  • Product Details

product name

Stepless enhanced contact relay: JWJXC-6800


Product Usage

The JWJXC-6800 type enhanced contact relay is used as a power supply supervisory relay for the electric point machine in the power supply screen of the small station.

The JWJXC2-6800 type enhanced contact relay is used in the distributed power supply screen.


Features

1. JWJXC-6800, JWJXC2-6800 type relays are DC 220V heavy elasticity reinforced contact electromagnetic relays, adopting the principle of "constant gravity" to force the moving and closing contacts to open when the coil is de-energized.

2. The use of silver-silver oxidation requires contacts, which has the characteristics of strong anti-adhesion and low contact resistance.

3. The magnetic circuit adopts electromagnetic pure iron material with small residual magnetism, and installs the stop piece at the closed position of the armature and the iron core to ensure the minimum air gap of the magnetic circuit, prevent the ferromagnetic parts of the magnetic circuit from magnetization, and ensure the reliable fall of the relay.

4. The magnetic circuit system is basically the same as the AX series of non-polar relays. The difference is the thickness of the armature stop piece to increase the release value and reduce the release time.

5. The contact system consists of two parts: ordinary contacts and reinforced contacts. There are two groups of moving-on and moving-break conversion ordinary contacts; two groups of moving-on and moving-break conversion reinforced contacts with arc-extinguishing magnets, the structure of ordinary contacts and infinite relays Similarly, the reinforced contacts are specially designed high-power contacts and arcing devices.
