Merlin Gerin

Find a great selection of obsolete and discontinued Merlin Gerin MCB’s online with Zetmet Ltd. The once highly popular Multi 9 range of circuit protection was discontinued upon being replaced by a Schneider equivalent. More recently they were rebranded to become the Acti 9 range.

With numerous next day delivery options and even a same day “click and collect” option (both Mon-Fri) be sure to get the product you need when you need it!
