Circuit Breakers are safety devices designed to protect electrical systems and components from damage due to overloads, short circuits, or ground faults. The UTS400N-FTU-350A-3P-LL-UL is a three-pole, fast-acting, high-interrupting-capacity circuit breaker designed for residential, commercial and industrial applications.

The UTS400N-FTU-350A-3P-LL-UL circuit breaker has several key features that make it suitable for a variety of applications. It is UL listed, meaning it meets the safety requirements of Underwriters Laboratories for a wide range of applications. It is rated for 350 amperes at a voltage of 120/240V, making it suitable for most residential, commercial, and industrial applications. It features a “Fast Trip” design that allows it to trip at high current levels in a fraction of a second, protecting against dangerous overloads and shorts.

One of the main benefits of using the UTS400N-FTU-350A-3P-LL-UL is its fast-acting response time. The breaker will trip and quickly break the circuit if the current exceeds its rating and prevents dangerous electrical overloads or shorts. The circuit breaker also features a UL listing, making it suitable for use in a wide range of applications, including residential, commercial, or industrial applications.

The UTS400N-FTU-350A-3P-LL-UL also features a resilient, non-metallic design. This allows the breaker to resist damage from dust, dirt, and other contaminants. It also helps protect against corrosion and ensures a long life span. Additionally, the circuit breaker has a lockout feature, which makes it easy to reset the breaker after it trips.

The working principle behind the UTS400N-FTU-350A-3P-LL-UL involves the use of an electromechanical trip technique. The breaker contains a bimetallic strip that is designed to expand and trip at a certain temperature. When the current in the circuit reaches the rated amount, the strip will expand due to increased heat generated by the current. The expansion of the strip will cause the contacts to open, breaking the circuit.

In summary, the UTS400N-FTU-350A-3P-LL-UL is a three-pole, fast-acting, high-interrupting-capacity circuit breaker designed for residential, commercial, and industrial applications. It is UL listed and rated for 350 amperes at 120/240V. It features a fast trip design, a resilient non-metallic design, and a lockout feature. It uses an electromechanical trip technique involving the use of a bimetallic strip to open the circuit when the current exceeds the rated amount.
