The Wico miniature circuit breaker (MCB) is designed to protect low-voltage electrical networks from overload and short-circuit conditions, and to provide infrequent manual switching. The D tripping curve makes it suitable for loads with high inrush currents, such as motors and transformers.

It mounts on a standard 35mm DIN rail for installation in consumer units and distribution boards. The unit is EU-origin and meets EN 60898-1 and CE standards, with an IP20 protection rating for indoor panel enclosures.

Key Features

• 1-pole (1P) single-phase protection
• Rated current 32A with D tripping curve for high-inrush loads
• Short-circuit breaking capacity 4.5kA
• DIN 35mm rail mounting for standard distribution board installation
• Rated voltage 230/400V

Product Benefits

• D curve tripping characteristic provides the delayed response needed for motor and transformer start-up inrush without nuisance tripping
• 4.5kA breaking capacity handles short-circuit fault currents typical in domestic and light-commercial low-voltage networks
• Single-pole format isolates one phase, enabling selective protection in multi-circuit distribution boards
• DIN 35mm rail mount simplifies installation alongside other modular devices in the same enclosure
• EN 60898-1 and CE compliance confirms the device meets EU safety requirements
