1000mA Earth Leakage Circuit Breaker Tester
Product Overview
This MOEORW-WKL10 tester is a professional handheld device for verifying residual current device performance. It accurately measures tripping current, non-tripping current, and tripping time across single-phase two-wire, three-phase three-wire, and three-phase four-wire systems. With dedicated wiring diagrams and auto-step testing, it delivers reliable results for routine inspection and compliance verification.
