This document describes pole‑mounted recloser controller complying with IEC 60255‑1:2022, IEC 60255‑26:2023, IEC 60255‑27:2023, with mechanical tests IEC 60255‑21‑1/2/3 and climatic tests IEC 60068‑2‑1/2, IEC 60068‑2‑78. It integrates phase overcurrent, earth‑fault, sensitive earth‑fault, negative‑sequence, frequency, synchronism‑check, cold‑load pickup and SOTF protection.
Time‑scheduled setting‑group auto‑switching and upstream‑downstream sequence‑coordination logic are available. Local LCD‑keypad HMI with optional RF remote controller. RS485/Ethernet interfaces support IEC60870‑5‑101/104, DNP3.0 and Modbus‑RTU.
Non‑volatile flash memory retains fault, SOE, energy and operation‑counter data after power loss. It applies to overhead‑distribution automation, loop‑networks and distributed‑generation interconnection.
