●overview
TYM1L series with residual current protection circuit breaker with plastic casing ( hereinafter referred to as the circuit breaker ), is the company adopts the international advanced design, manufacturing technology developed, developed a new type of breaker. Rated insulation voltage of 800V, apply to the exchange of 50Hz, rated voltage 400V, rated current to 630A circuits for infrequent switch and infrequent start of motor with. Circuit breaker with overload, short circuit and under voltage protection function, can protect the circuit and power supply equipment from being damaged, but also on the overcurrent protection can not detect the long-term existence of grounding fault may cause fire hazard protection.
Circuit breaker according to its rated ultimate short-circuit breaking capacity ( Icu ) level, classified as type M ( higher breaking type), H ( high breaking type) two class. The circuit breaker has the advantages of small volume, high arc breaking, short, vibration characteristics.
The circuit breaker may be mounted vertically ( i.e. arranged vertically ), can also be installed on the level (i.e., transverse mounting ).
The circuit breaker can not be poured into the line, which allowed only 1, 3, 5 power line, 2, 4, 6 are connected with a load line.
The circuit breaker products by performing the following standard:
IEC60947-1 and GBT14048.1 general
IEC60947-2 and GB14048.2 low voltage circuit breaker and appendix B with residual current protection circuit breaker
IEC60947-4 and GB14048.4 contactors and motor starters
IEC60947-5.1 and GB14048.5 electromechanical control circuit devices
Main characteristics
Conventional with residual current protection circuit breaker leakage protection module power supply to two-phase sampling, the series circuit breaker for three-phase lack, if any, circuit breaker leakage protection module can still work normally;
Rated current of I N and the largest opening time according to the actual situation field adjustable;
When the phase voltage is reduced to 50V, leakage protection module can still work normally;
With leakage alarm output function, can not only alarm tripping;
In line with the IEC60947 appendix B electromagnetic compatibility requirements;
The volume and shape of TYM1 series circuit breaker with the same specifications, installation has good interchangeability.
●suitable working conditions and installation conditions
The location of the installation elevation of 2000m and below;
Ambient temperature is not high and +40 ℃ and not lower than -5 ℃; and 24 hours on average no more than 35℃( with the exception of special order );
The installation place of air relative humidity on the highest temperature is 40 ℃does not exceed 50%; at lower temperatures can have 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 considering the temperature change occurs on the surface of the product gel;
Pollution grade 3;
Circuit breaker circuit installation category III, not connected to the main circuit auxiliary circuit and a control circuit, installation category ii;
Without the risk of explosion in the medium, and medium non-metal corrosion and damage to the insulation of gas and dust where conductive;
In the absence of snow or rain;
The circuit breaker should be according to the product manual installation. |
