Circuit Protection

IC65 1P MCB C-Curve 6kA Miniature Circuit Breaker

Walax IC65 single-pole C-curve MCB — the air switch configuration popular in residential and commercial sub-circuits where moderate inrush is expected. Compact 18mm module width saves DIN-rail space in densely packed boards.

Compact 18mm Module

Single-pole MCB fits in an 18mm module width — maximum density for residential distribution boards with many sub-circuits.

C-Curve Tripping

Trips between 5× and 10× rated current — ideal for circuits with moderate inrush (small motors, fluorescent lamps, transformers).

Tropicalised Build

Anti-humidity treatment and corrosion-resistant contacts as standard for harsh climates in export markets.

FAQ

Frequently Asked Questions

What does C-curve mean?

C-curve means the breaker trips instantaneously when the current exceeds 5× to 10× the rated current. This makes it suitable for circuits with moderate inrush currents such as motors and fluorescent lighting.

Is this a direct replacement for IC65N?

Yes — same footprint, same terminal layout, same module width. Direct drop-in replacement for Schneider IC65N and equivalent brands.

What ratings are stocked?

Common ratings (C6, C10, C16, C20, C25, C32, C40, C50, C63) are stocked for fast shipment. Custom ratings available on request.

Do you provide test certificates?

Yes – IEC 60898-1 type-test reports and CE documentation accompany every shipment. Third-party certificates (TUV, KEMA) on request.
