The 3-pole unit is designed for distribution applications and provides integrated earth-leakage protection with selectable sensitivity from 30 mA up to 5 A, covering both class A and class AC fault types.
The integrated earth-leakage protection with selectable sensitivity (30 mA, 100 mA, 300 mA, 500 mA, 1 A, 3 A, 5 A for class AC; 30 mA to 1 A for class A) allows you to set the trip threshold to match the installation's leakage current profile. A 30 mA setting protects personnel against direct contact; higher settings (300 mA and above) are used for fire protection or equipment protection where some leakage is expected.
The C11B34V025L mounts on a backplate (not DIN rail) and occupies 9 module pitches (9 x 18 mm = 162 mm) of width. The 108 mm width, 144 mm height, and 80 mm depth fit into standard distribution enclosures. Front-facing connections for both line and load simplify wiring. The Everlink terminals accept 2.5 to 95 mm² rigid or stranded aluminium/copper (fine stranded copper up to 70 mm²). The IK07 impact rating (2 J) means it withstands accidental knocks during installation.
