Applications
This box is used to connect a power supply cable to 2 self-regulating cables. It can be mounted flat on a surface, or on a pipe. The surface temperature of the tube must not allow the box to exceed its maximum permitted surface temperature.
The terminal blocks are easily accessible and the connection is very simple, in particular for flat self-regulating cables with metallic protective braid.

Main technical features
Material: Black PPS, 91mm × 86mm × 44mm excluding cable glands. Superior UV resistance.
Waterproofing: IP67, IP69K (hot high pressure washing).
Shock resistance: The highest, IK10 (excluding cable glands).
Fixings:
- Wall mounting: 2 wall mounting lugs allow the mounting on a flat surface. Holes distance 112 × 45mm.
- Pipe mounting with 10mm offset: Two removable stainless steel legs allow mounting on a tube using a nylon tie or metal clamp. The distance from the tube limits the heating of the box.
- Pipe mounting with 50mm offset: Two removable stainless steel legs allow the installation of a thermal insulation and its protection before screwing on the box and making electric connections (Available as accessories, see catalogue page on 6YTQW parts).
Terminal blocks:
- These terminals are of cage type with tightening by screw. Their design protects them against loosening by vibration.
They can accommodate conductors up to 6mm², or up to 40A maximum.
They are suitable for this type of cable whose conductors are often of a flexible type, with many small diameter strands which can be damaged by clamping screw terminals with or without a protective blade.
- The mechanical retention of the cable is ensured by an independent jumper for round cable or for flat cables.
This patented metal jumper also ensures the grounding of the metal braid of the heating cables.
- Limit size of round power supply cables: 8; 12, 14 or 16.3mm depending on the fittings and clamping jumpers installed.
- Limit sizes of oblong cables:
- from 8 × 5 to 9.5 × 6mm
- from 9.5 × 2.5 to 11 × 3.5mm
- from 11 × 4 to 13 × 6mm
- from 12.5 × 8 to 14.2 × 9.2mm
Interconnection: The neutral terminals (N) of the different outputs and inputs are interconnected by an internal shunt, as are the phase (L) and earth terminals.
Cable exit: Via M25 cable glands, with NBR 70 Shore gaskets (Silicone possible on request).
Inviolability: The case can receive one or two seals (delivered with 5 red seals), as well as a lid chain Identification: By anodized aluminum label, riveted
Easy assembly: Assembly is done with the lid open.
Mounting on a wall or on a tube can be done with the cover open or closed.
