Blue Sea Systems 5063 Heavy Duty In-Line AGC/MDL Fuse Holder

Blue Sea Systems Heavy-Duty AGC/MDL In-Line Fuse Holder

The Blue Sea Systems 5063 (Catalog SKU 5063-BSS) is a marine-grade heavy-duty in-line fuse holder engineered to accommodate standard 1/4" * 1-1/4" (6.3 mm * 32 mm) AGC and MDL glass tube fuses. Designed for primary branch power protection, electronics installation, and auxiliary equipment runs, it provides a simple, reliable solution for fusing low-to-medium amperage DC circuits up to 30Amperes.

Constructed with a heavy-gauge #12 AWG tinned copper wire lead, the 5063 minimizes voltage drop while offering high resistance to corrosion and wire strands wicking moisture in harsh marine conditions. The flame-retardant molded body features a protective moisture-resistant snap cap to shield internal brass contacts from direct water spray, dirt, and salt condensation.

Key Features

• 30A High-Current Capacity: Integrated #12 AWG wire leads support continuous load currents up to 30 Amperes.

• Marine-Grade Tinned Copper Wire: High-strand 105°C insulated tinned wire resists corrosion caused by moisture and salt air.

• Universal 1/4" * 1-1/4" Glass Fuse Fitment: Fits standard AGC (fast-blow) and MDL (slow-blow) glass cartridge fuses.

• Protective Waterproof Cap: Integrated vinyl/rubber sealing cap protects internal fuse housing from dirt, dust, and water spray.

• High-Retention Spring Contacts: Brass contact clips maintain tight mechanical pressure on fuse endcaps to prevent micro-arcing under severe boat vibration.
