R21-1-7.00A-W102EV

Circuit breakers, such as the R21-1-7.00A-W102EV, are an important element of electrical systems. They are designed to protect both personnel and the service panel from a short circuit or an overload. The purpose of a circuit breaker is to prevent an excessive current from flowing through an electrical system and to isolate certain systems from one another, thus preventing safety and operational hazards from occurring.

The working principle of a circuit breaker can be broken down into two parts: the mechanical switching of the breaker, and the electrical protection of the circuit. When an overload or a short circuit is sensed, the breaker is triggered. This triggers the mechanical switching action, which physically disengages the circuit from the panel and isolates it from the system. At the same time, an electrical circuit is opened and the current flow is stopped.

Circuit breakers are commonly used in residential, commercial, and industrial applications, such as on service panels, gas appliances, and major power lines. They are also often used in electrical systems that include safety features, such as emergency lighting and motors that are used to protect personnel and equipment. Circuit breakers can also be used with specialized applications, such as the over-current protection in photocopiers and other sensitive equipment.

The R21-1-7.00A-W102EV circuit breaker is a two-pole, dual-function breaker specifically designed for residential use. It features an adjustable trip switch and can be adjusted to trip in the event of an overload or a short circuit. The breaker also includes a manual reset, allowing it to be reset after protection actuation. Additionally, the breaker has a current rating of 7.00A and is rated for voltage up to 120/240 Volts.

The R21-1-7.00A-W102EV circuit breaker is designed for protection and safety in residential applications, but can also be used in light commercial applications. It is a reliable and cost-effective way of protecting home and business electrical systems from short circuits, power surges, and overloads. The breaker can be installed quickly and safely, and can provide reliable protection for many years.
