DCR-12-630 Outdoor Single Pole Isolator Switch

Rugged Isolation Solution for 12kV Overhead Power Lines

The DCR-12-630 is a pole-mounted single-pole Isolator switch rated for 12kV and 630A, engineered for manual disconnection and visible isolation in medium-voltage overhead systems. Its galvanized steel structure, UV-resistant insulators, and corrosion-proof components ensure high durability and safety, even in extreme weather.

This model is ideally suited for rural feeder segmentation, maintenance bypass, and emergency sectionalizing in utility distribution networks.

✅ Key Features

Visible Break Isolation – Air-gap contact ensures absolute safety for live-line technicians.
Weatherproof Construction – Designed for long-term outdoor exposure without performance loss.
Flexible Mounting Options – Compatible with concrete and wooden poles of various diameters.
IEC & ANSI Standards – Complies with IEC 62271-102 and ANSI C37.32 for global grid compatibility.
Low Maintenance – All moving parts pre-lubricated and protected against dust, corrosion, and thermal fatigue.
