DX3 Type AC compact RCBO (2-module double pole and 4-module four pole) to NFC 61-410 / EN 61009-1; 2-pole 6-32 A, 4-pole 10-32 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

• Compact 2-module (DP) and 4-module (FP) construction
• Rated sensitivity 30 or 300 mA
• Blue indicator in front face window on earth-leakage trip
• Test button for monthly testing

Applications

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