A circuit breaker is a safety device that wraps around an electrical conductor and triggers when there is a surge of current passing through the wire. The IEG66-29481-4-V is a type of circuit breaker that is designed to protect motors, heaters, and other pieces of machinery from overloads on their circuits. Although these breakers provide a measure of preventive maintenance for protectable systems, they can also be used in applications where no protection is needed.

The IEG66-29481-4-V circuit breaker is specifically designed for controlling low-voltage circuits. It is rated for 600 volts of alternating current (AC) such as those found in common household appliances, and can handle currents up to 600 amps. The breaker is mounted on a DIN-rail in standard electrical enclosures, and is available in multiple configurations to accommodate various system requirements.

The working principle of the IEG66-29481-4-V circuit breaker is quite simple. When a surge in current passes through the circuit, the breaker trips, cutting off power to the circuit and resetting itself in the process. The breaker has three main parts; a bi-metal strip, a switch, and a temperature sensitive thermal disconnect.

The bi-metal strip is designed to rapidly expand when it is heated. As current flows through a circuit, the bi-metal strip heats up. When the strip reaches its melting point, it expands, triggering the latch mechanism in the switch. The latch then pulls the switch open, cutting off the flow of current and resetting the breaker.

A temperature sensitive thermal disconnect is also built into the breaker for additional protection. If the voltage in the circuit exceeds the rated value for too long a period of time, the thermal disconnect will activate and also trip the breaker. This provides an additional level of safety, protecting components from being damaged from excessive heat.

In addition to the standard design, the IEG66-29481-4-V also offers several application-specific variants. For example, the V1000L-2S version is able to sense a drop in phase current and will reset itself accordingly. This allows it to be used in applications such as single-phase motor protection and phase-imbalance protection, where a drop in phase current indicates a problem.

The IEG66-29481-4-V is one of the most trusted and reliable circuit breakers on the market today. It is designed to protect equipment from over-current faults while ensuring safety and reliability. Its robust design and wide range of applications make it an ideal choice for industrial and residential applications alike.
