A2K & A6K Series / Class RK1 / Fast Acting
The A2K & A6K Series / Class RK1 / Fast Acting is part of the Mersen (formerly Ferraz Shawmut) general purpose fuses line, distributed by Gross Automation.
These fast-acting fuses deliver a high degree of current limitation - Current-limiting A6K fuses provide excellent protection where high available short circuit currents exist. These fast-acting fuses are particularly good for branch/feeder circuits and back-up protection.
