Circuit breakers are important devices in electrical system for protection against overload and short circuits.IUGBXF66-33038-30 is a type of circuit breaker which is designed for high current applications.

The rated current of the IUGBXF66-33038-30 circuit breaker ranges from 100A-400A, leaving enough margin for current surges, and it features a good breaking capacity of 30kA.The frame and operating mechanism of this breaker is integrated, and its controlled coil voltage is up to 690V. This type of circuit breaker can be used in four-phase power systems and in direct current systems with maxmium DC 400V.

The IUGBXF66-33038-30 circuit breaker is used for over-current and short circuit protection for three-phase AC power systems as well as for isolation of power cables and feeders. It is also used in switch gear applications where it functions as a device to open and close the circuit. This circuit breaker can be used in different power system applications such as substations and distribution networks, industrial, commercial and residential applications.

The main purpose of circuit breaker is to protect low voltage AC electrical systems from overload and short circuits.The working principle of the IUGBXF66-33038-30 circuit breaker is based on the thermal-magnetic effect.The thermal-magnetic effect ensures that the circuit breaker trips in the absence of any faults.During a normal working state, a cartridge heater inside the device slowly heats up the bi-metallic element.When the current passing through the circuit exceeds the rated current threshold, the current raises rapidly and trips the breaker.

The thermal-magnetic protection mechanism also works when- ever the current goes beyond the set threshold.The coil housed inside the device generates a magnetic field which causes the bi-metallic element to rapidly expand and trip the breaker.The circuit is switched off due to this trip, thus protecting the electrical system from overloads and short circuits.

In addition to that, the IUGBXF66-33038-30 circuit breaker has an adjustable instantaneous trip for over-current protection.This feature prevents electrical systems from damage due to high levels of current due to overloads.The adjustable setting of the overload protection helps to adjust the current tripping level as per the requirements of the particular application.

The IUGBXF66-33038-30 circuit breaker is a reliable and efficient protection device that can be used in a variety of applications.It has a rated current range of 100A-400A, a adjustable instantaneous trip and a high breaking capacity of 30kA.These features make it a suitable device for various power system applications such as switch gear, distribution networks and industrial applications.
