The product performance is reliable, the protection characteristics of precision, breaking capacity, small size, nice, is the ideal replacement products.
Mainly used for AC 50Hz, rated voltage 230V / 400V, rated current to 125A power lines in the power facilities and electrical equipment over-current protection, can also be used for infrequent on-off work.
Normal working conditions
1. The ambient air temperature limit does not exceed 40 ºC, the lower limit of not less than -5 ºC. 24h the average temperature does not exceed 35 ºC.
2. The altitude of the installation site does not exceed 2000m.
3. The relative humidity of the installation site, at the maximum temperature of 40 ºC around the time not more than 50%, at a lower temperature can have a higher relative humidity. Special measures should be taken for occasional condensation due to temperature changes.
4. Pollution level 2.
5. Overvoltage category is 2 and 3 class.
6. The circuit breaker is mounted on a 35mm standard rail.
7. The circuit breaker should be mounted vertically and the handle is upwardly connected to the current position.
8. There should be no significant impact and vibration at the installation site.
Products using high-precision bimetallic material as anti-time thermal protection components, the protection characteristics of precision, the operating mechanism and then buckle reliable, contact system using double power series structure, double arc system, breakpoint voltage is low, in the case of high breaking capacity Under the current limiting characteristics. The product cleverly set the operating handle closing threshold, only the operating force reaches a certain value, in order to allow the contact quickly closed, so that the contact closed at a certain high speed, the relative exclusion of human factors on the contact closure speed, Reducing the electrical wear of the contacts when connected, and improving the life and reliability of the circuit breaker.
The product has a clear contact position status indication. Terminal block with lifting frame structure, wiring capacity of 2.5mm ²-50mm ².
Products can be used with shunt release, auxiliary contacts and other accessories.
