Introduction to Circuit Breakers

A circuit breaker is a safety device that disconnects an electrical circuit when it detects a short circuit or an overload condition. It is a critical part of any electrical system and its primary purpose is to prevent the electrical system from being overloaded or shorted out, which could lead to electrical fires or other dangerous situations. Circuit breakers come in a variety of shapes and sizes, but all of them are designed with the same goal in mind - to protect electrical equipment and circuits from unsafe currents.

R21-61-10.0A-R01CV-V Application Field and Working Principle

The R21-61-10.0A-R01CV-V is a circuit breaker designed to protect electrical circuits from the dangers of excessive current, overloads, and short circuits. It is typically used in industrial, commercial, and residential settings to protect electrical equipment and wiring from overcurrent conditions. The circuit breaker works by reacting to currents traveling through the circuit and then breaking the connection if the current exceeds the rated current for a certain period of time.

These circuit breakers are designed to trip off when any of the following conditions occur: short circuit (when excessive current flows due to a short in the electrical wiring); overloading (when the current demand on the circuit exceeds its rating); or arc-run-on (when damage to the circuit or wiring has caused excessive current to pass through the wires). The R21-61-10.0A-R01CV-V has a rated current of 10 Amps, which means that it will trip off if the current exceeds 10 Amps by a certain period of time.

The R21-61-10.0A-R01CV-V circuit breaker also has a temperature rating of -25°to +60°C. This is important as the higher the temperature of the circuit breaker, the more prone it is to tripping off due to overloads or short circuits. Therefore, this temperature rating helps to ensure that the circuit breaker can safely operate in a wide range of temperatures, making it a highly reliable breaker.

In addition, this circuit breaker also features a high-speed break-make mechanism, which means it can react quickly to short circuit or overload conditions. This benefit is particularly important in industrial settings, where an overload or short circuit can occur unexpectedly and cause severe damage. The fast response time of the R21-61-10.0A-R01CV-V helps to prevent damage before it can occur.

The R21-61-10.0A-R01CV-V is UL listed, meaning it has been tested and approved to meet the safety standards set by the Underwriters Laboratories (UL) international standards organization. This, along with the temperature rating and high-speed response mechanism, makes the R21-61-10.0A-R01CV-V a highly reliable and effective circuit breaker. It is designed to withstand a wide range of conditions and reliably protect circuits, making it an ideal choice for industrial, commercial, and residential settings.
