Why Choose the Mersen BTIS69V32M40 British Standard Fuse-Link?
The Mersen BTIS69V32M40 is a high-performance British Standard gM fuse-link designed to protect industrial motors and motor control circuits against damaging overcurrents. Its motor-rated operating characteristic accommodates normal starting currents while providing dependable interruption when a serious electrical fault occurs.
Part of the established Mersen BTIS offset tag fuse-link range, the BTIS69V32M40 combines effective current limitation with robust construction for reliable service in demanding industrial environments. By restricting peak fault current and let-through energy, it helps reduce thermal and mechanical stress on motors, cables, contactors and switchgear.
With a 32 A continuous current rating, a 40 A motor circuit rating and an operating voltage of up to 690 V AC, the BTIS69V32M40 is suited to industrial motor applications requiring secure British Standard fuse mounting and dependable high-voltage circuit protection.
