Series
HF Series — Cam Switches (25 A / 32 A / 40 A / 63 A)
Motor-circuit rotary cam switches · 25 A to 63 A frames · AC1 17–35 kW · IP40
Tecnomatic HF cam switches for motor starting, change-over, and main-switch service in heavier control panels. AC1 rated 17 kW (HF 25) / 20 kW (HF 32) up through HF 63. Larger handles and contact sets than HD, identical AG/NI material and polycarbonate insulation. Configurations cover 1–4 pole switches and change-overs, 3-pole reversing, pole commutator, and 3-pole switches with embedded T341 mechanical interlock (T-mount variants) for reversing-starter pairs.
