For more than 100 years, Mersen has been providing the market with safe, reliable and longer life time off-load disconnectors. These devices offer high performances and robustness for heavy duty requirements with very limited maintenance. Mersen offers one of the largest product ranges on the market and is the global leader. Mersen has a switch solution that will meet your unique needs. Our standard MF High Power Switches are rigorously engineered to meet your technical specifications. Operation : They can be operated manually or with an adapted motor (see list) up to 60.000 cycles. Phase to Phase distance, Signaling, Terminal Box or Locking system can be studied and customized. Maximum frequency up to 3.000Hz (above please consult) Indoor in a currentless state Ambient air should not exceed +40°C (otherwise please consult) Altitude should not exceed 1000 m Relative humidity should not exceed 95% List 1 following IEC 62271-1

Quick Overview

No Load operation
Indoor Type - Non Magnetic and tropicalized equipment which can be installed in vertical or horizontal position
Change-over (2 or 3 positions) or disconnector configuration with 1 to 10 poles double sided and 12 poles single sided technology. Warning , when reversing, the isolation between terminals 1 and 2 is not ensured.
Mechanical endurance : 60.000 cycles minimum warrantied for a device maintained according to the maintenance recommendations.
Electrical contact by connecting plates and movable contacts silvered copper entirely non-magnetic
Pressure of each rivet ensured by an individual spring in stainless steel.
Temperature rise at nominal current is less than 65°K (with 40°C max. ambient temperature)
Visible break by direct seeing of the mobile silver-plated copper contacts.
Large isolation air and creepage path.
Easy connections to Copper busbar by bolting and self-supporting (Busbar must be sized to withstand the disconnector additionnal weight).
Self-cleaning blade contacts.
True opening and visible distance.
Ponctual temperature withstand without equipment damages 140°C.
Full customisation with :
- Manual (handle or gear box), motor, pneumatic drives operation
- Quantity of Auxilary switches, safety blocking magnet, locking devices
- Dimensions of the disconnector and Fittings/connexions to the busbar.
Fixing flange in duralinox.
