Bussmann LPN-RK-40SP Dual Element Class RK1 Rejection Current-Limiting Time Delay Fuse 40 Amp 250 Volt AC 125 Volt DC Low-Peak™

SKU: 59466
Bussmann Low-Peak™ LPN-RK-SP Class RK1 Current limiting time delay fuse is rated at 40 Amps and 250 Volt AC/125 Volt DC. Interrupt current rating of this fuse is 300 Kilo-Amps at 250 Volt AC and 100 Kilo-Amps at 125 Volt DC. It offers current limitation to protect downstream components against damaging thermal and magnetic effects of short-circuit currents. This rejection fuse has ferrule terminal connection. It has dual element that provides the best time delay performance. Fuse has separate overload and short-circuit elements that provide time delay for close sizing of high-inrush loads linked with RK1 current limitation. Cylindrical fuse features melamine body construction. Insulated end caps reduce exposure to live parts. It ensures worry-free installation virtually in any application. It is perfect for large distribution switchboards, power panelboards, motor control centers, machinery disconnect switches, feeder/branch circuits, motors, transformers, solenoids and general-purpose circuits. Fuse is UL listed, CE marked and CSA certified.
  • Time-delay permits 130% FLA sizing for backup motor protection
  • Protects against 1-Phase motor damage
  • Proper sizing can provide No Damage Type 2 co-ordinated protection for NEMA and IEC® motor controllers
