Speed Fuse 50LET Series Industrial Cartridge Fuse 500V Fast Acting Protection 1600A

Cartridge Fuse Model FWH400A 50LET Overview The FWH400A 50LET is a flat tubular cartridge fuse designed for voltage electrical protection. It provides fast fusing action for reliable short circuit interruption and circuit protection in mediumvolume installations where quick response and current handling are required. Key benefits Fastacting protection: Fusing speed rated F/fast reduces exposure to short circuit conditions and helps protect downstream equipment. voltage capability: Rated for up to 500 V, suitable for many industrial and commercial electrical systems. current capacity: Maximum current 1600 A with a holding current of 400 A, enabling use in demanding circuits and distribution networks. Simple, reliable form factor: Flat tubular design fits compatible cartridge fuse holders and simplifies replacement and maintenance. No reset required or expected: Automatic reset function is none, ensuring clear fault indication and safe manual inspection after operation. Important specifications Model: FWH400A 50LET Type: Cartridge fuse Size: 50LET Usage: Electricity Volume: Medium Voltage characteristics: voltage Shape: Flat tubular Fusing speed: F/fast (fastacting) Maximum voltage: 500 V Maximum current: 1600 A Holding current: 400 A Operating temperature: 0 C Temperature control range: 0 Automatic reset function: None Implementation standards: Not specified Function and compatibility Function: Interrupts excessive current quickly to protect wiring, switchgear, transformers, motors, and other equipment. Compatibility: Intended for use with holders and fuse blocks sized for flat tubular cartridge fuses and for electrical systems requiring the listed voltage and current ratings. Verify holder and panel clearance before installation. Performance and materials Fastacting fuse element for quick interruption of fault currents. Flat tubular profile supports stable seating in compatible cartridge holders. Rated values are intended to guide selection for proper system protection; select based on system voltage, prospective fault current, and coordination requirements. Typical applications Industrial distribution panels and switchboards where voltage, current protection is required. Motor control centers and feeder circuits that demand fastacting overcurrent protection. Backup power systems and power distribution in commercial facilities where reliable interruption and clear fault indication are needed. Installation notes Confirm fuse holder compatibility with flat tubular cartridge fuses of size 50LET before installation. Ensure system voltage does not exceed 500 V and that current handling matches circuit requirements. Because there is no automatic reset, inspect and the fuse after it operates to restore protection. This product is intended for use as specified above. Verify all parameters against system design requirements before selection and installation.
