397-4 Bench With 4 Workstations For Practical Electrical Testing Teaching Equipment Electrical Workbench
This bench has been designed to enable students to develop a complete program of practical assembling, wiring and testing exercises of lighting installations, signalling systems, industrial electric and electro-pneumatic installations. TECHNICAL SPECIFICATIONS: This bench is made of welded sheet steel and section,chemically treated and painted with several coats of epoxyvarnish; the working top of chipboard coated with bonded laminate, includes two drawers on each side (a drawer for eachworkstation). Panels are fixed on the vertical frame by hinges for an easyassembling and removal; thus the realized circuit must not bedisassembled. Each front of the bench (two workstations) is provided with thefollowing power supply: • 1 three-phase (230 or 400 V) and single-phase (230 V – 16 A) line, protected by high-sensitivity magneto-thermal differential circuit breaker, safety terminals, emergency button with mechanical holding, minimum voltage release device • Four-pole switch with key control that can be extracted only in zero position to enable three-phase line • 1 single-phase line of 12-24 Vac – 4 A (safety extra-low voltage) protected against overloads and short-circuits by fuses and by magneto-thermal circuit breaker • 1 circuit tester with light-acousticsignalling (powered with extra-low voltage) Dimensions: 2.000 x 1.000 x 850 + 850 mm Net weight: 98 kg Supply with THEORETICAL – EXPERIMENTAL HANDBOOK
