Commercial SP MCBs C Curve

Commercial SP MCBs with a C Curve are designed to protect single-phase circuits where moderate inrush currents are common, such as those powering motors, transformers, or fluorescent lighting in commercial settings. These MCBs trip between 5 to 10 times their rated current, providing a balance between sensitivity and stability. Compact and easy to install, they offer reliable overload and short-circuit protection while optimising space in distribution boards. Available in a range of current ratings.
