Circuit breakers are devices that monitor, open and close electric circuits for a variety of purposes. In general, these devices are activated when an overload or short circuit condition is present. These systems are designed to protect against overcurrent and overvoltage conditions, and to protect people and property from potential harm caused by an electric shock. These devices are available in a number of different types, such as thermal, magnetic, electromagnetic and gas. The IEGH 66-33717-5-V Circuit Breaker is a type of breaker specifically designed for use in industrial control applications.

The IEGH 66-33717-5-V is a 3-pole, high interrupting capacity, thermal-magnetic circuit breaker. This device is rated for 277/480V AC and has an interrupting capacity of 18kA. It is designed to provide reliable operation and a long life by using an innovative patented design. The IEGH 66-33717-5-V is UL 489 listed, meaning it meets strict safety criteria and has been tested to ensure its safety.

The main application of the IEGH 66-33717-5-V is in industrial control circuits and to protect motors and other devices from overloads or short circuits. It is designed for use in applications with a high degree of continuity and where interrupting current flows are expected. This device can also be used for protection against direct lightning strikes and short circuits.

The IEGH 66-33717-5-V Circuit Breaker is a thermal-magnetic device which combines the thermal tripping mechanism and current transformer sensing in one device. It generally operates in one of two states: in the off-state, it is free to break the circuit, and in the on-state, it protects the circuit from overcurrent and short circuit conditions.

The working principle behind the IEGH 66-33717-5-V involves two components, a thermal tripping mechanism and a current transformer sensing. The thermal tripping mechanism works by detecting the presence of heat generated by an overload or a short circuit. When this heat reaches a predetermined level, the breaker trips, thus breaking the circuit. The current transformer sensing works by measuring the current in the circuit and relaying this information to the breaker. If the current exceeds a preset limit, the breaker trips, thus breaking the circuit.

The IEGH 66-33717-5-V Circuit Breaker is an effective way to protect electrical equipment from overloads and short circuits. It is a reliable and durable device with a long life. It is UL 489 listed, meaning it meets strict safety criteria, and it has been tested to ensure its safety. The IEGH 66-33717-5-V is ideal for industrial control applications where high current flows are expected and a high degree of continuity is desired.
