The fusible switches in it’s two series, are manufactured with high safety self-extinguishing materials, providing an excellent level of electrical insulation, low smoke emission and high resistance to electromechanical stress.

They combine in a compact unit, the function of a switch – disconnector with protection against overloads and short – circuits given by the fuses, these once installed remain fixed in the switch, ensuring a long electrical and mechanical life and safe opperations for the user.

They comply with environmental requirements and undergo strict quality controls for a reliable product that meets the most demanding requirements.

The M21 series consist of a sandwich-type body containing self-cleaning blade type contacts, with pre-arc zones to ensure long term, fault-free energy transmission and coated with silver alloy for long term electromechanical life, externally has housings to insert fuses according to the apropriate format. The detent mechanism provides quick and independent switching due to the  accumulation of elastic potential energy, which is transmitted at  high speed to the contacts of arc extinction. 

The M11 Series is of modular construction, with the contacts being moved  by a cross shaft with tripping being positive opening.
