HT-24 Surface-Mounted Hermetic Distribution Board, 24 Modules, IP65, Grey

Electrical installations in dusty, damp, or outdoor environments demand enclosures that shield components from moisture and mechanical impact. The HT-24 hermetic distribution board answers this need with a robust IP65-rated housing, ensuring reliable protection for circuit breakers, residual current devices, and other modular equipment in challenging conditions.

Who is it for

This distribution board is intended for electricians, panel builders, and facility managers who require a dependable surface-mounted enclosure for residential, commercial, or light industrial applications. It is particularly suited to locations where dust, splashing water, or physical contact pose a risk to electrical components.

Main features

• 24-module capacity arranged in two rows of 12, accommodating a wide range of DIN rail devices.
• IP65 protection against dust and water jets, making it suitable for outdoor or wash-down areas.
• Transparent polycarbonate door allows visual inspection of installed equipment without opening the enclosure.
• Impact resistance rated IK07, providing durability against mechanical shocks.
• Constructed from UV-resistant ABS with a grey RAL 7035 finish for long-term colour stability.
• Includes two 12-module DIN rails and N+PE terminal blocks for quick installation.
• Pre-marked knockouts on top and bottom simplify cable entry and maintain enclosure integrity.
• Complies with PN-EN 62208 and PN-EN 61439-3 standards for empty enclosures and distribution boards.

Tips

When selecting cable glands or conduit fittings, ensure they maintain the IP65 rating of the enclosure. Use appropriate sealing washers and tighten to the manufacturer's torque specifications. For outdoor installations, consider additional protection from direct sunlight to prolong the life of the polycarbonate door, although the ABS body is UV-resistant.
