LEG66-39142-20-V Circuit Protection

A circuit breaker is a vital piece of equipment for preventing electrical accidents in homes and businesses alike. The LEG66-39142-20-V is a compact single pole thermal magnetic circuit breaker that is typically used in residential and commercial applications. It is rated to break resistive and slightly inductive loads at 20A and 240VAC and offers efficient over-current protection.

The LEG66-39142-20-V circuit breaker is equipped with a sensitive thermal element and a magnetic trip mechanism that can detect overloads or short circuits. The thermal element is designed to detect low-level overloads and automatically trips when a certain overload threshold is reached. The thermal element also serves to reset the circuit breaker after a power outage.

The thermal element works in combination with a magnetic trip mechanism that generally provides faster protection for larger overloads or short circuits. The magnetic trip mechanism will trip the circuit breaker quickly and reliably if the current exceeds the rated interrupting capacity.

Installation of the LEG66-39142-20-V circuit breaker is straightforward and requires minimal effort. The breaker is equipped with two-pole terminals that accept 4-gauge to 14-gauge stranded copper wire. The circuit breaker can be inserted directly into a compatible circuit breaker circuit panel or onto a backplate. Once installed, the circuit breaker can be enabled or disabled using either a manual toggle switch or a dimmer switch.

The LEG66-39142-20-V circuit breaker offers numerous advantages over other circuit protection devices. It is designed to protect tamper-resistant wiring, reduce fault-currents, and withstand the effects of rapid cycling. Additionally, this circuit breaker has fast trip times for quick interruption of overloads and short circuits, improved dielectric properties, and superior arc-quenching characteristics.

In conclusion, the LEG66-39142-20-V is a compact and reliable single pole thermal magnetic circuit breaker that is designed for both residential and commercial applications. It is equipped with a combination of a sensitive thermal element and a magnetic trip mechanism that provide excellent protection from overloads and short circuits. Installation of the circuit breaker is straightforward, and it offers numerous advantages over other circuit protection devices.
