Mersen IEC-rated fused disconnect switches are extremely durable, manually operated, and versatile. They can accommodate DIN and NFC fuses up to 1250A. They employ double break contacts per pole that ensure complete isolation of the fuse when the switch is in the OFF position. They have a TEST function that enables testing of the control circuit auxiliaries without switching the main contacts. This function provides a simple alternative to a separately wired push button. A wide array of handles is available to meet padlocking requirements and the shafts are widely adjustable.
