24V 5 Amp 5 Pin SPDT PCB Mount Relay 4KV Dielectric Withstand

SPDT Power Relay Description:
RJA series power relays are the ones that with small in size and lightweight, small current 5A, not only 4KV dielectric withstand voltage, but also meet with IEC60079-15 anti-explosion standard, safety system CQC/TUV/UL were approved as well, particularly useful in home appliances. 
 

Principle of Power Relay:
A power relay is a device that can produce a jump in one or more electrical output circuits when the input quantity (or excitation quantity) meets certain specified conditions. It can be used in the direct grounding system of the neutral point as a directional element for zero-sequence current protection.
The working principle of the power relay is that when a certain voltage or current is applied to both ends of the power relay coil, the magnetic flux generated by the coil passes through the magnetic circuit composed of the iron core, the yoke, the armature and the working air gap of the magnetic circuit. Under the action of the magnetic field, the armature Attract to the pole surface of the iron core, thereby pushing the normally closed contact of the contact to open, and the normally open contact to close; when the voltage or current at both ends of the coil is less than a certain value when the mechanical reaction force is greater than the electromagnetic suction force, the armature returns to the initial state, normally The open contact is disconnected and the normally closed contact is connected.

SPDT Power Relay Feature:
1. 1 form C,5pin
3. rated current 5A
3. class A insulation
4. dielectric withstands 4KV between coil and contact
