Key Features and Benefits
- Largest enclosure in the range at 140x190x100mm — the extra 190mm length and 100mm depth gives generous internal volume for routing thick cable bundles.
- 20x 4 Sqmm terminals on 35mm DIN rail — highest terminal count in this series, all fitted and aligned factory-straight for immediate wiring.
- 6x PG13.5 glands across the enclosure body — three times the cable entry points, allows separate entry for input, output, and earth cables cleanly.
- Silicon Sponge O-ring runs full perimeter of the large lid — longer O-ring path means more consistent compression seal across the wider enclosure.
- Nylon 6 GF 30% screws at 10 fixing points — more fixing screws than smaller variants to maintain even lid compression across the larger surface area.
- 2x end stoppers and 20x end plates — full individual locking of every terminal block prevents any shift in a high-density wiring environment.
Technical Specifications
- Enclosure body made from virgin ABS plastic in RAL 7035 grey with IP67 dust and water protection rating.
- IK07 impact resistance — handles mechanical knocks from tools and accidental impacts without cracking.
- Operates reliably from -20°C to +70°C, suitable for outdoor summer heat and cold industrial environments.
- Lid sealed with Silicon Sponge O-ring running full perimeter, compressed by Nylon 6 GF 30% screws for consistent weatherproof closure.
- 20x 4 Sqmm Elmex/Vittal screw-clamp terminal blocks pre-mounted on 35mm DIN rail, accepting wire sizes 0.5 Sqmm to 4 Sqmm, rated up to 25A per circuit.
- 6x pre-fitted PVC PG13.5 cable glands — suits cable outer diameters from 7mm to 13mm.
- 2x end stoppers and 20x end plates secure terminal blocks firmly on DIN rail after installation.
- CE and RoHS compliant, UL 94-HB fire resistance rated, UV protected for long-term outdoor use.
