ITC-104D-4/0AWG 4 Port Dual Insulated Connector Block | 250 MCM – 6 AWG
P/N: ITC-104D-4/0AWG
This 4-port 250MCM insulated connector block features a dual-rated aluminum body, a high-dielectric plastisol outer coating, and a 250MCM to 6 AWG wire compatibility range.
Rated for 600V and pre-filled with oxide-inhibitor gel, this compact 4.03-inch terminal block provides a safe, tape-free splicing solution for heavy-gauge copper and aluminum conductors inside control cabinets and junction boxes.
Key Features & Benefits
- Bi-Metallic Splicing Adaptability
This dual-rated insulated connector block seamlessly supports aluminum-to-copper, aluminum-to-aluminum, and copper-to-copper wiring configurations. The heavy-duty bi-metallic interface prevents galvanic corrosion when joining dissimilar conductors in high-amp industrial panels.
- Oxide-Inhibitor Internal Lubricant
Internal wire ports are pre-filled with oxide-inhibitor gel to prevent contact oxidation and ensure reliable electrical conductivity. This moisture-resistant lubricating compound seals the wire entry points to maximize terminal lifespan in damp outdoor enclosures.
- High-Voltage Plastisol Shielding
A heavy-duty UV-resistant plastisol coating provides high-dielectric insulation to eliminate the need for manual tape wrapping. This rugged protective outer cover resists chemical exposure, impact, and extreme temperature ranges from -49°F to 194°F.
- Heavy-Gauge Wire Capacity
The four-port terminal block accommodates thick power cables ranging from 250MCM down to 6 AWG. Secure 5/16-inch hex head bolts deliver massive clamping torque to guarantee stable, low-resistance 600V connections.
- Compact Cabinet Layout
The compact 4.03″ x 2.19″ profile fits easily inside crowded breaker sub-panels, junction boxes, and industrial distribution boards. This space-saving electrical splice block replaces bulky traditional split-bolts to simplify organized panel layouts.
