UTE100E-FTU-15-3P-LL-UL

Circuit breakers are a common form of protection in both residential and industrial applications. These devices provide a convenient way to manage current interruptions and prevent damage to electrical systems. The UTE100E-FTU-15-3P-LL-UL is a type of circuit breaker specifically designed for use in low voltage installations. This article will discuss the application field and working principle of this device.

Application Field

The UTE100E-FTU-15-3P-LL-UL is suitable for use in residential, commercial, and industrial settings. It can be used to protect small lighting circuits, single-phase motors, household appliances, and other similar loads. This circuit breaker is a three-pole type, with a maximum rated current of up to 15 amps. The UL listing ensures that this device meets or exceeds the standards of the American National Standards Institute (ANSI) and Underwriters Laboratories (UL). This circuit breaker is designed to offer protection against over-currents and short circuits.

Working Principle

The working principle of the UTE100E-FTU-15-3P-LL-UL is similar to that of other circuit breakers. When the device senses an over-current or short circuit, it will open the circuit in order to protect the components connected to it. This is done by the use of a pair of contacts, which open and close according to the amount of current passing through them. These contacts are made from a metal alloy, which will resist heat and provide good electrical conductivity. If a short circuit occurs, the metal alloy will become heated and cause the contacts to open and thus interrupt the current.

The UTE100E-FTU-15-3P-LL-UL also includes a thermal tripping device. This device is designed to measure the temperature of the contacts and detect when a short circuit has occurred. If a short circuit is detected, the device will open the contacts of the circuit breaker and disconnect the circuit.

The UTE100E-FTU-15-3P-LL-UL circuit breaker provides a convenient way to protect electrical systems. Its robust construction and UL listing make it suitable for a wide variety of residential, commercial, and industrial applications. This device is easy to install and provides reliable protection against over-currents and short circuits.
