Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The Schneider Electric M9R81463 is a Multi9 GFP residual-current circuit breaker (RCCB) with four poles (4P), rated at 63 A with A-SI type earth-leakage detection at 30 mA. It forms part of the Multi9 modular protection range and functions as a dedicated ground-fault protector in electrical distribution panels. Typical applications include protection of industrial control panels, machine tool installations, and wet or polluted environments where humidity or aggressive agents are present. M9R81463 ensures personnel and equipment safety by rapidly detecting ground leakage.
Best Suited For
- Protection of control panels in humidity-prone or industrial wash-down environments
- Integration into OEM modular distribution boards for machinery
- Applications requiring A-SI type ground-fault detection (harmonic-rich environments)
- Use in 4-pole systems needing 30 mA residual-current protection
