Circuit breakers are safety switches that are used to protect electrical systems and components from damage when an overload or fault current occurs. The 4230-T120-K0CU-8A breaker is a 3-pole, high-current interrupter designed for residential, commercial, and industrial applications. This article will discuss the application field and working principle of the 4230-T120-K0CU-8A circuit breaker.

The 4230-T120-K0CU-8A breaker has an interrupting capacity of up to 50,000 amperes at 480 Vac. It is designed for quick response and reliable protection for large residential, commercial, and industrial applications. This breaker can also be used in circuit layouts that require multiple connections in order to provide redundancy and maximum safety. Its UL listed construction also provides a high degree of electrical insulation.

The 4230-T120-K0CU-8A breaker features a NEMATRIP™ protection system which provides enhanced trip performance. This protection system consists of an electronic version of a thermal-magnetic device which senses current, provides overload protection, identifies short-circuit conditions, and trips at precisely the right time. This ensures that the breaker properly and quickly disconnects the circuit before too much current can be drawn, thus protecting the connected load from damage or destruction.

The 4230-T120-K0CU-8A breaker also carries a CSA-NRTL listing, which provides inspectors with a literal snap-shot of the circuit breaker’s UL rating. This can provide assurance that the breaker meets the requirements of the governing safety code.

In operation, the 4230-T120-K0CU-8A breaker works in the same way as other thermal-magnetic circuit breakers. When the current flow through the breaker exceeds the design current rating of the breaker, the device trips and interrupts the current flow. This helps to reduce the risk of damage to connected electrical equipment and circuits caused by over-current problems. The NEMATRIP™ protection system of the 4230-T120-K0CU-8A provides added reliability and safety by ensuring that the breaker can detect when the current rises above its design limit and quickly open the circuit to prevent damage.

In summary, the 4230-T120-K0CU-8A breaker is a reliable and safe device which is designed for large residential, commercial, and industrial applications. It features a UL listed construction and a NEMATRIP™ protection system which provides enhanced trip performance, helping to protect connected loads from damage or destruction. This breaker can be used in virtually any circuit layout, and it carries a CSA-NRTL listing, providing inspectors with assurance that the breaker meets the requirements of the governing safety code.
