397-2 Bench With 2 Workstations For Practical Electrical Testing Educational 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 bondedlaminate, includes two drawers on each side (a drawer for eachworkstation). Panels are fixed on the vertical frame by hingesfor an easy assembling and removal; thus the realized circuit must not be disassembled. Each front of the bench (one workstation) is provided with thefollowing power supply: • protection by high-sensitivity magneto-thermal differentialcircuit 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-acoustic signalling (powered with extra-low voltage) Dimensions: 1.050 x 900 x 850 + 850 mm Net weight: 74 kg Supply with THEORETICAL – EXPERIMENTAL HANDBOOK
