Product details
Eaton - Bussmann Electrical Division's TB400-04 redefines Terminal Blocks - Barrier Blocks standards for underwater robotics and subsea instrumentation. This pressure-compensated terminal block maintains perfect sealing at 6000m depths while resisting saltwater corrosion. Its oil-filled design and advanced polymer chemistry enable decades of reliable operation in ROV and AUV applications.The Barrier Block configuration provides hydrostatic pressure compensation without moving parts.With 4 pressure-balanced circuits, it supports complex sensor arrays on oceanographic equipment.The 8 penetrator design maintains IP68 rating at full ocean depth pressures.0.687" (17.45mm) marine-grade spacing prevents dendritic growth in long-term submerged applications.The 2 row layout optimizes pressure distribution across the housing.Rated for 75A in conductive seawater environments, it exceeds ABS underwater equipment standards.600V isolation prevents electrolysis in seawater power distribution systems.Compatible with 6-14 AWG marine cables, including oil-filled and gel-insulated types.The Screws system maintains gas-tight seals throughout thermal cycling.Closed interface provides strain relief for dynamic cable applications.2 Wall (Dual) barriers prevent cathodic disbondment in submerged metal structures.The Flange implementation addresses unique challenges in deep-sea electrical systems.The Black housing incorporates biofouling-resistant additives for long-term deployment.
