The Electronic Thermal Relay Calibrator from Wuhan GDMK Electric Co., Ltd. is a three-phase current generator designed to simulate load conditions for testing thermal overload relays and motor protection devices. It outputs 0 to 500 amperes per phase simultaneously, enabling synchronized testing of trip times across multiple contacts. The unit includes built-in detection for normally open and normally closed relay contacts.
The device is constructed for industrial environments, with a rugged chassis and thermal management to handle continuous operation at high currents. Output stability is maintained within ±1.5% of set value under standard ambient conditions (20°C to 30°C). It supports series connection of multiple units to increase current capacity, a feature common in utility and railway testing facilities where high-current relay banks are evaluated.
This calibrator is used by power utilities, railway maintenance depots, petrochemical plants, and mining operations for preventive maintenance of motor control centers. Buyers typically require the unit for compliance with IEC 60255-8 and IEEE C37.112 standards. Orders are shipped in steel crates with lifting points. Packaging includes manuals in English and Chinese. Lead time and MOQ are not listed; buyers must request details directly.
