Wico MCB 1P+N C20 A 4.5 kA DIN Rail – C-Curve, Switched Neutral & 230/400 V AC

The Wico miniature circuit breaker (1P+N/C20A/4.5kA) combines a single protective pole and a switched neutral in one device, rated at 20A with a 4.5kA short-circuit breaking capacity. It protects low voltage electrical networks from overload and short-circuit faults, and handles infrequent switching duties.

Compliant with EN 60898-1 and CE marked, it clips onto a standard 35mm DIN rail and carries an IP20 indoor protection rating. The C tripping curve suits general purpose loads including resistive and moderately inductive circuits.

Key Features

• 1P+N configuration — switches both the live pole and the neutral simultaneously
• C tripping curve for general purpose circuit protection
• 20A rated current with 4.5kA short-circuit breaking capacity
• DIN 35mm rail mounting
• IP20 protection rating for indoor installations
• EU origin

Product Benefits
