3-Pole Mains Terminal Block for Norsup SP28T / SP35T Heat Pump (UTD-32/3P L-N-PE) - 7036957

Bosta – 3-Pole Mains Terminal Block for Norsup SP28T / SP35T Heat Pump (UTD-32/3P L-N-PE)

This is the genuine replacement 3-pole mains terminal block (type UTD-32/3P, L–N–PE) for the Norsup Silent-Pro SP28T and SP35T pool heat pumps. It provides the three essential electrical connection points — Live, Neutral, and Protective Earth — inside the heat pump’s junction box, forming the secure interface between the incoming mains supply and the unit’s internal wiring.

Screw-clamp in design, the UTD-32/3P is a DIN-rail-mounted modular terminal block built for reliable, vibration-resistant connections in demanding electrical environments. Replacing a damaged or worn terminal block with a genuine Norsup-specified part ensures the heat pump’s mains connection remains safe and up to the original electrical ratings.

Compatibilidade

This terminal block is specified for the Norsup SP28T and SP35T pool heat pumps only. The SP28T and SP35T are large-capacity Silent-Pro series units designed for pools of 50–130 m³. Always verify your heat pump model before ordering, as terminal configurations differ across the SP range.

Porque o Genuíno Importa

Mains terminal blocks carry the full supply current to the heat pump. Using a genuine, correctly rated replacement — rather than an aftermarket substitute — ensures the connection meets the original design tolerances, maintains compliance with the unit’s electrical certification, and protects both the appliance and the installation.

Instalação

Installation must be carried out by a qualified electrician. The heat pump must be fully isolated from the mains supply before any work begins. The terminal block mounts on a DIN rail inside the junction box; the three supply conductors (L, N, PE) are secured via screw clamps. Consult the Norsup SP28T/SP35T service manual for wiring diagrams and torque specifications.
