DX3 Type AC RCBO to IS 12640 (Part 2) / IEC 61009-1 with overload and short-circuit protection; 2-pole 6-63 A and 4-pole 16-63 A, 30/100/300 mA. RCBOs provide fault current detection, measurement and cut-off, protection against overloads and short-circuits, and isolation of an installation.

Key features

• Type AC: sensitive to residual alternating currents
• Rated sensitivity 30, 100 or 300 mA
• Breaking capacity 10000 A (Icn)
• Test button for monthly testing

Applications

• Combined earth-leakage, overload and short-circuit protection of final circuits
