88A Series Manual Reset Overload Protector Electric Push Button
Switch Circuit Breaker
88A series equipment circuit breakers (commonly known as
overcurrent protectors) are suitable for AC 50/60Hz, rated working
voltage to 250Vac, DC 32Vdc, rated current to 20A for additional
overload protection in the internal branch circuit of electrical
equipment, a key part of the product The temperature sensing
element is made of bimetallic materials. It is both a thermal
sensor and an operating mechanism. It is accurate and reliable in
action. It is widely used in various electromechanical appliances,
such as: electric tools, power sockets, various generators, motors
( Such as washing machine), uninterruptible power supply (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 breaker
current ratings by the derating
factor shown below.
Example :
Normal Continuous Current =10A
Ambient Temperature = 40°C
Multiplication Factor = 0.94
Recommended Rating=10A/0.94=10.6A
Select the Nearest Rating = 11A
Application
This product is widely used in household appliances (power sockets,
coffee machines, juice machines, vacuum cleaners, audio-visual
equipment, kitchen appliances, etc.), engines, air compressors,
electric vehicles, automobiles, power tools, UPS, large power
supplies, medical equipment, Major fields of circuit protection
such as mechanical motion and motors.
