Why Choose the Mersen BNIT55V25M32 BS88 Offset Blade Motor Fuse?
The Mersen BNIT55V25M32 is a reliable BS88 gM offset blade fuse-link designed to provide short-circuit protection for motors and associated equipment in industrial low-voltage electrical systems. Its motor circuit operating characteristic allows the temporary inrush currents produced during motor starting while rapidly interrupting dangerous fault currents.
As part of the established Mersen BNIT motor fuse-link range, the BNIT55V25M32 offers effective current-limiting performance that helps reduce thermal and mechanical stress on contactors, cables, switchgear and other downstream components. Its robust construction supports dependable protection in demanding industrial control and power distribution environments.
Featuring a 25M32 motor fuse rating and voltage ratings of 550 V AC and 250 V DC, the BNIT55V25M32 is suitable for motor starters, control panels, machinery and OEM equipment. Its offset blade configuration enables secure installation within compatible BS88 fuse holders and switch-fuse assemblies.
