Pk-12 is a relay protection system developed by EA01, designed for medium voltage switchgear and electrical transformers. The system is equipped with two protection modules, namely EA01-2PK-12 and EA01-3PK-12, for the 6-12kV low voltage applications.The EA01-2PK-12 is a non-powered device which utilizes the thermal, magnetic or direct break. It is a low cost and reliable solution for low voltage applications. The device is characterized by its minimal complexity, easy installation, and good protection features.The EA01-2PK-12 is based on two thermal elements and a direct break. The first thermal element, known as the primary thermostat, is responsible for the initial temperature protection. It uses a thermistor to detect any changes in the current or voltage and trip the breaker. If the current or voltage exceeds the set values, the primary thermostat will activate the starter and switch off the device.The second thermal element, known as the secondary thermostat, is used for additional protection. This thermostat detects any changes in the current or voltage and triggers a trip if the current or voltage exceeds a preset limit.The direct break in EA01-2PK-12 is designed to be earthed during normal operation and is operated in accordance with the safety standards. This break is designed to disconnect the power supply in case of an overload, high voltage, or any other abnormal condition.In addition, the EA01-2PK-12 is designed with an additional feature which allows it to switch off the current by overvoltage protection. This feature monitors the voltage and if the voltage exceeds a certain limit, the circuit breaker will automatically trip to avoid any damage to the equipment.The EA01-2PK-12 device is widely used in various electrical applications such as distribution boards, industrial control systems, and renewable energy systems. It is also used in transformers for providing protection against reverse power flow and other electrical faults.In conclusion, the EA01-2PK-12 is a reliable low voltage protection system which provides a good level of protection against various electrical maladies. It is very cost-effective, easy to install and maintain. This makes it an ideal choice for low voltage applications.
