RS PRO Mains Test Block
This three phase quicktest QT3 test power Connector is a compact, robust, power connector designed for temporary, safe and efficient connection of unterminated cables to 440Vac three-phase power supplies. The QT3 has a maximum rating of 16 amps.
The QT3 is designed for use in applications including manufacturing, test and repair, calibration, measurement, and anywhere a fast, safe and non-permanent connection to a three-phase power supply is required.
Connection to the Quickest takes just a few seconds. Simply open the lid, which automatically isolates the three phase supply, insert each bare cable end by pressing the five colour-coded piano key cable clips, and then close the lid to complete the circuit between the device being tested and the main electrical power supply. Opening the lid again isolates the supply source so the conductors can be rapidly removed.
