Design, development, the successful development of a new breaker, apply to the exchange of 50Hz, rated voltage 690V, rated voltage 400V and below, rated current 250A to 800A in the low voltage network.
Circuit breaker with equipped with intelligent tripper, not only increased the rated current range of choices, have overload long-delay inverse time, short-circuit short-delay inverse time, short-circuit instantaneous time limit in three sections protection, and long-time delay overload and short circuit short-time delay time can be set by the user.
In addition to the intelligent tripper circuit breaker with three sections of protection, and under voltage protection.
An electromagnetic tripping short circuit instantaneous characteristics of backup protection, making the product more safe and reliable.
Having five tripping characteristic: users can choose according to the load current of tripper for setting and adjustment; electronic tripping device by a circuit breaker to provide energy, current signal control and power from the mounted on the breaker inside the ring current transformer.
A warning indicator: when the circuit breaker is current through a load and normal operation, circuit breaker cover the LED indicator is green; when the load current exceeds a preset current value, the circuit breaker cover the light-emitting diode indicating yellow; when the load current exceeds two times the current setting value, the circuit breaker cover the LED indicator red.
Outline dimensions and TYM2 series plastic shell type circuit breaker with the same, mounting interchangeability.
Installation: installed vertically (i.e., vertical or horizontal installation. ) ( i.e. transverse mounting ).
This circuit breaker with IEC60947-1, GBl4048.2 standards.
Suitable conditions and installation conditions:
1 the location of the installation height of not more than 2000m;
2 ambient temperature less than +40℃ and not lower than -5 ℃, 24 hours average temperature of less than +35℃;
The 3 installation of the relative humidity in the highest temperature of +40 ℃when not more than 50%, the minimum temperature can have a higher relative humidity, the humidity monthly average lowest temperature of less than +25℃, the monthly average maximum relative humidity of not more than 90%, and consider due to temperature changes occurring on the surface of the product gel;
The 4 mounting site without the risk of explosion in the medium, and medium non-metal corrosion and damage to the insulation of gas and dust where conductive; no snow or rain;
5 pollution degree 3;
6 installation category III. |
