M3 Series: The Most Compact Range of Switch Fuses

Since our foundation in 1953, Telergon has remained faithful to the same philosophy: to respond and anticipate the needs of our customers by developing the most innovative switchgear solutions.

This focus has guided us in launching this series of switch-disconnectors with fuses, with a modular and compact design. Created to meet the needs of industrial applications and power electronics, its quality and high performance reinforce our competitiveness thanks to a complete and versatile offer, and revalidate Telergon’s commitment to quality and specialisation.

Modular design with new features

The M3 series, designed under a modular concept, is composed of 3 sizes adaptable to different kind of fuses (DIN, BS, NFC, UL). Able to reach up to 250A, they are available in 2P, 3P, 3P+N versions. One of the outstanding new features is the detachable fixed neutral option, which facilitates installation and maintenance.

Another new characteristic is that it includes the TEST position on the handle, which allows to test the control circuit auxiliaries without switching the main contacts, thus facilitating maintenance and guaranteeing the safety of the equipment.

Outstanding features

• The molded case is adapted to the number of poles
• Reduced footprint, the most compact range
• New direct handle: simpler and more ergonomic, with push-to-detach system
• Connection by cage or terminal, depending on the size
• Option of horizontal, vertical and 45° mounting orientation
• Front or side operation
• Easy to install and maintain

More safety

The M3 series puts safety first, and therefore includes transparent fuse protection covers that allow visibility of the fuses, which cannot be opened while the switch is in ON position. It also includes an optimised push-button contact system and overload and short-circuit protection.

Versatile range of switch fuses

Thanks to our specialisation in low voltage switchgear solutions, we offer complete solutions compatible with a wide range of accessories, such as auxiliary contacts, early or simultaneous, terminal shrouds, phase barriers… And also, the possibility of using front or side operation, with direct or external handle.
