The DZ47LE residual current circuit breaker manual provides specifications, installation, operation, and maintenance instructions.
The DZ47LE series residual current circuit breakers are designed for AC 50 Hz systems with rated voltages of 220 V or 380 V and rated currents up to 32 A (63 A). They protect circuits from leakage currents, overloads, and short‑circuits and feature compact size, light weight, and easy operation.
The manual covers technical parameters, installation on a TH35 standard mounting rail, wiring diagrams, test procedures, safety warnings, and warranty information. It also explains how to perform periodic leakage‑current tests and how to maintain the device for reliable performance. This manual is written in Chinese.
