    Special Price $269.98 Regular Price $400.00

    Mersen Gould Shawmut - AMP-TRAP - A4BQ1200 - FUSE TIME DELAY 1200A 600VAC

    Amp-Trap 2000® A4BQ fuses are 20% more current-limiting than any other Class L fuse on the market. When correctly coordinated, they bring a superior level of protection to service entrance equipment. Downstream circuit components have maximum protection against short circuit let-thru current. A4BQ’s built-in, 4-second time-delay characteristic (at 500% of rated current) accommodates harmless inrush currents without nuisance opening.

    Fuse Type:Time-Delay, Class L, 200kA AC, ,

    Current: 1200A

    Voltage: 100kA DC, 600VAC/500VDC

    Cooper/Bussmann - KTU800 - Fuses.

    Fast-acting, nonindicating UL Class L fuses open within seconds of being exposed to overloads and short circuits. Also called fast-blow Class L fuses, they are highly sensitive to changes in current flow and don't tolerate temporary overload currents or power surges. They have no indicator for identifying a blown fuse, so they're sometimes used with an indicating fuse block or cover.

    Semiconductor Fuses.

    800Amp 600V, fast acting, current limiting.
