ITC-104-3/0AWG 4 Port Insulated Connector Block | 3/0 AWG – 6 AWG
Part#ITC-104-3/0AWG
This 4-port insulated connector block features a dual-rated aluminum body, a high-dielectric plastisol outer coating, and a 3/0 to 6 AWG wire compatibility range.
Rated for 600V and pre-filled with oxide-inhibitor gel, this compact 3.35-inch terminal block provides a safe, tape-free splicing solution for copper and aluminum conductors inside breaker sub-panels and junction boxes.
Key Features & Benefits
- Dual-Rated Conductor Splicing
This dual-rated insulated connector block seamlessly supports aluminum-to-copper, aluminum-to-aluminum, and copper-to-copper wiring configurations. The versatile bi-metallic terminal design prevents galvanic corrosion when joining dissimilar conductors in high-voltage panels.
- Pre-Filled Antioxidant Gel
Internal wire ports are pre-filled with oxide-inhibitor gel to prevent contact oxidation and ensure reliable electrical conductivity. This moisture-blocking lubricating compound actively seals the wire entry points to boost long-term electrical performance.
- High-Dielectric 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 shield resists chemical exposure, impact, and extreme temperatures from -49°F to 194°F.
- Extended Gauge Versatility
The four-port terminal block accommodates a wide wire gauge spectrum ranging from 3/0 down to 6 AWG. Secure 7/32-inch hex head bolts provide high clamping force on each conductor to guarantee stable 600V connections.
- Sub-Panel Space-Saving Compactness
The compact 3.35″ x 1.77″ enclosure footprint fits easily inside crowded electrical junction boxes, breaker sub-panels, and control cabinets. This space-saving electrical splice block replaces bulky traditional split-bolts to streamline layout organization.
