Why Choose the Mersen BTIS42V50 Industrial Fuse Link?

The Mersen BTIS42V50 is an industrial fuse link designed to provide dependable overcurrent protection in low-voltage electrical systems. Manufactured by Mersen, it helps protect cables, conductors, switchgear and connected equipment by disconnecting the circuit when current rises beyond safe operating limits.

Suitable for industrial power distribution and control applications, the BTIS42V50 supports reliable fault protection where electrical safety and equipment continuity are essential. Its current-limiting operation can help reduce the peak current and electrical energy passing through downstream components during a serious short-circuit condition.

With a rated current of 50 A and a voltage rating of up to 415 V AC, the BTIS42V50 is suitable for distribution panels, control systems, industrial machinery and other electrical installations. It should be installed in compatible fuse equipment selected for the fuse link’s electrical rating and physical configuration.

Key Advantages

  • Dependable protection for industrial electrical circuits.
  • 50 A rated current for distribution and equipment applications.
  • 415 V AC rating for low-voltage electrical systems.
  • Helps protect cables, conductors and connected equipment.
  • Current-limiting operation can reduce damaging fault energy.
  • Suitable for use in compatible industrial fuse equipment.

Key Features

  • Mersen BTIS industrial fuse-link range.
  • 50 A rated current.
  • 415 V AC rated voltage.
  • Designed for industrial overcurrent protection.
  • Current-limiting fault interruption.
  • Suitable for power distribution and control circuits.
  • Compatible with correctly rated fuse holders and switching equipment.
  • Designed for dependable service in industrial electrical installations.

Reliable Protection for Industrial Electrical Systems

The Mersen BTIS42V50 is designed to disconnect a protected circuit when excessive current creates a risk to conductors and connected equipment. This helps reduce overheating and limits the potential for damage to switchgear, machinery and other electrical components.

During a high-level electrical fault, the fuse can restrict the peak current and total energy passing through the protected circuit. Correct coordination with the associated fuse holder, switching device, cable and downstream equipment is essential for safe and reliable operation.

Typical Applications

  • Industrial power distribution systems.
  • Electrical switchboards and distribution panels.
  • Control panels and automation equipment.
  • Cable and conductor protection.
  • Industrial machinery and production equipment.
  • Compatible fuse holders and fused switching devices.
