APPLICATION GUIDE
Residual-current monitoring
The sensing transformer, relay and trip arrangement form a system. Determine the required response and coordination with other protection. A leakage monitor should not be assumed to provide the same function as a complete protective switching device.
Typical applications: Distribution and machinery circuits needing leakage supervision.

Key selection checks: Sensor compatibility; trip arrangement; selectivity.
Discuss earth leakage relays ↗Common questions
Does the listed range mean every option is in stock?
No. The range describes selected catalogue families. NPE confirms the exact series, configuration, stock and lead time against your enquiry.
Can I replace a component using its headline rating alone?
No. Check the full electrical duty, physical fit, interfaces and supported accessories. Send the installed reference so the intended function can be compared against the proposed component.
