Frequently asked questions
Why choose a B-curve breaker like the 5SY6102-6 for certain applications?
A B-curve breaker is chosen for circuits with low inrush currents, such as those with purely resistive loads or sensitive electronic devices. The Siemens 5SY6102-6's B-curve ensures it trips quickly on overloads and short circuits without nuisance tripping from minor, brief surges.
