Description

The Fusebox Triple Pole MCB Type B (Curve B) is a robust, high-performance miniature circuit breaker designed for three-phase electrical distribution systems. Providing safe, reliable overload and short-circuit protection, these MCBs are commonly used in commercial, industrial, and large domestic settings. The Type B trip curve offers protection against standard lighting and small appliance circuits with a low inrush current, ensuring a quick trip between 3–5× the rated current. Built to the latest IEC/EN 60898-1 standards, the Fusebox Triple Pole MCB is an ideal choice for distributing three-phase power efficiently and safely.

Features

  • Triple pole design for full three-phase protection
  • Type B trip characteristic — ideal for lighting and general-purpose circuits
  • Quick tripping at 3–5× rated current for overload and short-circuit protection
  • High breaking capacity up to 6 kA
  • DIN-rail mountable for rapid installation
  • Compact modular unit that fits standard Fusebox distribution boards
  • Conforms to IEC/EN 60898-1 safety standards for total peace of mind
