4420.0336 Circuit Protection

Circuit Breakers are commonly used in home appliances and industrial systems for electrical protection. The 4420.0336 is a typical circuit breaker specifically designed to protect components and systems from surges caused by instantaneous electrical faults. As a Surge Protective Device (SPD), the breaker reduces the severity of transient voltage by tripping before a damaging current reaches sensitive equipment.

Because of the critical role that circuit breakers have in protecting electrical equipment and power systems, it is important that they are designed with precise specifications to meet the needs of the application. The 4420.0336 has specific features that make it suitable for a variety of applications.

Application Field: The 4420.0336 is designed for use in residential, commercial, and industrial applications. It can be used to protect both high-voltage and low-voltage circuits. The breaker is rated for 240-Volt AC circuits, up to 1,000 Amps, and is UL tested and certified for use in common electronic devices such as computers, TVs and HVAC systems.

Working Principle: The 4420.0336 circuit breaker is designed to protect against electrical surges and shorts caused by momentary voltage spikes. It works by monitoring electrical current flow. When the current level reaches a pre-set trip point, either due to an electrical surge or a short, the breaker trips into the off position and interrupts power flow.

The circuit breaker is designed with a variety of control and protection features to ensure safe, reliable operation. It has a two-stage operating system, with a main thermal-magnetic trip unit and a frequency-sensitive element in the form of a bypass circuit. The thermal-magnetic trip unit monitors voltage and current levels to trip in the event of an over-current or short-circuit condition. The frequency-sensitive element utilizes an RC circuit to detect transient voltage spikes of high frequency.

The 4420.0336 also includes a built-in LED status indicator that displays the breaker’s current status – green for active, yellow for testing, and red for tripped. It features manual reset and can be reset either from the breaker or remotely using an external switch. It is also equipped with an adjustable toggle switch that allows for setting the trip level on the breaker.

The 4420.0336 is a reliable and cost-effective circuit breaker for protecting sensitive components and systems from transient voltage. It is easy to install and provides superior protection against sharp voltage spikes. With its adjustable settings and status indicator, it is an ideal solution for a wide variety of applications.
