Why Choose the Mersen BTMF42V355 Industrial Fuse Link?
The Mersen BTMF42V355 is a heavy-duty industrial bolted-tag fuse link designed to provide dependable protection for high-current, low-voltage electrical systems. Manufactured by Mersen, it helps protect cables, busbars, switchgear and connected equipment against potentially damaging overcurrent and short-circuit conditions.
With a rated current of 355 A and an operating voltage of up to 415 V AC, the BTMF42V355 is suited to demanding power-distribution and motor-control installations. Its robust bolted-tag construction provides a secure electrical and mechanical connection within compatible fuse holders, fuse-switch disconnectors and industrial switchgear assemblies.
The BTMF42V355 offers effective current limitation during severe electrical faults, helping to reduce peak fault current, let-through energy and stress on downstream equipment. It is a practical choice for electrical engineers, panel builders and maintenance teams requiring reliable circuit protection in industrial environments.

Reliable Protection for High-Current Electrical Systems
The Mersen BTMF42V355 operates by interrupting excessive current before it can cause serious thermal or mechanical damage to conductors, switchgear and connected machinery. During a severe short circuit, its current-limiting action helps restrict the peak current and electrical energy passed through the protected circuit.
Correct fuse selection and coordination with cables, contactors, overload devices and other protective equipment can improve installation safety and system reliability. The BTMF42V355 should always be installed in compatible equipment with suitable current, voltage and fault-level ratings.
