The starter is mainly equipped with QX, QY type submersible pumps to start and protect switches. It is equipped with a thermal relay and a release release device, which can effectively protect the submersible pump from overload, single-phase operation, and long-term low voltage operation. It is also suitable for electric agricultural machinery, textile, cement, mining, port machinery and general machinery as an electric motor protection switch.
This manual describes the QZ610 series motor protection starter, which is equipped with a thermal relay and a split‑coil release mechanism to protect diving pumps and other motors from overload, single‑phase operation, and prolonged low‑voltage conditions. It outlines the starter’s construction, sealing, and environmental limits.
The document includes wiring diagrams, installation steps, adjustment of the thermal relay, safety precautions, and a detailed fault‑diagnosis table to help users set up, operate, and maintain the starter safely. This manual is written in Chinese.
| Operating temperature range | -30 °C to +40 °C |
|---|---|
| Maximum altitude | 1000 m |
The starter can be used at altitudes up to 1000 meters.
Use copper insulated wires with a cross‑section of at least 2.5 mm².
The fuse rating should be 3–3.5 times the motor’s rated current, typically 2.5–3 times for normal load.
