Circuit breakers are an important component in the operator’s safety systems. They are responsible for cutting off the electrical supply when a fault occurs in the electrical system. The 219-4-26959-5 is a type of circuit breaker, specifically used in three-phase systems.

Principally, the 219-4-26959-5 can be used in industrial, commercial, and residential locations. Depending on the power capacity and application, different models are available for each application. For example, if you need a device for a high-powered system, such as a substation, you would require an industrial model. Likewise, for domestic systems, you won’t require such a high powered model – a residential model would be more suitable.

The working principle of the 219-4-26959-5 is straightforward and simple. When a short circuit occurs on the power line, the current is effectively disconnected by the breaker. It works by using thermal and/or magnetic forces to separate the contacts that are connected to the electricity supply line. When the current exceeds the rated level, the trip time heats up the operating coil and magnet, causing the trip contacts to open and separate.

The two methods by which a trip break can be initiated are by a thermal trip and a magnetic trip. In a thermal trip, the contacts are opened when the current flow reaches its overload or short-circuit limit. The heating of the coil causes it to expand. When the operating temperature levels reach a certain point, the breaker trips and disconnects the current.

In comparison, for a magnetic trip, a current-sensitive magnetic field reacts to the increase in current and causes the contacts to open. Since the current level is monitored instead of the temperature, magnetic trips can detect smaller current overloads and short-circuiting.

The 219-4-26959-5 is an efficient and important circuit breaker in three-phase applications. It is used to disconnect electrical power in case of an overload or short circuit on the power lines, protecting both the device and the operator from an electrical fault. Its operation and working principle are simple, consisting of two types of trips: a thermal trip and a magnetic trip. The device is available for different power capacities and applications, making it suitable for both commercial and residential establishments.
