuously after the button switch is released, which is self-locking.
Parameters of double coil relays

Three Phase Magnetic Latching Relay
3 groups of 120A contact switching capability Contact on-off detection auxiliary switch can be provided Coil control single and double coil optional
When choosing a relay with QC lead-out method, please do not use soldering to connect the load lead-out end of the relay. If other welding methods are used, it is also necessary to ensure that the heat generated by welding will not affect the function of the magnetic latching relay
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.
