Schnelle Sicherung RS39 RSM 1000 — fast-acting fuse for high-current protection. Available in 800 A, 1000 A, and 1250 A to match different load requirements. Key benefits Rapid interruption of fault currents to limit conductor and equipment damage. Selective protection that supports coordination and reduces unnecessary outages. Robust housing designed for demanding environments and reliable field service. Simple integration with RS39 RSM 1000 fuse holders and standard distribution boards for straightforward replacement and installation. Compact, modular format for use in space-constrained enclosures. Important attributes Function: Fast-acting overcurrent protection for high-current circuits. Compatibility: Direct fit with the RS39 RSM 1000 family and common mounting schemes in distribution panels. Size and format: Compact, modular design that eases installation where panel space is limited. Material and durability: Rugged construction using high-quality fuse components for consistent field performance. Performance: Reliable trip at or below rated current with consistent operation to ensure predictable protection. Typical applications Main feeder protection in manufacturing lines with heavy motors and intermittent high loads. Protection for distribution panels serving large loads in commercial facilities. Fast fault clearance in renewable energy inverters or large power supplies where rapid interruption reduces downstream risk. Selection note For existing RS39 RSM 1000 installations, choose the appropriate rating: 800 A, 1000 A, or 1250 A to provide precise protection for the specific load.
