Circuit breakers are devices designed to detect and interrupt the flow of electricity when specific thresholds such as current or voltage are exceeded, which protects other electrical components in the system from damage from these overloaded conditions. The IEG12-31960-3-V, which belongs to the general circuit breaker family, is primarily used in medium voltage power distribution applications. In more detail, the IEG 12-31960-3-V is designed for the protection of motors, transformers and other medium-voltage equipment in power systems.

The IEG12-31960-3-V is a medium-voltage three-pole-operated vacuum circuit breaker, which is designed and manufactured in compliance with IEC 62271-100 and IEC 62271-100-1. It is suitable for breaking and making normal load current, fault current and short-circuit current on electricity networks with a rated voltage of 12kV and a rated frequency of 50Hz. In addition, the circuit breaker can facilitate breaking and making currents with a powerful short-time current of up to 100kA.

The IEG12-31960-3-V is equipped with an M frame mechanism with set speeds of mechanical motions and an excellent distance of travel. As a result, it can ensure that contact and arcing can only be completed when the main contacts are closed after the arc-extinction chamberhas completed its re-ignition process. This allows the circuit breaker to interruption short-circuit currents with high short-circuit power.

The IEG12-31960-3-V has a mechanism which is triggered with an external power source, and is driven by the moving contacts themselves. The device is equipped with a pilot relay which helps control the armature in order to reduce the interruption time of the breaker. This mechanism helps to ensure that the breaker’s contact system can be closed without causing damage to other electrical components in the system.

The IEG12-31960-3-V also features a built-in electric monitoring system which helps prevent circuit overloads and reduces maintenance costs. This device is equipped with a number of sensors including a power factor meter, current coil, voltage coil, and other relays. Furthermore, its connection box makes it easy to install and connect the device to existing electrical systems.

Overall, the IEG12-31960-3-V is a medium-voltage three-pole-operated vacuum circuit breaker which is designed for the protection of motors, transformers, and other medium-voltage equipment in power systems. Its built-in monitoring system ensures that the device is safe to use as it can detect and interrupt the flow of electricity when specific thresholds are exceeded. In addition, the IEG12-31960-3-V features a mechanism which is triggered with an external power source, and a pilot relay which helps to reduce the interruption time of the breaker. It is easy to install and incorporates a number of sensors for detecting potential circuit overloads making it an ideal choice for medium voltage power distribution applications.
