The ABB SH202-D32 (catalogue code 2CDS212001R0321) is a 32A, 2-pole, D-curve Miniature Circuit Breaker (MCB) from the ABB System PRO M compact® series. This MCB is engineered to provide reliable overload and high inrush current protection for circuits with significant startup surges. The "D" tripping characteristic features a delayed magnetic response, making it the ideal choice for protecting inductive loads such as transformers, solenoids, welding equipment, and particularly single-phase and certain three-phase motors, where high starting currents (up to 10-14 times the rated current) are common. It prevents nuisance tripping during equipment startup while maintaining robust short-circuit protection.
