VOLTUS VSP-HKVAZD-6-1 Heating Circuit Distributor Junction Box | Single terminal

Connection box for actuators in the heating circuit distributor

No more loose terminal blocks and cable chaos in the heating circuit distributor: This junction box brings order to the wiring of your underfloor heating. It is mounted directly in the heating circuit distributor and serves as a central distribution point from which the individual actuators are connected cleanly, clearly and in accordance with standards.

The basis is the proven Spelsberg Abox 025/2 AB-L, a robust junction box with a high protection rating, compact dimensions and external mounting tabs. Inside is a mounting rail with high-quality Phoenix Contact Push-in terminals from the PTVFIX series. The conductors are plugged in without tools, the orange push buttons make releasing easier. Colour-coded terminals and labelling ensure that each connection is immediately clearly identifiable.

Six complete terminal groups each with one terminal for live conductor (grey), neutral conductor (blue) and protective conductor (green-yellow), each with two connection points and labelled L1, N and PE. Ideal if each actuator or each heating circuit is to be carried out as its own, separate electrical circuit, for example to extend the actuator cables or to cleanly separate individual zones.

Your advantages at a glance:

• All parts in one article number. You just have to assemble them.
• Tool-free Phoenix Contact Push-in connection technology for fast and vibration-proof wiring.
• Clear colour coding and labelling for clarity during installation, service and troubleshooting.
