88 Series Plastic Nut Resettable Manual Reset Overload Protector Thermal Motor Protection Circuit Breaker

88 series Circuit breakers (commonly known as overcurrent protectors) are suitable for AC 50/60Hz, rated working voltage up to 250 Va c, DC 32Vdc, rated current up to 30A for additional overload protection in the internal branch circuit of electrical equipment. The key part, the temperature sensing element is made of bimetallic material. It is not only a thermal sensor, but also an operating mechanism. It is accurate and reliable. It is widely used in various electromechanical appliances, such as: electric tools, power sockets, various generators, Electric motors (such as washing machines), uninterruptible power supplies (UPS), electric heating appliances, etc.

Table of Environmental Correction Factors

(Derating Factor)
-5°C
(3A-4A)×1.2, (5A-30A)×1.12
+40°C
(3A-4A)×0.92,(5A-30A)×0.94


The time current characteristic curve depends on the ambient temperature prevailing. In order to eliminate nuisance tripping. Please multiply the current brea ker current ratings by the derating factor shown below

Example:
Normal Continuous Current= 10A
Ambient Temperature = 45 °C
Multiplication Factor = 0.85
Recommended Rating=10A/0.85=11.8A
Select the Nea rest Rating = 12A
