WebD-type MCBs are the least sensitive type, only activating when current surges to between ten and twenty times the recommended maximum. D-rated MCBs are built for heavy … WebType D MCBs are the least sensitive MCBs, designed to trip instantly at currents 10 to 20 times the rated current. As a result, they’re ideal for inductive loads and other applications with large power surges. Uninterruptible power supply (UPSs), heavy motors, transformers, X-ray machines, and welding equipment all use Type D MCBs.
