ASCO 918 Lighting Contactors for Branch Circuits

Durable Performances for Demanding Lighting Applications

The ASCO 918 provides reliable and convenient lighting control in numerous applications, including enhanced performance for high inrush current loads such as High Intensity Discharge (HID) and metal halide lighting. The ASCO 918 mounts in the same footprint as the ASCO 917.

Branch Circuit Control 2 to 12 Poles Reliability, Easy Installation

  • The ASCO 918 Remote Control (RC) Lighting Contactor has been designed for quick and simple installation. Available open or enclosed, the ASCO 918 is rated at 30 amperes to 600 volts AC*.
  • Key and slot mounting holes permit fast mounting with only three screws required to mount it into its enclosure. Fast termination is accomplished with all connections made from the front.
  • To reduce installation time, terminal plates rise with the screws and wire is simply inserted and tightened. Wire sizes in the No. 18 to No. 10 AWG range can be accommodated by the line, load and control terminals.
  • *Current rating for tungsten lighting applications is 20 amperes to 250 volts AC.

Durable Performances for Demanding Lighting Applications

The ASCO 918 provides reliable and convenient lighting control in numerous applications, including enhanced performance for high inrush current loads such as High Intensity Discharge (HID) and metal halide lighting. The ASCO 918 is listed under UL 508 with no de-rating when used open style, or enclosed. Electrical inspections will go more smoothly because the UL label and full rating information are clearly marked on the product’s nameplate.
