Why Choose the Mersen BTIS42V63M80 BS88 Offset Tag Motor Fuse?
The Mersen BTIS42V63M80 is a high-performance BS88 gM offset tag fuse-link designed to provide dependable short-circuit protection for industrial motors and associated electrical equipment. Its motor-duty operating characteristic accommodates the temporary inrush currents produced during motor starting while rapidly interrupting dangerous fault currents.
As part of the established Mersen BTIS motor fuse-link range, the BTIS42V63M80 offers effective current-limiting performance that helps reduce thermal and mechanical stress on contactors, cables, switchgear and connected machinery during a short circuit. This supports improved installation safety, reduced equipment damage and greater operational continuity.
Featuring a 63M80 motor fuse rating and voltage ratings of 415 V AC and 240 V DC, the BTIS42V63M80 is suitable for motor starters, motor control centres, industrial machinery and OEM control panels. Its offset tag configuration enables secure installation in compatible BS88 fuse holders and switch-fuse assemblies.
