Compact switch fuses

The modular design of these disconnectors with fuses allows them to be adapted to the number of poles specified and it has been ergonomically designed and manufactured to meet the needs of the industrial sector giving the M3 a much smaller footprint.

Developed with panel construction in mind, Telergon designed the M3 series to be the most compact switch fuse on the market, enabling panel designers to save space within panels, which in turn reduces enclosure size, installation time and therefore cost.

The M3 Series is comprised of three sizes and can be specified to accept different types of fuses to suit all applications, DIN, BS, NFC & UL. Currently available from 32 Amp up to 250A, with larger sizes under development, the M3 Series is available in 2P, 3P & 3P+N with the range benefiting from versions with a detachable neutral.

Available in some models within the M3 series, a built in TEST position enables the user to test the control circuit auxiliaries fitted to the switch without switching the main contacts of the switch fuse. This is often an important part of maintenance procedures and testing, as described within WIMES 3.01 & 3.04 (Water Industry Mechanical and Electrical Specification) facilitating maintenance and enhancing the safety of the equipment.

With safety and simplicity at the fore front of the design the M3 range is supplied with interlocked fuse protection covers which cannot be opened in the ‘ON’ position and their transparency allows easy visibility of fuses.  It also includes an optimised contact system for improved overload and short circuit protection.
The innovative design of the M3 allows it to be mounted horizontal (standard), vertical and at a 45˚ angle if so desired.

Switchtec has had a long-standing partnership with Telergon, the switch specialist, who have more than 65 years’ experience in switchgear design, manufacturing and R&D with a presence in more than 100 countries.
