Non-Fusible: 30  • 40 • 63  • 80  • 125 • 160 Amp / Fusible: 30 Amp

ACI's  Fusible and non-Fusible Disconnect Switches are UL Listed under UL508 to disconnect the power source (single or three phase) from a control panel or any other application where the line power is required to be turned “Off”. Example: Load or motor disconnect switches, safety switches for air conditioners, pumps, compressors, main switches, distribution switches, lighting panels, etc. These switches are not for Service Entrance.
This patented, modern and compact switch design utilizes state of the art technology to minimize panel space and maximize switch capability. The unique patented Fusible Disconnect Switch incorporates an integral enclosed fuseholder within the body of the switch, eliminating the need for a separate fuseblock. The enclosed fuseholder design minimizes the risk to the operator in case of accidental contact with live parts. The fuseholder accepts Class CC rejection type fuses and is totally finger safe.

A wide range of operators are available, with a 22MM Mounting Style as the standard used with all “Base Mount” Disconnects. All operators are rated Type 4 (IP65). The lockable handle assembly meets the requirements of OSHA Standard 1910.147 (Lockout) for control of hazardous energy sources. The ACI Fusible and Non-Fusible Switches are UL listed and conform to IEC 408; CEI 17-11; CEE 24; VDE 0660T107; and BS 5419 and CE.

Add-on power poles are available (see accessories).
Up to two additional power poles may be added to these Disconnects, with the exception of the 30A fused unit, which will accept only one additional power pole.
