The slimline Martindale LOK7 is less than half the width of a standard MCB lock and around 30% shorter. The reduced size makes it ideal for use where clearance around the breaker is limited. The slimline design is particularly well-suited to breakers where the position of the test button may prevent the use of conventional lock outs. * Martindale type MARLOK7 https://elecena.pl/product/27214411/martindale-lok7-mcb-small-black-isolation-lock 2024-11-10 https://elecena.pl/product/27214411/martindale-lok7-mcb-small-black-isolation-lock 2025-05-20 https://elecena.pl/product/27214411/martindale-lok7-mcb-small-black-isolation-lock 2025-09-16 https://elecena.pl/product/27214411/martindale-lok7-mcb-small-black-isolation-lock 2026-03-15
