The WKC232D is a 32 A 2 Pole 10 kA Miniature Circuit Breaker (MCB) built for protecting motor circuits, compressors, and feeder supplies with high start-up current. Its D-curve tripping profile tolerates 10–20× rated current at energisation, ensuring dependable operation for industrial and commercial inductive loads.
Featuring dual-pole isolation, both live conductors disconnect simultaneously for safe maintenance and compliance with BS EN 60898-1. Compact 36 mm housing fits standard 35 mm DIN rails used across industrial boards, distribution panels, and consumer units.
Installer Tip: The 32 A D-curve breaker is ideal for motor feeds, compressor lines, and control circuits where B or C curves may trip unnecessarily. For lower surge applications, opt for the C-curve version.
