Overview

The Mersen TI-600 Trigger Indicator (SKU: TI-600) is a UL Listed, field-mountable accessory designed for immediate and accurate blown-fuse detection in industrial electrical systems. Wired in parallel with the fuse it monitors, this device provides a clear indication when a fuse has operated, preventing downtime and potential equipment damage. The TI-600 is specifically designed for use with Mersen Form 101 high-speed fuses and select Class L fuses, requiring a minimum fuse rating of 70 Amps or higher and operating within 600V systems. This makes it an essential component for high-power distribution in manufacturing, power generation, and data center environments. Key features include a striker pin that exerts a static force of one pound, enabling it to actuate auxiliary switches, alarm systems, or control mechanisms upon fuse failure. The TI-600 is not a fuse itself but a monitoring accessory. For installation, two midget fuse clips (for 13/32” diameter fuses) are required, available separately in the Mersen fuse clip section. The device's design eliminates the need for resistance or continuity testing to identify blown fuses, streamlining maintenance and troubleshooting. Its robust construction and field-mountable design facilitate easy retrofitting and new installations. By providing rapid blown fuse identification, the TI-600 minimizes unexpected shutdowns, reduces the risk of cascading failures, and protects valuable machinery from electrical faults. Its 2-inch length is suitable for various fuse configurations.
