GMB631PC50

Circuit breakers are essential components in any electrical system. They are used to protect equipment from damage due to overloads and short circuits, by automatically disconnecting the power when the current exceeds a safe level. The GMB631PC50 is a type of molded case circuit breaker from General Electric. It is a 3-pole breaker rated for 480 volts, with current ratings up to 50 amps and interrupting ratings up to 10 kilo-amps.

The GMB631PC50 is suitable for general-purpose use in a variety of commercial and industrial applications. It is designed to provide high-performance protection in a wide range of conditions, with features such as adjustable trip settings and LED indicators to show when the breaker is tripped. It is also UL-classified, meaning it has been tested to meet safety requirements.

The GMB631PC50 has a manual override switch located on the side of the breaker, allowing it to be manually opened without the need to trip the breaker. This switch can also be manually engaged to trip the breaker, which is useful for testing and maintenance. The breaker is designed to allow for quick field replacement, and comes with mounting screws for easy installation.

The working principle of the GMB631PC50 is called inverse time short circuit tripping. In this type of concept, a current will cause the breaker to trip within an adjustable time, depending on the current magnitude. This allows the breaker to disconnect the power before damage can occur to the electrical system. The adjustable current range of the GMB631PC50 is adjustable from 0.4-6 Amps, with a trip time of 300 milliseconds (for currents up to 10 Amps) to 600 milliseconds (for currents over 10 Amps).

The GMB631PC50 is designed to provide reliable protection for electrical installations, with features such as adjustable trip settings, quick-release handles and easier mounting. It is a very popular choice for general-purpose use, and is suitable for a variety of commercial and industrial applications.
