A circuit breaker is a device used in electrical systems to protect against over-current and short-circuit conditions. The R21-62-2.00A-29263-3-V circuit breaker is designed for residential and commercial use, offering reliable protection and compliance to UL 489 and UL 1077 standards. It is rated for 230/400V AC, 50/60Hz and offers two trip settings, positive and negative. The circuit breaker also features a shunt trip indicator, a manual override, an undervoltage release, an overload reset switch, and an adjustable time delay feature.

The main components of a circuit breaker are the tripping mechanism, trip bar, and contacts. The tripping mechanism is responsible for sensing when an over-current or short-circuit condition occurs and triggering the breaker to trip. The trip bar is a rod that connects the contacts to the tripping mechanism and is responsible for physically opening the contacts when the breaker trips. The contacts are in charge of making and breaking the electrical connection between the power source and the load.

The R21-62-2.00A-29263-3-V circuit breaker works in three steps: sensing, triggering, and breaking. Sensing is where the tripping mechanism of the breaker detects an over-current or short-circuit condition. Once detected, the tripping mechanism triggers the breaker to trip. This is done by the trip bar, which physically opens the contacts. Lastly, the contacts break the electrical connection between the power source and the load, resulting in the breaker tripping.

The R21-62-2.00A-29263-3-V circuit breaker is designed to provide reliable protection and to meet UL 489 and UL 1077 standards. It is well suited for residential and commercial applications and offers a number of advanced features, such as adjustable time delay, manual override, overload reset switch, shunt trip indicator, and undervoltage release. It is rated for 230/400V AC, 50/60Hz and is a great option for protecting circuits and ensuring safe and reliable operation.
