Description
The Mersen GGA1 is a 1A time-delay miniature glass fuse from the GGA series, engineered to provide reliable supplementary protection for electronic circuits subject to temporary inrush currents or transient overloads. Rated for 250 VAC with a 0.1 kA interrupt rating, its time-delay (slow-blow) characteristic prevents nuisance tripping during motor starts or power-up surges while ensuring safe interruption under sustained fault conditions.
Featuring a compact 5mm x 20mm cylindrical glass construction with nickel-plated brass ferrule terminal connections, the GGA1 allows for straightforward visual inspection of the internal element. It is designed for standard clip mounting in electronic assemblies and control devices.
Key Features
- Time-Delay Protection: Absorbs harmless temporary surge currents and motor startup transients without nuisance blows.
- Visual Inspection: Clear glass body construction enables instant verification of fuse status (blown vs. intact).
- Compact Miniature Sizing: Standard 5mm x 20mm form factor fits tight spaces on circuit boards and in inline holders.
- Nickel-Plated Brass Contacts: Durable terminal connections ensure low resistance and reliable long-term contact performance.
- Global Standards Compliance: Fully RoHS compliant supplementary fuse design.
