DX3 Type A four-pole RCBO (EN 61009-1 / IEC 61009-1), sensitive to residual AC and DC-component currents; 25, 32 and 40 A, 30/300 mA. RCBOs provide fault current detection, measurement and cut-off, protection against overloads and short-circuits, and isolation of an installation.

Key features

• Type A: sensitive to residual alternating currents and residual currents with a DC component
• Four-pole 4-module construction
• Rated sensitivity 30 or 300 mA
• Blue indicator in front face window on earth-leakage trip

Applications

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