Overview

The Mersen GMSD alarm indicating fuse (SKU: GMSD) is designed for supplemental protection in circuits requiring time-delay and blown fuse indication. This fuse features a pin indicator that visually signals when the fuse has operated, or can be used to actuate a switch for remote annunciation. It offers a 12-second time-delay at 200% of its rating. The GMSD series is available in 19 ampere ratings, filling diverse replacement needs. These fuses are not intended for branch circuit protection. Key specifications include various voltage ratings depending on the ampere range: 250VAC for 0.1-10A, 125VAC for 12-15A, and 32VAC for 20-30A. Interrupting ratings vary by voltage and amperage, with up to 200kA I.R. at 250VAC for 0.1-10A ratings, 10kA I.R. at 125VAC for 0.1-15A, and 10kA I.R. at 32VAC for 20-30A. The GMSD fuses have dimensions of 1-1/2" x 13/32" (10 mm x 38 mm). They are UL Listed to standard 248-14 (1/10 to 15A) and CSA Certified to Standard C22.2 No. 248. Applications include solenoid circuits and control circuits where time-delay and blown fuse indication are essential. The color-coded flag system simplifies identification and reduces human error during maintenance. Mersen's GMS series fuses are built with quality materials for reliable service in industrial and telecommunications environments.
