Why Choose the Mersen BTIS69V32M63 Motor Circuit Fuse Link?
The Mersen BTIS69V32M63 is a high-performance BS88 gM Type A3 offset-tag motor fuse link designed to provide dependable short-circuit protection for motors, motor starters and associated industrial control equipment. Manufactured by Mersen, it complies with EN 60269-2 and BS 88 Part 2 and is engineered specifically for motor protection applications requiring reliable fault interruption and excellent current limitation.
Unlike general-purpose gG fuse links, the BTIS69V32M63 features a gM operating characteristic, allowing it to withstand the high inrush currents associated with motor starting while rapidly disconnecting dangerous short-circuit faults. This makes it ideal for protecting motors when coordinated with a suitable overload relay.
With a 32M63 motor rating, 690 V AC and 460 V DC voltage ratings, and a robust Type A3 offset-tag construction, the BTIS69V32M63 is suitable for motor control centres, industrial machinery, OEM panels and heavy-duty electrical installations.
