The WKC216D is a 16 A 2 Pole 10 kA Miniature Circuit Breaker (MCB) designed for protecting motor, pump, and automation circuits with high inrush current. Its D-curve tripping characteristic allows 10–20× rated current at start-up, ensuring reliable protection for transformers, coils, and inductive control gear without nuisance tripping.
This dual-pole MCB isolates both live conductors simultaneously, providing safe disconnection and compliance with BS EN 60898-1. Its 36 mm housing fits any standard 35 mm DIN rail — suitable for consumer units, industrial boards, and commercial distribution panels.
Installer Tip: Use a 16 A D-curve MCB on circuits supplying small industrial motors, pumps, or automated plant. If loads are primarily resistive or low-surge, consider the C-curve version instead.
