The usage of electro-mechanical interlocking blockade PB ensure complete elimination of wrong connecting operations. Relay interacts with interlocking coil of the earthing switch, and blocking it if the voltage is indicated.
- Device can operate with many different capacitive insulators (from different manufacturers);
- The sensitiveness of the device can be calibrated. Acceptable output current form insulators: 20....500 mA;
- Voltages signaling independently for each phase by red LED diodes;
No external power is required, the necessary power comes directly from capacitive insulators; - Voltage detection system is independent from blocking system. (fault of the blocking system does not interrupt the functioning of the detection system);
- Device complies the requirements of the PN-EN 61958:2002 and IEC 61243-5;
- Three test sockets for external phase cooperation;
- Does not require maintenance;
- Dimensions: 110 mm / 77 mm / 97 mm;
- Protection level IP 40 or IP 45;
- There is a possibility to use the device as the measuring and executing module for power supply change over system base on APZmini. In this case PB has to be equipped with execution module
