Electrical Safety Technology Series 2300

System Overview

The teaching system is used for measurements in the field of electrical protection measures and installation technology.

It consists of seven teaching boards, an experiment manual and any commercially available test instrument. Measurements are performed directly at 230 V / 400 V; tests according to country-specific standards are possible.

Teaching Boards and Modules

• Type 2350 - Transformer station supplying all teaching boards of the system; Cekon CEE connection; 4-pole MCB B6; output 230 V (phase / N) and 400 V (phase / phase); housing 266 x 297 x 100 mm; weight approx. 2.5 kg.
• Type 2351 - House and equipotential bonding; each phase can be switched; different networks shown; local equipotential bonding switchable; various earth resistances switchable; 12 faults switchable; earth probe for measurement with a standard meter.
• Type 2352 - Fuse box; replica of a domestic fuse box with 2 x combined protective switches, 4-pole MCB, replaceable 4-pole RCD and test potentiometer.
• Type 2353 - Apartment; replica of a four-room apartment; 15 faults switchable; cooker connection box with 4 mm safety sockets; sockets, switches and lamps integrated.
• Type 2354 - Isolation transformer; 3-phase 400 V / 50 ... 60 Hz; delta input, star output; screen winding to PE; galvanically isolated.
• Type 2355 - IT system; insulation monitoring with industrial insulation monitor; RCD and MCBs; socket, switch and lamp; potentiometer for RCD tests.
• Type 2356 - Consumer TT system; load board in TN / TT system with simulation of a 3-phase consumer, various earth resistances and an earth probe.
• Type 2352.1 - RCD protection switch 300 mA type A for the fuse box, exchangeable and with safety sockets brought out.
• Type 2352.2 - RCD protection switch 30 mA type B for the fuse box, all-current sensitive and exchangeable.
• Type 2352.3 - RCD protection switch 300 mA type A, selective; separate A-format board for upstream connection before the fuse box.

Recommended Accessories

For the experiments of the manual we recommend the conductor set Type 2350.1; it includes safety leads and safety connectors in different lengths and colours.

Any commercially available test instrument for measuring electrical protective measures can be used; the preferred device used for the manual was the Profitest SII+ / 0100.

• Type V 0119 - Experiment manual Electrical Safety Technology and Networks.
• Type 2350.1 - Conductor set: 6 x 1.5 m safety leads, 12 x 75 cm safety leads, 2 x 25 cm safety leads, 30 x safety connectors.
