CB221-30 Circuit Breakers are an increasingly important part of today’s electrical systems. Circuit breakers provide a safe and efficient means of protecting electrical circuits, equipment, and personnel in the event of a power outage or overload.
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current, usually resulting from an overload or short circuit. Its basic function is to detect a fault condition and immediately disconnect the faulty circuit from the rest of the electrical system.
CB221-30 circuit breakers are used in applications such as industrial, commercial and residential buildings. They are also used in motor control circuits, street lighting, HVAC systems, and in critical applications, such as fire alarms, communication networks and DC power systems.
The CB221-30 circuit breaker comes in three different configurations. The standard configuration includes one pole with an adjustable trip unit. The double-break configuration includes two poles with individual trip units and the thermal-magnetic configuration includes one pole with both a thermal and a magnetic trip unit.
The CB221-30 circuit breaker is capable of tripping on both overloads and short circuits. It has a built-in overload protection feature that prevents the circuit breaker from tripping when there is an overload, but still allows it to trip quickly when a short circuit or other dangerous condition occurs.
The CB221-30 circuit breaker also has an adjustable current rating. This rating can be adjusted by a turning knob on the front. This allows the user to set the current rating to the desired level while protecting the circuit from overloads.
In addition to providing overload protection, the CB221-30 circuit breaker also offers surge protection. This feature is provided by built-in thermal and dynamic memories which store data from prior events and helps it differentiate between short circuits and abnormal loading conditions.
The working principle of the CB221-30 circuit breaker is simple. When an overload or short circuit occurs, the circuit breaker senses the increased current flow, and trips to open the circuit, interrupting the flow of power and protecting the device from further damage.
The CB221-30 circuit breaker is a safe, reliable, and cost-effective method of providing overload and short circuit protection for electrical circuits and equipment. It is designed to provide maximum current interruption without creating an expensive arc flash hazard, and its adjustable current rating makes it an ideal solution for many applications.
