Circuit breakers are devices that protect electrical circuits by cutting off the power when an excessive current is running through them. The 1C40UL is a type of circuit breaker that is designed to protect residential, commercial and industrial applications. This article will discuss the 1C40UL application field and working principle.

The 1C40UL is an adjustable-trip circuit breaker that is ideal for use in homes, businesses and industrial settings. It is available in single poletrip designs and its adjustable trip can be set to trip at any chosen current setting. The 1C40UL is UL1077 listed and meets UL 489 requirements. It has been tested and certified by Underwriters Laboratories (UL) for use in residential and commercial applications up to 24 VDC, and in industrial applications up to 30 VDC.

In terms of application field, the 1C40UL can be used to protect appliances, lighting fixtures, motors, pumps and other electrical components. It is also commonly used in air conditioning and heating equipment, furnaces and water heaters. The 1C40UL can also be used for protecting connections in hazardous locations such as factories, garages and outbuildings. It is designed to provide overload and short-circuit protection for circuits of up to 240 volts.

In terms of working principle, the 1C40UL is a thermal-magnetic circuit breaker that operates on a thermal-magnetic principle. The breaker trips when the current running through it exceeds the predetermined setting. The trip current setting is adjustable and can be adjusted manually or remotely. When the current exceeds the set trip current, the thermal element in the breaker heats up and eventually trips the breaker. The magnetic element of the breaker also works to trip the breaker when a short-circuit or ground fault occurs. The magnetic element trips the breaker immediately, while the thermal element takes some time to trip it.

Overall, the 1C40UL is a very reliable and versatile circuit breaker that is perfect for protecting circuits in residential, commercial and industrial applications. It is easy to install and provides overload and short-circuit protection for up to 240 volts. The adjustable-trip feature of the 1C40UL allows users to set their own trip setting for different levels of current protection. Additionally, it meets the requirements of UL 489 and is UL1077 listed, making it a safe and reliable choice for a circuit breaker.
