Overview

The Mersen TI-130 (SKU: TI-130) is a field-mountable blown-fuse indicator designed for reliable detection and signaling of fuse operation in industrial electrical systems. Wired in parallel with the fuse it monitors, this Mersen accessory provides immediate notification when a fuse blows. Its key feature is a striker pin that exerts a static force of one pound, capable of actuating an external switch for remote annunciation or automated control actions. This is crucial for preventing equipment damage and ensuring operational continuity in critical circuits. The TI-130 is rated for 130 Volts and is suitable for use with fuses rated at 70 Amps or higher. This makes it a versatile solution for higher current industrial applications. While not a fuse itself, it is designed to be used in conjunction with fuses of appropriate rating. Installation involves using two midget fuse clips (for 13/32” diameter fuses) as specified in the fuse clip section of Mersen's catalog. Key Features and Benefits: * **Reliable Blown Fuse Detection:** Provides visual or switch-actuated notification of fuse operation. * **Field-Mountable Design:** Easy installation directly onto electrical panels or equipment. * **Switch Actuation:** Striker pin exerts one pound of force to trigger external switches. * **Voltage and Current Compatibility:** Rated for 130V and compatible with 70A+ fuses. * **Enhanced System Safety:** Minimizes downtime and potential damage by alerting operators to blown fuses promptly. Applications include supplemental protection for circuits where time-delay and blown fuse indication are essential, such as critical solenoid circuits, control circuits, and industrial machinery. The TI-130 improves diagnostic capabilities and supports proactive maintenance in demanding industrial environments. The TI-130 has a length of 2 inches.
