Off-Circuit Tap Changer | De-Energized Transformer Tap Switch

Linear/series no-load tap switch for output voltage adjustment

HK$55.00

Overview

Off-circuit (de-energized) tap changers adjust the transformer turns ratio in steps (typically ±5%) to match local voltage, operated only while the transformer is isolated. Linear and series configurations cover single and three-phase designs.

Key Features

  • Adjust HV winding taps ±2x2.5% / ±5%

  • Silver-alloy contacts for stable low-resistance connection

  • Panel-mount or tank-cover mount with operating handle

  • Single and three-phase, linear and series types
