Carlo Gavazzi GSB631PC20-Circuit Breaker

A circuit breaker is a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time.

Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, and automatically cut off circuits when they are severely overloaded, short-circuited, or under-voltage. Its function is equivalent to a fuse-type switch Combination with overheating and underheating relays, etc. Moreover, there is generally no need to change parts after breaking the fault current.

GSB631PC20 Description

Made by Carlo Gavazzi, GSB pro-mentary circuit protectors are available in 1, intended for over current 2, 3 and 4 pole configura-protection in applications, with amperage rating where branch circuit pro-up to 63A and voltage up to protection is already provided 480Y/277VAC.

GSB631PC20 Temperature Derating

The maximum permissible current in a supplementary protector depends on the ambient temperature and spacing between devices (see next paragraph). Ambient temperature is the temperature inside the enclosure or switch-board in which circuit breaker is installed. The reference temperature for nominal current rating is 30°C.
