R21-2-12.0A-33168-1-V

Circuit breakers are devices that provide reliable short circuit and overcurrent protection for electrical systems. The R21-2-12.0A-33168-1-V circuit breaker is a low-voltage breakout device used in a wide variety of applications to prevent overloads or shorts on protected circuits.

The R21-2-12.0A-33168-1-V circuit breaker is classed as a residential type with a thermal or magnetic actuated operating mechanism. This device is ideal for multiple uses in residential electrical systems, such as in providing overcurrent protection for motors, lighting fixtures, air conditioners and similar circuits. The R21-2-12.0A-33168-1-V also works in a range of commercial and industrial environments.

This circuit breaker has a rated current of 12.0 Amperes, a rated voltage of 250 volts and a short circuit current rating of 10 kA. This device has a complete environmental rating of IP20 and is capable of breaking all types of common fault currents such as short circuit, overload and line to ground current.

The R21-2-12.0A-33168-1-V circuit breaker is designed with a thermal operating principle. The outer casing of the breaker is constructed of a flame-retardant, high impact plastic. This material resists heat build-up, outdoor conditions and has very good weathering ability.

The core of the breaker features three electromagnetic switches-a pair of thermal bimetal switches and one magnetic switch. When a short circuit occurs, the thermal bimetal switches operate first by sensing the temperature rise. This will cause the contacts to trip, thus breaking the circuit and preventing any further damage. The magnetic switch then follows and will remain closed until the current returns to a safe level and the breaker can reset itself.

The R21-2-12.0A-33168-1-V circuit breaker also features a number of specialized features. The breaker features an \'external manual operator\' so that the device can be manually reset in the event that it trips, and it also features a \'power on indicator\' which will let you know at a glance if the breaker is operational. This device is UL listed and has gone through a range of testing to ensure it will perform to the highest standards.

The R21-2-12.0A-33168-1-V circuit breaker is a reliable device, designed to provide excellent protection for a variety of residential, commercial, and industrial applications. With its excellent environmental rating, this device is a popular choice for protecting circuits from short circuits, overloads, and ground fault currents.
