Littelfuse LJCA040.XP Low Profile Jcase Fuse 40A 58VDC

Product Description

The LITTELFUSE LJCA040.XP is a low-profile JCASE blade-style automotive fuse rated at 40 amps and 58 volts DC. It is designed to protect electrical circuits in commercial vehicles and passenger cars from overcurrent faults. The green color coding allows for quick amp-rating identification during inspection or replacement. The housing is constructed from PA66-GF13 glass-filled nylon for durability in underhood and panel-mount environments. Automotive electricians and fleet maintenance technicians install this fuse in fuse boxes and PDCs where space-saving low-profile components are required.

This fuse fits commercial vehicle and passenger car applications where the LP JCASE form factor is specified. It is commonly installed in blade-type fuse holders and power distribution centers that accept low-profile JCASE fuses. The 40A rating covers mid-range circuit protection loads such as blower motors, accessory circuits, and relay-controlled loads. This part is sold individually with a minimum order quantity of 5 units, making it appropriate for shop stock and fleet service operations.

Compatibility

Designed for commercial vehicle and passenger car electrical systems requiring an LP JCASE low-profile blade fuse at 40 amps and 58 VDC per ISO 8820-4 and SAE 2741 specifications.

Installation Notes

Installation should be performed by a qualified automotive or fleet electrician. Disconnect the vehicle battery before servicing any fuse panel or power distribution center to prevent arc faults and accidental circuit activation. Confirm the replacement fuse amp rating matches the circuit requirement exactly — never substitute a higher-rated fuse to address a repeatedly blown fuse condition. Diagnose the root overcurrent fault before installing the new fuse.
