12kV Three-Pole Indoor Isolator Switch & Earthing Switch for Switchgear
$190.00
Overview
Nelink indoor high voltage disconnector and earthing switch are three-pole AC 50Hz switching devices designed for 12kV indoor switchgear. The disconnector provides visible isolation point for circuit maintenance, while the earthing switch safely grounds the circuit after disconnection. Both types feature three-pole mechanical linkage, reliable contact and manual operating mechanism. Available in epoxy resin insulator or porcelain insulator versions. Compliant with GB and IEC standards, widely used in KYN28, XGN and other 12kV indoor metal-clad switchgear.
