SACE Tmax XT Circuit Breaker Dielectric Test Guide

This document provides step-by-step procedures for performing dielectric (high-voltage) tests on the auxiliary and main circuits of SACE Tmax XT circuit breakers (models XT2, XT4, XT5). It includes critical safety warnings, instructions for disconnecting specific components (such as Ekip trip units, communication modules, and external cables), and notes on insulation resistance testing limitations.
