>ZJ20 Series AC Contactor

General

ZJ20 series AC contactor (hereinafter referred to as contactor), mainly used for AC 50Hz (or 60Hz), rated working voltage to 660V.Rated current to 630A circuit for remote connection and breaking circuit, and can be combined with the appropriate thermal overload relay.to protect circuits that may operate over load. Standard: GB14048.5, IEC60947-5-1.

Type Designation

Working Conditions

1. Ambient air humidity is-5℃~+40℃ , and the mean value within 24 hours does not exceed +30℃.

2. Altitude: no more than 2000m.

3. Atmospheric conditions: the relative humidity of air is not more than 50% at the highest temperature of +40℃ ; high relative humidity can be allowed at lower temperatures, such as 90% at 20. Special measures should be taken for the occasional condensation caused by temperature changes.

4, pollution grade: Level 3.

5. Install class: III class.

6. Installation conditions: the inclination of the installation surface to the vertical plane is not greater than 5 degrees.

7. Impact vibration: products should be installed and used in areas without significant shaking, impact and vibration.

Main Parameters And Technical Performance

1. Coil rated power supply voltage Us: AC 58Hz, 110V, 127V, 220V, 380V; DC: 110V, 220V

2. mechanical life: ZJ20-10, 16, 25, 40, 63, 100, 160 are 10 million times, ZJ20-250, 400, 630 are 6 million times.

3. The saving rate of electricity saving products (see Table 1).

4 Main parameters and performance metrics contact (see Table 2).

5 Contact type auxiliary contacts, and the number of basic parameters (see Table 3).

Structural features

The contact system of the contactor is a direct-acting, double-breakpoint arrangement.

The ZJ20-40A and above auxiliary contacts are mounted as separate components on both sides of the main contact and are electrically separated.

ZJ20-10~25A products can be installed by screws or 35mm standard rails.

ZJ20-10~16A products use double breakpoints to simply break the arc extinguishing chamber, and the rest use plastic grid arc extinguishing cover, which has high breaking capacity and reliability. The advantage of high sex.

ZJ20-63~630 power-saving products have DC general-purpose power-saving modules, which

can not only derive noise-absorbing energy-saving products or DC-operated products, but also

do not occupy Auxiliary contacts, which greatly improve the reliability and longevity of road products.
