Pass Seymour 623 Fluorescent Lamp Holder 600VAC 660W

Product Description

The PASS SEYMOUR 623 is a single-pin, high output fluorescent lamp holder with a spring-loaded plunger, designed for snap-in mounting in fluorescent lighting fixtures. Rated at 600 VAC and 660 watts, it handles the demands of high output fluorescent lamp applications. The plunger mechanism provides secure lamp retention while allowing straightforward lamp replacement. At 1.88 inches in overall height, the white housing fits standard snap-in mounting cutouts found in commercial and industrial fluorescent fixtures. Installation is typically performed by licensed electricians or qualified lighting maintenance technicians.

The 623 is suited for high output fluorescent lighting installations in commercial, industrial, and institutional settings. Snap-in mounting makes it a practical replacement component in troffer-style and strip fluorescent fixtures where the original lamp holder has worn out or failed. The plunger-style design is commonly found in single-pin T12 HO lamp applications. This holder ships individually and is intended for use where a replacement of a single lamp holder is required rather than a full fixture swap.

Installation Notes

Installation should be performed by a licensed electrician or qualified maintenance technician in accordance with the NEC. Disconnect and lock out power to the fixture circuit before removing the existing lamp holder or installing the replacement. Snap-in lamp holders seat into the fixture channel under hand pressure; confirm the holder is fully seated before restoring power. Inspect lamp pins and socket contacts for corrosion or damage before completing the installation.
