This document introduces the features and characteristics of Xinling brand motor protectors, including the outline and installation dimensions, installation and adjustment steps, precautions, and ordering information.
This manual describes the Xinling HHD2D-1~6 series intelligent motor protector, which safeguards AC motors (50 Hz, up to 380 V) against phase loss, overload, imbalance, and stall conditions. The device uses current‑detection technology and a microcontroller for reliable, maintenance‑free protection.
The guide covers mounting options, wiring diagrams, parameter setting via the “整定电流” knob, indicator meanings, safety precautions, and ordering information. It also lists technical specifications such as rated current ranges, protection times, and power requirements. This manual is written in Chinese.
| Rated current range | 1 A–4 A, 2.5 A–10 A, 5 A–20 A, 10 A–40 A, 25 A–100 A, 40 A–200 A |
|---|---|
| Overload action time | ≤120 s (inverse‑time characteristic) |
| Phase‑loss action time | ≤5 s |
| Control circuit supply voltage | AC 220 V / AC 380 V, 50 Hz |
| Output load capacity | AC 380 V, 1 A (resistive) |
| Reset method | Power‑off reset, 60 ± 10 s reset time |
| Installation options | Device‑mount and 35 mm DIN‑rail compatible |
Turn the “整定电流” knob until its scale aligns with the motor’s rated current marked on the nameplate.
A green light indicates normal running, while a red light indicates a fault condition.
No, the output interface is a solid‑state AC switch and cannot be used with DC contactor devices.
The input current must not be less than 5 mA.
