Circuit Breakers

A circuit breaker is a specialized type of switch that is designed to safely and reliably interrupt an electrical circuit to protect against overcurrent and short circuit faults. Circuit breakers are used to protect both individuals from electrical shock and wiring and equipment from excessive current. Circuit breakers also provide protection from problems such as overloads, short circuits, and ground faults.

The 209-2-1-53F-2-9-75-H Circuit Breaker is a three-pole molded case circuit breaker designed for use in low voltage (240/480V) industrial, commercial, and institutional applications. It is certified to UL489 standard, which enables the breaker to interrupt high fault levels and provide over-current protection. The primary function of the 209-2-1-53F-2-9-75-H circuit breaker is to automatically detect and interrupt the flow of current in an electrical circuit in the event of an overload, short circuit, or ground fault.

The 209-2-1-53F-2-9-75-H circuit breaker utilizes a vacuum interrupter as its primary switching device. The vacuum interrupter is a sealed metal can with a pair of electrodes located inside. When the breaker trips, a pair of contacts inside the interrupter open and the current flowing through the circuit is interrupted. This prevents the circuit from sustaining overcurrents and short circuits, which could cause electrical fires or power outages.

The 209-2-1-53F-2-9-75-H breaker also features a thermal-magnetic trip mechanism. This mechanism detects when the current exceeds the breaker\'s rated current, which trips the breaker and interrupts the current. This helps protect against overcurrents and protects the wiring and equipment from damage due to excessive current. The trip mechanism can be adjusted to provide an increased level of protection from overcurrents.

The 209-2-1-53F-2-9-75-H Circuit Breaker is a cost-effective solution for industrial, commercial, and institutional applications. It is UL tested and comes with a UL489 certificate, which provides assurance that it meets the most rigorous safety requirements. It provides superior protection from overcurrents, short circuits, and ground faults, ensuring safety and reliability.
