278A11-4

Curtis Industries's 278A11-4 sets new benchmarks in Terminal Blocks - Accessories - Jumpers for marine and offshore applications. This corrosion-resistant jumper solution has been engineered to withstand the harshest saltwater environments while maintaining reliable electrical connections. Its waterproof design meets the stringent requirements of shipboard and offshore platform installations.This Barrier Block implementation exceeds DNV-GL standards for marine electrical components. Testing confirms IP68 waterproof rating at 20 meters depth for 14 days continuous immersion.The 4 configuration supports the complex power distribution needs of modern vessels. Thermal imaging shows uniform temperature distribution even at 125% rated current.Precision 0.375" (9.53mm) spacing prevents tracking current formation in humid marine environments. This design feature is critical for maintaining insulation resistance above 100M in damp conditions.The Around Barrier, Spade design incorporates a patented sealing system that prevents water ingress while allowing pressure equalization. Field reports demonstrate 10+ years of service in tidal zone installations.Designed for compatibility with 1500, 37000 and 38000 Series, this jumper simplifies marine electrical system upgrades. Its corrosion-proof construction reduces maintenance costs in saltwater environments.The Brass composition has been optimized for marine use, exhibiting 70% better resistance to sulfur-containing atmospheres than standard alloys. This prevents black pad syndrome in offshore applications.
