ANL‑A™ Fork Bolt Automobile DC Fuse
High‑Performance Bolt‑On DC Fuse for Automotive, RV, Marine, Solar & Heavy‑Duty Applications
1：Product Overview
ANL‑A fork‑bolt DC automotive fuse is a heavy‑duty bolt‑mount high‑current fuse engineered to comply with DIN 43560/1 industry specification. Optimized for demanding direct‑current overcurrent‑protection scenarios, this series is widely adopted for car‑audio power systems, off‑road vehicles, recreational campers, marine craft, battery‑energy‑storage units and construction machinery.
It features robust UL94‑V0 heat‑resistant thermoplastic housing with a visible melting‑element window for quick fault inspection. Terminals are manufactured from high‑conductivity copper‑alloy with tin‑plated finish. Dual M8 bolt mounting (60 mm centre‑to‑centre spacing) delivers stable high‑current connection under continuous vibration and harsh vehicle operating environments. The ANL‑A lineup covers current ratings from 30 A up to 600 A, supporting DC voltages 32 V, 80 V, 125 V and 150 V with breaking‑capacity up to 1000 A. All units are RoHS‑compliant for global market deployment.

6：Typical Applications
- High‑power car‑audio amplifier main‑circuit protection
- RV, camper and caravan battery‑bank DC protection
- Off‑road vehicles, heavy‑duty trucks & construction machinery
- Marine boat DC power‑distribution systems
- Off‑grid solar battery‑bank and compact energy‑storage equipment

7：Installation Guidelines
- Secure with M8 hardware, strictly apply mounting torque 12 Nm ± 1 Nm. Insufficient torque causes over‑heating and burnout; excessive torque may crack thermoplastic housing.
- Designed exclusively for DC circuits. Do not deploy on AC power systems.
- After fault events, inspect visible melting‑element window for quick on‑site diagnostics.
- Select fuse rating based on continuous operating load‑current of your protected circuit.
