Circuit breakers are designed to protect electrical systems from overloads and shorts circuits. The R21-62-30.0A-70441-7-T is a specialized type of circuit breaker that is used to protect electronic device components in the event of an electrical overload. This circuit breaker is designed to trip an electric motor in the event of abnormal current flow in order to protect the motor and surrounding components.

The R21-62-30.0A-70441-7-T is a single pole, 30A thermal circuit breaker that is UL Listed and RoHS compliant. This circuit breaker has a voltage rating of up to 125/220VAC and a temperature rating of -40 to +85°C. It is designed to be used with a variety of industrial applications, including machinery, HVAC, agricultural, and commercial equipment, as well as audio and lighting systems. This circuit breaker is ideal for use in applications that require long-life and cost-effective protection.

The working principle of the R21-62-30.0A-70441-7-T circuit breaker is simple: an internal thermal element senses a rise in temperature, caused by an excessive electrical current in the circuit. This element then triggers the circuit breaker to trip, which in turn de-energizes the circuit. There are two different types of tripping mechanisms, thermal and magnetic, both of which are highly effective in preventing overloads and potentially dangerous arcing or sparks.

In the case of thermal tripping, the circuit breaker has a thermal trip unit that senses an increase in temperature. This is usually caused by an excessive current flow in the circuit. As the thermal element reaches the preset temperature limit, the trip will be triggered and the circuit breaker trips. This type of circuit breaker is designed to trip before any damage to the protected circuit occurs. Magnetic tripping relies on a magnetically sensitive component that senses an excessive current flow and triggers a trip mechanism.

The R21-62-30.0A-70441-7-T circuit breaker provides important over-current protection of electronic and electrical equipment in both residential and commercial applications. Circuit breakers like the R21-62-30.0A-70441-7-T can offer safety and reliability at a cost-effective price. They are also highly reliable and have a long life expectancy, which makes them ideal for protecting sensitive electronic equipment.
