Overview

Mersen GFN6 is a 6A time-delay midget fuse with a built-in visual indicator for blown fuse detection. Designed for supplemental protection in control and solenoid circuits, this 250VAC ferrule fuse operates with a 12-second delay at 200% of rated current, ensuring reliable performance in transient conditions. The integrated pin indicator pops out at the end of the fuse to provide immediate visual confirmation of an open circuit, which can also be used to actuate remote switches for additional signaling. With a compact 1 1/2" x 13/32" (10 mm x 38 mm) footprint, the GFN6 is compatible with UltraSafe™ fuse holders for 1/10 to 10A ratings, making it ideal for space-constrained applications. Rated at 200kA interrupting rating (IR) for 250VAC, this UL Listed (File E33925) and CSA Certified fuse is engineered for supplemental protection where time-delay and indication are critical. Not intended for branch circuit protection.
