Description
MITSUBISHI ELECTRIC NV-ZHA — Earth Leakage Relay ZHA Series, genuine MITSUBISHI ELECTRIC product.
Overview
The NV-ZHA is an earth leakage relay from Mitsubishi Electric that works with a separate zero-phase current transformer to detect leakage current in a circuit. When leakage exceeds the selected sensitivity, it outputs a trip or alarm signal to a breaker shunt trip or annunciator. Versions conforming to JIS and UL requirements are available for domestic and export panels.
Key Features
