Mersen GGM1/2 Fast-Acting Fuse 250V 0.5A 5x20mm Glass Body

Description

Features

• The Mersen GGM1/2 is a fast-acting miniature fuse specifically engineered to react instantly to overcurrent spikes. This rapid response is critical for protecting delicate printed circuit boards (PCBs) and precision instruments where even a millisecond of excess current could cause permanent component failure.
• Designed in the widely adopted 5mm x 20mm "metric miniature" size, this fuse is the go-to standard for modern consumer electronics, power supplies, and medical devices. Its compact footprint allows for high-density circuit protection in tight spaces where traditional 1/4" x 1-1/4" fuses simply won't fit.
• Rated for 1/2 Amp at up to 250 Volts AC, the GGM1/2 provides precise supplemental protection for low-current devices. This ensures that the fuse remains stable during normal operation while providing a reliable "weak link" that breaks the circuit safely if a fault occurs, preventing fire hazards and further equipment damage.+
• eaturing a high-clarity glass tube construction, this fuse allows for immediate visual inspection of the internal filament. This "look-and-see" diagnostic saves valuable troubleshooting time for technicians and maintenance engineers, as a failed fuse can be identified at a glance without needing a multimeter.
