Circuit breakers are essential components used to protect electric circuits by disconnecting them when a fault is detected. According to the NEC, there are three common types of circuit breakers; traditional circuit breakers, ground fault circuit interrupters (GFCIs) and arc fault circuit interrupters (AFCIs). Today we will be looking at one type of circuit breaker, the UPL11-5227-1.

The UPL11-5227-1 is a miniature adjustable overload protector designed to protect circuits from excessive current draw. It is an used to protect electrical circuits against thermal overload. It is a cost-effective and reliable solution for applications with stringent space-to-power requirements. It has adjustable current set points and a wide range of contact configurations.

The working principle of the UPL11-5227-1 is fairly simple. When the current reaches the preset current limit, a thermal bimetallic strip inside the device acts like a switch and terminates the circuit. The strip is designed for a specific trigger temperature, and when the temperature reaches that threshold it bends and creates a gap in the contacts and breaks the circuit. Once the current stops, the bimetallic strip cools down and the contacts reconnect, allowing the circuit to be restored.

The UPL11-5227-1 is suitable for a range of applications, including industrial electronics, motor control, audio/visual equipment and HVAC systems. It can be installed in any type of panel or enclosure, allowing for ease of installation and use. It can be used with both AC and DC applications and can be adjusted to whatever current setting is required for the application. The UPL11-5227-1 is also designed to be shock and vibration resistant, and operates over a wide temperature range.

In conclusion, the UPL11-5227-1 is a cost-effective and reliable way to protect your circuits from thermal overload. It is adjustable and can be used in any type of panel or enclosure. It is designed for a wide range of applications, including industrial electronics, motor control, audio/visual equipment and HVAC systems. The UPL11-5227-1 works by using a bimetallic strip to detect when the current reaches the preset limit and then shuts off the circuit. Its ability to withstand shock and vibration ensure that it will provide long-term protection for your equipment.
