The Wico miniature circuit breaker (3P/D3X25A/6kA) is a 3-pole device rated at 25A per phase for use in 230/400V low voltage installations. It trips on both overload and short-circuit conditions, and its D tripping curve suits loads with high inrush currents.

It mounts on a standard 35mm DIN rail inside any indoor distribution board and is certified to EN 60898-1. The IP20 enclosure rating keeps it protected in normal indoor panel environments.

Key Features

• 3-pole (3P) configuration for 3-phase circuit protection
• Rated current 3×25A per phase
• Short-circuit breaking capacity of 6kA
• D tripping curve for loads with high inrush currents
• DIN 35mm rail mounting for standard distribution boards
• Indoor IP20 rating

Product Benefits

• Simultaneous 3-pole disconnection ensures all live conductors are isolated on a fault
• 6kA breaking capacity handles the fault currents typical of low voltage commercial and residential networks
• D curve prevents nuisance tripping on motor or transformer inrush at start-up
• Tool-free DIN rail clip-in installation speeds panel assembly
• EN 60898-1 and CE certification confirms compliance with European safety standards
