The WKC206D is a 6 A 2 Pole 10 kA Miniature Circuit Breaker (MCB) engineered for circuits with high inductive or transformer inrush current. Its D-curve tripping profile allows 10–20× rated current on energisation, providing reliable protection for motors, coils, transformers, and control gear without nuisance tripping.
With dual-pole isolation, both live conductors disconnect simultaneously for safe maintenance and full compliance with BS EN 60898-1. Compact 36 mm body fits all 35 mm DIN-rail enclosures including consumer units, industrial enclosures, and three-phase panels.
Installer Tip: Use a D-curve when protecting circuits with high start-up surge – for example, motors, transformers or inductive control gear. For lighting or low-inrush loads, see the C-curve model.
Key Features

When is a D-curve MCB required?
D-curve breakers are used for motors, transformers or other high inrush equipment that might trip B or C curves on startup.
Does it disconnect both live conductors?
Yes – 2-pole isolation cuts both lines simultaneously for safe maintenance.
Can it be used in industrial control panels?
Yes – ideal for panels with coils, contactors, or transformers drawing brief surge currents.
Is it 18th Edition compliant?
Yes – tested to BS EN 60898-1 and fully compliant with current wiring standards.
