Overview
Prepare your enquiry
Stock reference 411664 is listed under: residual-current switch. Inventory designation markers: 4P; 25A; AC; 300MA. A residual-current switch monitors imbalance in circuit currents. Do not attribute a circuit breaker’s overload protection to it unless that additional function is explicitly documented.
A precise reference and a clear requirement help our team check your selection.
- Include quantities and the intended use.
- Describe existing equipment and interfaces to check.
- Specify the documents or technical details your project requires.
Applications
For a board with a designed residual-current protection and coordination scheme. Check pole count, rated current, detection type and sensitivity against the design. An inventory sensitivity value alone does not establish its application or selectivity.
