    Megger TSX-303 TRAX Automatic Switch Box overview | Fast & Safe Transformer Testing

    The Megger TSX-303 Automatic Switch Box is an essential accessory for transformer testers in high voltage substations and industrial applications. Designed to work with TRAX series analyzers, it lets you carry out winding resistance measurement (WRM), turns ratio tests (TTR), and demagnetisation on transformers up to three windings and eight terminals—without reconnecting leads between phases or taps. That means less time climbing ladders, fewer connection errors, and enhanced safety thanks to colour-coded bushing cables, soft carry-case, and built-in safety features.

    Megger TSX-303 Key Features

    • Single-connection testing: connect once and test all phases & taps automatically.
    • Uses eight colour-coded bushing cables (9 m) with Kelvin clamps & XLR connectors for quick and consistent setup.
    • Compatible with TRAX devices for WRM up to 16 A, TTR up to 250 V, plus demagnetisation workflows.
    • Soft compartmentalised carry-case included; option to choose a hard-case or banana-connector version for existing cable sets.
    • Important safety & convenience: fewer trips up/down ladders, less risk of incorrect connections, and built-in ground terminal and warning indicators.
