DW16 400V 690V Air Circuit Breaker


Application


DW16 Air Circuit Breaker is mainly used in the distribution networks of AC 400V/690V, 50Hz for power distribution, protecting the lines and equipments from overload, under voltage and short circuit. Besides, it can also be used for infrequent ON and OFF operations.

The rated current is up to 4000A.

Completed accessories is available.


The use of environmental conditions


Ambient temperature: -5 ~ 40 , daily average over 35 Altitude not more than 2000m;

Ambient conditions: relative humidity not more than 50% at 40, if lower temperature humidity can be higher, on the month when maxi average humidity occurs the Temperature shall be not more than 25 , on this month the maxi average humidity shall not more than 90%, and there has considered the mist covering the product Polluted class: 3 grade

Installation class: 3 grade

Mounting conditions: the mounting inclined angle shall not more than +5

Impact vibration: there shall have no severe vibration, impact and vibration.


Structure features

DW16 universal circuit breaker mainly consists of free tripping mechanism, contact system, overcurrent trip, arc-extinction system, etc.

1. Contact system, overcurrent trip are all mounted on the motherboard of the circuit breaker.

2. Contact system has arc-extinguishing system mounted on it, and has free tripping system connected with contact system through principle axis; on its left side there is auxiliary switch installed. Contact’s material is made of special alloy, which has excellent anti-fusion wielding capability and low contact resistance.

3. Arc-extinguish chamber grid plates are placed in parallel direction. The Arc-extinguish wall is made of arc tight plastic, and it has flash barrier accompanied with so that the circuit breaker’s short circuit breaking ability is improved.

4. This circuit breaker could also be installed operation like electric motor, lever, electro-magnet which only suits under 630A frame class current according to the need.
