Circuit breakers are designed to cut off any excess electrical supply when it becomes overloaded. As technology has developed, so has the sophistication of these devices, leading to the 219-3-5401-2 which offer superior performance for both commercial and residential applications.

The 219-3-5401-2 is a 3P circuit breaker, meaning it has three poles, used in applications with three-phase electrical systems. They are designed to protect from electrical overloading and short circuiting within electrical networks containing up to 480 volts AC. Additionally, they feature adjustable trip settings for optimal control over its operation and have a UL 489 rated short circuit current rating (SCCR) to provide safe, secure, and reliable protection of electrical systems.

These circuit breakers use thermal-magnetic trip units which perform functions of both thermal and magnetic elements. The thermal element on the 219-3-5401-2 uses a bimetallic current sensing element that responds to the heat generated by excessive current and shuts down the circuit. The magnetic element acts as a supplementary trip, monitoring any type of abnormally-high current that could cause overloads before the thermal element kicks in. The two working together ensure that the circuit can handle any short term surges and be effectively shut down, keeping both people and components safe.

This circuit breaker also features an IP30 housing that can resist water ingress, making it ideal for both indoor and outdoor applications. It also has a wide operating temperature range, making it suitable for applications in temperatures ranging from -25°C to +70°C. Additionally, its standard connectors make it easy to connect to other components.

The 219-3-5401-2 makes it easy for installers and maintainers to quickly identify and rectify any issue that could arise. Its clear trip indicators on its front panel help to identify when the trip breaker has been triggered, so any corrective action can be taken. If the breaker remains tripped and there is an installation fault or other issue at play, there is also the option to manually reset the breaker.
