Trigger Indicator

The Trigger Indicator is part of the Mersen (formerly Ferraz Shawmut) semiconductor fuses line, distributed by Gross Automation.

The Trigger Indicator (Catalog Number suffix TI) is available on many blade type fuses, primarily Form 101 semiconductor fuses and some Class L fuses. The TI allows blown fuses to be identified visually, eliminating the need for resistance or continuity testing.
