Product Description

The Schneider Electric A9N18102 is a specialized 1-pole miniature circuit breaker designed for Direct Current (DC) applications. Part of the Acti9 iC65N-DC series, it features a 2A rated current and a C-curve tripping profile. This MCB is engineered to handle the specific arc-extinguishing requirements of DC circuits, making it ideal for renewable energy systems, telecommunications, and industrial DC control loops. With its high breaking capacity and robust build, the A9N18102 provides reliable protection against overloads and short circuits in sensitive electronic and power systems operating on DC voltage.

Standard Features

  • DC Fault Protection: Specifically tuned magnetic trip levels for Direct Current fault characteristics

  • Polarity Sensitive: Optimized internal design for unidirectional DC current flow (follow marking for wiring)

  • Safe Isolation: Provides guaranteed isolation of DC circuits for safe maintenance activities

  • Multi-Standard Compliance: Designed to meet industrial standards for DC infrastructure

  • Compact Modular Design: Standard 18mm width per pole for easy integration in Acti9 distribution boards

  • Durability: High mechanical and electrical life even under DC inductive load switching
