Tengen DZL25 series leakage circuit breaker

DZL25 series leakage circuit breaker is suitable forcircuit of AC 50Hz, rated working voltage 380V and rated cu rrent 100A, to make indirect contact protection to the human being, also to prevent fire accident caused by ground fault current due to the damage of insulation of equipment. In addition, it not only can protect the circuit and motor against overload and short circuit, but also can be used to switch the circuit and start the motor infrequently. The products are in conformity with such standards as GB 6829, GB 14048.2, IEC 60755 and IEC 60947.

This series of leakage breakers is current operated electronic earth leakage protector. The main components are composed of main switches, over-current tripping devices, zero sequence current transformers, electronic amplification circuits, leakage tripping devices, test devices and so on.

The overcurrent protection section is a hydraulic electromagnetic release (100A and below) and a thermal bimetal electromagnetic release (200A). Under normal circumstances, the current vector across the zero sequence current transformer is zero, and the zero sequence current transformer has no output on the two side, and the main switch remains closed to maintain normal power supply.

When the circuit is in the protection of the occurrence of leakage and electric shock when the primary side current vector through the zero sequence current transformer and is not equal to zero, the two will be the zero sequence current transformer produces an output current through the electronic amplifying circuit to make the action leakage tripping device, open the main switch, the circuit is cut off, cut off the power supply objective, to protect them.

Ordinary working conditions and installing conditions

1. The temperature maximum rate around the device should not be over +40°C, the minimum temperature should not be lower than -5°C, and the average temperature in 24h should not be higher than +35°C.

Note1: when the working condition has the minimum temperature -10°C to, customer should declare to manufacturer when ordering the device.

Note2: when maximum temperature is over +40°C or minimum is lower than -25°C in working condition, customer should consult the factory.

2. The altitude of the place where the machine be installed in should not be higher than 2000 meters.

3. The relative humidity of atmosphere should not be above 50% when the surrounding temperature is +40°C. It is allowed to work in comparatively high relative humidity when the temperature is comparatively low. For instance, when the relative humidity reaches 90% in +20°C, user should take some appropriate treatments to get rid of the occasionally appeared moist.

4. Class of pollution: Class 3

5. Category of installation: Category 3

6. Any field direction of the external field of the installation site should not be 5 times above what geomagnetic field has.

7. Generally, the breaker should be installed vertically. The upward direction of the switch handle represents the power is on. No matter what direction the switch handle points to, the deviation degree is allowed to be up to 2°.

8. There should not be obvious collision and vibration in or near installation position.
