Circuit Breakers

A circuit breaker is a type of switch that plays an important role of protecting electrical circuits from possible damage caused by overcurrent, short circuits, and other faults. Circuit breakers can be used to control and protect all sorts of electrical equipment in homes, businesses, and industrial settings. The type of circuit breaker, known as a 219-3-36891-20 breaker, is designed to protect motors and highly inductive loads from possible damage due to high inrush currents. It is used in many types of applications, including those that require fast acting switching, higher fault current ratings, and compensation for circuits with high inrush currents.

Application Field

The 219-3-36891-20 circuit breaker is used in a variety of different applications, with motors being the main use for the breaker. It is used in many applications that require fast actuators, including automotive, industrial, material handling, food processing, HVAC, packaging, and electrical distribution systems. Some applications for this type of breaker include pumps, blowers, fans, mixers, compressors, conveyors, grinders, and any other type of motor application with high starting current requirements.

The breaker can also be used in other non-motor applications. It can be used in any type of application that requires fast reactions and a high level of fault current. This includes applications such as lighting, surge protection, UPS systems, elevated temperature circuits, and other applications where a high fault current and fast response time is needed.

Working Principle

The 219-3-36891-20 breaker is a fast-acting, non-adjustable type of circuit breaker. The breaker is designed to trip in a few milliseconds in response to a fault condition. It also has an internal system that compensates for high inrush currents and adjusts the pickup setting accordingly. When the current exceeds the breaker’s rated pickup current, it will trip and disconnect the circuit.

The breaker uses a thermal-magnetic trip device to respond to current overloads and short circuits. The thermal element is designed to sense the overload and trip the breaker in a few milliseconds. The magnetic element is used to sense and respond to short circuits. When the short circuit current is high enough, the magnetic element will trip the breaker in a few cycles. Together, the thermal and magnetic elements work together to quickly and reliably protect the circuit.

The breaker also features an adjustable timer. This adjustable timer allows the breaker to be used in applications with high inrush currents. The breaker can be adjusted to compensate for the inrush current and still respond quickly to a fault condition. This allows the breaker to protect the circuit and motors but still have a reasonable amount of time before the breaker trips.

Conclusion

The 219-3-36891-20 circuit breaker is a fast-acting, non-adjustable breaker that can be used to protect motors and other electrical equipment from potential damage from overcurrent, short circuits, and other faults. The breaker uses a thermal-magnetic trip device, adjustable timer, and internal system to compensate for high inrush current to quickly and reliably protect the circuit. This type of circuit breaker can be used for a variety of applications, including motors, lighting, surge protection, UPS systems, and even elevated temperature circuits.
