R21-62F-.250A-26170-16-V

The R21-62F-.250A-26170-16-V is a circuit breaker that is falling into a special category known as molded case circuit breakers (MCCBs). This type of breaker has a variety of uses, with one of its main benefits being that it offers overload, short circuit and ground fault protection. 

MCCBs are generally employed in applications where there is a need to shut off circuit much more quickly than in the case of a standard circuit breaker. The R21-62F-.250A-26170-16-V utilizes a thermal-magnetic trip system that senses both heat and current. This is useful for protecting an electrical circuit from both overloads and power surges/faults. The R21-62F-.250A-26170-16-V also has a number of additional features, including an adjustable trip current and energy limit, which allow the breaker to be customized for specific applications.

The R21-62F-.250A-26170-16-V is designed for a range of industrial, commercial and residential applications. It is ideal for medium duty circuits and can handle currents from 10 amps up to 200 amps. The breaker can also be used in motor control applications because of its adjustable tripping features and high interrupting ratings.

The working principle of the R21-62F-.250A-26170-16-V is fairly simple. The breaker consists of a thermal and magnetic element that is used to monitor the current in a circuit and determine whether it has exceeded the maximum rating. If the current rises above the specified limit, the thermal and magnetic elements will trigger the breaker to open, shutting off the power. The magnetic element will detect high current surges over the normal current rating and will also be triggered if a fault occurs in the circuit.

Beyond providing overload, short circuit and ground fault protection, the R21-62F-.250A-26170-16-V also offers additional safety benefits. As it is a molded case circuit breaker, it is designed to prevent the unit from arcing or sparking if it is disconnected. This makes it ideal for use in areas where there is an increased risk of fire hazards.

Overall, the R21-62F-.250A-26170-16-V circuit breaker can provide electrical circuits with effective protection from overloads and short/ground faults. It is also highly reliable and safe, making it a popular choice for many applications. Whether you are looking for protection in your motor control system, residential building or industrial setting, the R21-62F-.250A-26170-16-V circuit breaker is a great option.
