Why Choose the Mersen Y233563 Medium-Voltage Fuse Base?
The Mersen Y233563, also identified as SI85-36-1902MCT and SI 85-36.190 + MC2R 1-5 TRAC, is a robust medium-voltage fuse base assembly designed to securely mount compatible cylindrical high-voltage fuse-links. It provides dependable mechanical retention, electrical contact and fuse-operation monitoring within transformer, switchgear and power-distribution installations.
Manufactured by Mersen, formerly known as Ferraz Shawmut, this fuse base is designed for 36 × 190 mm cylindrical fuse-links. The assembly incorporates a micro-contact arrangement that can provide remote indication or interface with compatible control and monitoring equipment when the installed fuse operates.
With a rated voltage of up to 7.2 kV AC/DC and a continuous current rating of up to 100 A, the Mersen Y233563 is suitable for demanding medium-voltage applications. Its secure M8 connection points and durable insulating construction support reliable operation within appropriately enclosed electrical equipment.

Reliable Fuse Mounting and Status Monitoring
A correctly specified fuse base is essential for maintaining secure mechanical support and low-resistance electrical contact around a medium-voltage fuse-link. The Mersen Y233563 holds the fuse-link securely while allowing replacement during maintenance after the circuit has been safely isolated.
The integrated MC2R micro-contact can be used with a compatible operated-fuse mechanism to provide status indication to switchgear controls, alarms or monitoring systems. This helps maintenance teams identify an operated fuse more quickly and supports efficient fault diagnosis within critical electrical installations.
Typical Applications
- Medium-voltage switchgear assemblies.
- Transformer protection systems.
- Public lighting distribution equipment.
- Industrial electrical distribution installations.
- Utility and infrastructure power systems.
- Fuse-operation monitoring and alarm circuits.
