Why Choose the Mersen BNIT55V4 BS88 Fuse Link?
The Mersen BNIT55V4 is a compact BS88 gG offset-tag fuse link designed to provide dependable overload and short-circuit protection for low-voltage electrical circuits. Manufactured by Mersen, it delivers effective current limitation to help protect cables, control components, switchgear and connected equipment during electrical fault conditions.
As a general-purpose gG fuse link, the BNIT55V4 provides full-range protection against both sustained overloads and high short-circuit currents. Its offset-tag construction enables secure installation within compatible BS88 fuse holders, fuse-switch disconnectors and industrial control-panel assemblies.
With a rated current of 4 A and an operating voltage of up to 550 V AC, the BNIT55V4 is particularly suitable for control, auxiliary, signalling and low-current distribution circuits where reliable protection and predictable fuse performance are essential.

Reliable Protection for Control and Auxiliary Circuits
The Mersen BNIT55V4 protects electrical installations by interrupting excessive current before it can damage conductors, control devices or connected equipment. During an overload or short circuit, the internal fuse element opens the circuit and limits the amount of fault energy allowed to pass downstream.
Its low 4 A rating makes the BNIT55V4 well suited to sensitive auxiliary and control circuits. Correct coordination with cables, contactors and other protective devices can help improve installation reliability, reduce equipment damage and minimise downtime following an electrical fault.
