Product Description

The Schneider Electric Acti9 iC65N 2P B4A is a high-quality miniature circuit breaker from the Acti9 iC65N series, providing precise overload and short-circuit protection for low-power, sensitive loads in residential, commercial, and light industrial applications. The B-curve tripping characteristic (fast response at 3–5 times rated current) is ideal for circuits with low inrush currents such as lighting, control circuits, instrumentation, small electronics, and resistive loads. The 2-pole configuration protects both live and neutral conductors, while the compact DIN-rail mounting (2 modules) and VISI-TRIP indication make it perfect for distribution boards and control panels.

Standard Features

  • 4 A B-curve rating: Optimal for low-current, sensitive circuits — fast tripping on moderate overloads and short circuits.

  • 6 kA breaking capacity: Handles typical faults in domestic and light commercial installations (higher 10 kA per IEC 60947-2).

  • 2-pole design: Protects both live and neutral — common in single-phase circuits requiring full isolation.

  • VISI-TRIP & positive indication: Red flag shows tripping status — quick fault diagnosis.

  • Compact 2-module width: 36 mm wide — fits standard consumer units and modular panels.

  • Global certifications: IEC/EN 60898-1, IEC 60947-2, CE, CCC — widely accepted for distribution protection.
