The UPG12-22477-2 is a circuit breaker designed for use in panel boards, switchboards, and motor control centers. This type of circuit breaker has an interrupting capacity of 12 kAIC, suitable for 600-volt applications. The breaker is typically used in circuits rated from 20 to 125 amps, and comes in a single, double, or triple pole configuration.

The UPG12-22477-2 circuit breaker is designed with a magnetic trip unit that senses current levels and automatically trips to protect the circuit from overloads or short circuits. The trip unit consists of a coil and a magnet core, which form a current-dependent coil inductance device that detects an increased level of current within the protected circuit. When the coil inductance reaches a given threshold, an internal contact opens, interrupting the flow of electricity.

The UPG12-22477-2 circuit breaker also includes thermal-magnetic protection. This type of protection employs a bimetallic strip that is heated by the current passing through it. When the temperature of the strip reaches a specified point, the strip deflects and trips the breaker. This type of protection adds an additional layer of safety against continued operation of the protected circuit with excessive current conditions.

The UPG12-22477-2 is designed to meet UL and CSA standards, providing peace of mind for those looking to install this type of circuit breaker. It is also easy to maintain and install, with features such as clear instruction labels, easy access to external trip settings, and an adjustable thermal-magnetic trip curve. Additionally, the breaker can be reset manually after a trip, allowing for a quick restoration of power in case of an emergency.

The UPG12-22477-2 is an ideal circuit breaker for protecting circuits in industrial and commercial applications. It is designed to provide reliable and robust protection against overloads, short circuits, and faults, helping to ensure the safe operation of electrical systems. With its easy installation, low maintenance requirements, and UL and CSA compliance, the UPG12-22477-2 is an ideal choice for many circuit protection needs.
