The Mersen BTIS42V63M100 is a dependable motor-rated industrial fuse link designed to provide short-circuit protection for motors, cables, contactors and associated electrical equipment. Manufactured by Mersen, this fuse is intended for industrial motor circuits where reliable fault interruption and effective coordination with motor-starting equipment are essential.
Its 63M100 motor-circuit rating is designed to tolerate the temporary inrush current produced when an electric motor starts while still responding rapidly to damaging short-circuit currents. This helps prevent unnecessary fuse operation during normal starting conditions without compromising protection against serious electrical faults.
With a rated voltage of 415 V AC, the BTIS42V63M100 is suitable for compatible low-voltage industrial installations. Its bolted-tag construction enables secure mounting within an appropriately rated fuse carrier, switch-fuse assembly or motor-control panel.
Electric motors can draw several times their normal operating current during starting. A conventional fuse selected only according to the motor’s running current may operate unnecessarily during this temporary inrush. Motor-rated fuse links are designed to withstand normal starting conditions while providing rapid protection against high-level electrical faults.
The Mersen BTIS42V63M100 is typically used alongside a correctly selected overload relay or motor-protection device. The fuse provides short-circuit protection, while the overload device protects the motor against prolonged overcurrent conditions. Correct selection should consider the motor rating, starting method, starting duration, cable capacity and prospective fault current.

The BTIS42V63M100 is used to provide short-circuit and fault-current protection for industrial motors, cables, contactors and motor-control equipment.
The 63M100 designation identifies a motor-rated fuse with a 63 A current rating and characteristics that allow it to accommodate normal motor-starting currents within the associated 100 A fuse-link size.
The Mersen BTIS42V63M100 is rated for operation in compatible electrical systems up to 415 V AC.
The fuse is primarily intended to provide short-circuit protection. A correctly selected overload relay or motor-protection device is normally required to protect against prolonged motor overloads.
No. The BTIS42V63M100 is a non-resettable fuse link and must be replaced with a correctly rated equivalent after it has operated.
Mersen motor-rated fuse links are used by electrical engineers, panel builders and maintenance professionals to provide reliable short-circuit protection for industrial motors and control equipment.
