JJJC3 AC enhanced contact relay

Product Usage

The JJJC3 AC enhanced contact relay is used as a power control relay in the power supply screen of the small station.

Applicable environment

Applicable environment The applicable environment of the relay is:

a) Ambient temperature: -40℃~+60℃;

b) Relative humidity: not more than 90% (temperature +25°C);

c) Air pressure: not less than 70kPa (equivalent to an altitude below 3000m);

d) Vibration: the vibration frequency is not more than 15Hz, and the amplitude is not more than 0.45mm;

e) Working position: horizontal;

f) There should be no harmful gas causing explosion hazard around, and good dust-proof measures should be taken.

Features

1. The relay is an AC 220V heavy spring force electromagnetic relay with reinforced contacts.

2. The relay magnetic system is a clap-on AC magnetic system, which is composed of an iron core, a coil and an armature.

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

4. The relay contact system consists of two parts: ordinary contacts and reinforced contacts. There are two groups of moving on and off ordinary contacts; the two groups of moving on and off reinforced contacts, the structure of the ordinary contacts is the same as that of the non-polar relay, and the reinforced contacts are specially designed large contacts. Power contacts.
