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 for On-Board applications under 85VDC, 750VDC, 1,500VDC, 3,000VDC and 25kVAC. Mersen has a switch solution that will meet your unique needs. Our standard On-Board FA disconnector range is rigorously engineered to meet your technical specifications in different configurations (Disconnector, Change-over, earthing). Operation : They can be operated manually or with an adapted motor (see list) up to 25.000 cycles. Phase to Phase distance, Signaling, Terminal Box or Locking system can be studied and customized.
