RCD extension board with type F and type EV RCDs, 30 mA

The RCD extension board demonstrates the design and operating principle of specific RCDs and how to wire them sensibly. The RCD extension board can be used to convey the following training contents:

• RCDs in TN or TT systems
• Measurement and assessment of tripping values (time, leakage current)
• Differences between type F and type EV RCDs
• Investigation of selectivity of cascaded RCDs
• Measure of leakage current for AC or DC leakage currents

Technical data:

• Operating voltage: 400 V/50 Hz
• Type F RCD, I_Dn =30 mA
• Type EV RCD, I_Dn =30 mA/6 mA DC
• Inputs and outputs: 2-mm safety sockets
• Dimensions: 297 x 228 x 80 mm
• Weight: 1.8 kg
