Box with four-pole ON-OFF switch, 4-pole 25A for inductive loads (electric motors) and general control. 90º rotary knob, with two positions 0-1. Front plate size 66x66mm in yellow with red knob and padlock possibility. Box made of thermoplastic material. Degree of protection IP65 / Nema 4X in addition to protecting the equipment against dust, water, rain and snow, offers additional resistance to corrosion, making it ideal for environments with chemicals, salt spray or extreme weather conditions.
The switch-disconnectors of the LO series offer excellent quality, manufactured in Germany according to the strictest European and international standards (IEC/EN 60947, VDE 0660, UL, CSA), enabling them to meet all safety requirements. They are extremely robust and have been specially designed for use as main and emergency stop switches in machine tools and switch cabinets. When actuated, the main contacts are positively activated when switching on and off.
These compact switches are characterized by large separation distances, which ensure a high degree of safety. They have large creepage distances and clearance between the connections. The main switch with emergency stop function (red handle and yellow faceplate) has a lockable handle and safety terminals. It incorporates a safety system whereby it is only possible to remove the cover with the switch in position "O".
Surface mounting, dimensions 100x161x80.5 mm. Box prepared (pre-punched) for 8 cable glands (4xM25, 4xM20).
This switch is suitable for three-phase motors up to 4kw connected to 230Vac or 7,5kw connected to 400Vac.
