Circuit breakers are typically used to protect electrical wiring and equipment from sudden power surges for safety purpose. IUG111-1-66-4.00-21 is a type of circuit breaker operating on the principle of thermal-magnetic. It is designed for medium-voltage or low voltage industrial applications, such as motors, fans, compressors, pumps, heating and ventilation systems, and other similar AC electrical loads.

Thermal-magnetic circuit breakers are a combination of two control features: a thermal Overload Relay and a magnetic short-circuit protection device. The thermal element is connected in series with the protected circuit and is designed to respond to the heat generated by the long-term overloading of the load, while the magnetic element is connected directly to the phase and neutral conductor and is designed to respond to the instantaneous surge in current caused by a short circuit or ground fault.

The operating principle of IUG111-1-66-4.00-21 circuit breaker is based on the characteristics of current in an electrical system. There are two basic currents that can appear in an electrical system; these are the rated current and the short-circuit or ground fault current. The rated current is the average current that the circuit breaker is designed to carry while the short-circuit or ground fault current is the maximum current that can flow through the circuit breaker in the event of a short-circuit or ground fault. The IUG111-1-66-4.00-21 circuit breaker is designed to detect a short-circuit or ground fault by comparing the two currents and if the short-circuit or ground fault current exceeds the rated current, the breaker will trip and break the circuit.In addition, the IUG111-1-66-4.00-21 circuit breaker is also designed to provide a measure of protection against overloads. Overloads occur when an excessive amount of current is drawn from the system, which can raise the temperature of the conductors and cause a fire hazard. The IUG111-1-66-4.00-21 circuit breaker is designed to detect the increase in current caused by the overload and automatically trip the breaker to protect the conductor from overheating.The other important feature of the IUG111-1-66-4.00-21 is its high rated current. The high rating allows the circuit breaker to handle heavy-duty applications and ensures a safe environment even in the event of a high level current surge. The high rated current also provides a layer of protection that prevents the circuit breaker from getting overloaded and burning out. Overall, the IUG111-1-66-4.00-21 circuit breaker is a reliable and efficient device that is designed to protect against sudden power surges, overloads, and short-circuits or ground faults. Its thermal-magnetic operation ensures that the circuit breaker will trip and break the circuit when it detects a dangerous current surge, thereby providing a safe environment for both electrical wiring and equipments.
