What is Circuit Breakers?

Circuit breakers are components designed to protect electrical systems and devices from potentially catastrophic damage, malfunctions, and short circuits. They are found in virtually all electrical systems and devices, and are the first line of defense against electrical inconsistencies and malfunctions. Electric circuits can often become overloaded, leading to sudden disruptions that can fry circuits and other electrical components. Circuit breakers are designed to detect these problems and shut off the power supply to the entire circuit before any major damage is done.

IEGH66-35090-2-V Application Field and Working Principle

The IEGH 66-35090-2-V circuit breaker is a reliable circuit protection device designed for use in panelboards, switchboards, motor control centers, and other applications. It is designed to meet the requirements of UL 489 for use in low-voltage systems. This circuit breaker features a single-pole, non-adjustable thermal and magnetic breaker with a manual trip, allowing for easy resetting once a fault is cleared.

The IEGH 66-35090-2-V features an integrated electronic trip module that provides selective fast or slow tripping of the breaker, helping to protect complex electrical systems from hazardous faults. The integrated trip module is protected from tampering and resetting by a tamper-resistant lock. In addition, the circuit breaker is rated for up to 1500 A short circuit current interrupting and up to 30kA interrupting current.

The IEGH 66-35090-2-V works by sensing short-circuits, overloads, and other abnormal conditions in the circuit and cutting off the power supply before any damage occurs. A thermal-magnetic trip element is used within the circuit breaker body to measure current and trip the breaker when it exceeds the trip settings. The thermal elements are designed to measure heat generated by the circuit and trip when it gets too hot, while the magnetic trip elements measure magnetic flux and trip when it exceeds the set level. The integrated electronic trip elements also sense current spikes and trip the breaker before it exceeds maximum levels.

The IEGH 66-35090-2-V is suitable for use in systems with grounding and can be used for common trip or single pole/breaker selectivity. With its sturdy, reliable construction and easy operation, the IEGH 66-35090-2-V is an ideal choice for circuit protection in many industrial, commercial, and residential applications.
