Circuit breakers are essential components of electrical power grids, ensuring safety in malfunctioning situations. As an integral part of the electric power system, they protect the system from overloads, short circuits, and other abnormal conditions. The APL11-21568-1 circuit breaker is an example of this technology used in many power grids across the world.

The APL11-21568-1 circuit breaker is a two-pole circuit breaker rated at up to 1000 volts with a rated current of 30-150A. The device has two modes of operation – thermal-magnetic trip function (TMTF) and auxiliary trip function (ATF). Under normal operating conditions, the magnetic trip function will be enabled, preventing significant current flow. When the current exceeds the rated value for a certain period of time, the thermal elements will kick in to open the circuit, breaking the circuit connection and preventing further current flow.

The auxiliary trip function (ATF) is another key feature of the APL11-21568-1 breaker. This feature enables additional protection in circuit breakers, allowing for the detection of overload conditions before they reach levels that would trigger the TMTF. The ATF can be configured to kick in at rated values of 5-90% of the set maximum current, helping to manage the current even before it crosses the normal operating threshold. This feature allows the breaker to respond more quickly to overloads, minimizing damage to the system and equipment.

In addition to the two operating modes, the APL11-21568-1 circuit breaker is also equipped with a wide range of features, including a humidity control range, a design-base current settings, and a temperature/humidity control system. These features add to the device’s accuracy and reliability, making it a great choice for industrial and commercial applications. The device is designed to operate in hostile environments, making it suitable for both indoor and outdoor applications.

The APL11-21568-1 circuit breaker is an essential component of the electrical power system, providing reliable protection of the circuits from abnormal conditions. It is important for people to remember to check and maintain their circuit breakers regularly, ensuring that they are functioning correctly and are in good condition. This will help to minimize damage to the system and equipment due to unexpected current surges or other malfunctioning conditions.
