4420.0689 Circuit Protection

Circuit breakers are devices used to protect electronic and electrical circuits from the damage and fire hazard caused by an overload of electricity. The 4420.0689 is one such circuit breaker. It is fitted with a sensitive relay designed to detect the level of electricity running through the circuit and reset itself in case of an overload. It also has a lever designed to trip the breaker in case of an emergency.

The 4420.0689 is a heavy-duty circuit breaker specifically designed for industrial applications. This particular model offers a current rating of up to 600 amps and a voltage rating of up to 600 volts. It is available in 1-pole, 2-pole, and 3-pole configurations. It also has a short-circuit rating of 10,000 amperes, making it suitable for use in high-intensity industrial environments.

The 4420.0689 works by using a sensitive current relay. When a current beyond its predefined threshold is detected in the circuit, the relay trips the breaker. This interrupts the flow of electricity, preventing the circuit from being overloaded. In addition, the lever allows manual tripping in the event of an emergency. The lever will manually force the trip bar up, disconnecting the circuit.

The 4420.0689 also features a quick-make, quick-break contact system for reliable operation. The structure of the breaker ensures reliable, secure operation. It is designed to be housed in a type 4X enclosure, allowing it to be installed in environments exposed to dust, water, oil, chemicals, and other harsh elements. The 4420.0689 also meets UL Safety Standards for Circuit breakers.

The 4420.0689 is a heavy-duty circuit breaker designed to provide reliable, secure protection for the most demanding industrial circuits. Its current, voltage, and short-circuit ratings make it ideal for use in high-intensity applications. The sensitive current relay and manual trip lever ensure safe operation under various circumstances. The quick-make, quick-break contact system ensures reliable operation in any scenario. The structure of the breaker is designed to meet UL Safety Standards and it can be housed in a type 4X enclosure, making it suitable for use in hazardous environments.
