Adapters

Most three phase equipment incorporates electronic circuitry such as temperature controls, PLCs which control relays, or motors which require starter circuits such as contactors. All of these types of controls, contactors and relays must be powered on to latch. Performing an insulation resistance test on such devices will only test up to the on/off switch and not show any faults inside the actual appliance. The ProTag TPL series three phase adaptors replace insulation testing adaptors by powering-up the three phase appliance and measuring the leakage current. The TPL Series also eliminate the need for less practical methods such as dismantling appliance plugs and using a clamp meter or using three phase cable adapters with an exposed earth. The TPL Series provide a safe way of testing three phase appliances, at all speeds and settings, whilst taking a quick and easy measurement on the LCD display.
