Circuit breakers are invaluable in modern electrical systems. By quickly disconnecting electrical circuits, they protect both the system and its users from dangerous overloads and electrical faults. The PR11-2-.400A-28591-1-V is a circuit breaker equipped with overload and short-circuit protection.

This circuit breaker is used for single-phase AC power distribution and is designed for use with both residential and light industrial applications. It can be used directly with electrical terminals and panelboards, and can be used as a sub-feed circuit breaker in larger, panelboard-style load centers. With a rated current of 400A, the PR11-2-.400A-28591-1-V is ideal for power distribution in large homesteads and small commercial premises.

The PR11-2-.400A-28591-1-V circuit breaker is designed to provide reliable and safe protection to both people and equipment. The device features integrated overload trip, short-circuit protection, adjustable trip current settings, and adjustable delay time settings. In the event of an overload or short-circuit, the PR11-2-.400A-28591-1-V is designed to trip, cutting off power to the circuit, and preventing the possibility of a fire or equipment damage.

The PR11-2-.400A-28591-1-V is designed for corrosion-resistance and simplified, low-maintenance installation in electrical applications. It features a 1.5” flange-mounting base, making it easy to install in panelboards or junction boxes. The trip indicator featuring a thermal-magnetic trip unit and a current adjustment range of 5-30A to ensure accurate and reliable protection against overloads and short-circuits.

The PR11-2-.400A-28591-1-V utilizes a thermal-magnetic trip unit that works in tandem with a thermal element and a magnetic trip element. In normal operation, current passes through the breaker, generating heat which is dissipated through the breaker\'s housing. If the current exceeds the trip current, the thermal element will function to open the circuit, before the magnetic element steps in to finish the job and protect against further damage.

The magnetic element works by sensing the current in the circuit, and creating a magnetic field around the breaker\'s core. If this current increases beyond a certain value, the magnetic field will interact with a trip bar in the breaker, causing it to open and disconnect the circuit. This ensures reliable protection against both overloads and short-circuits.

The PR11-2-.400A-28591-1-V is a dependable, highly efficient circuit breaker designed to meet the needs of residential and commercial applications. It utilizes a sophisticated thermal-magnetic trip unit to provide reliable and effective protection against both overloading and short-circuits. The device features a flange-mounting base for easy installation in panelboards or junction boxes, and adjustable trip current settings to ensure accurate protection.
