The exact part reference PS201PRE is documented as a Mersen product, formerly associated with Ferraz Shawmut. Mersen references identify F097203 as the manufacturer reference for PS201PRE.

Key Technical Specifications

ABB PS201PRE

The original PS 20 × 127 catalog identifies PS201PRE as the PSI 20 × 127 PRE, reference F097203, with 1-pole construction and a 20 × 127 mm fuse format.

Important Brand Correction

The supplied table says ABB PS201PRE, but the evidence does not support ABB as the manufacturer. is consistently identified as Mersen, with Ferraz Shawmut appearing in older documentation and distributor catalogs.

That distinction matters for procurement, customs documentation, OEM traceability, and replacement qualification.

Product Introduction

Mersen/Ferraz Shawmut 1-pole fuse disconnect holder designed for cylindrical 20 × 127 mm fuses. It provides a disconnecting function for high-voltage fuse applications and is rated at 1,500 V AC/DC with a 63 A rating in distributor documentation.

The PRE version is supplied with contact protection but without the optional microswitch. For semiconductor protection, inverter, and other high-speed fuse circuits, the fuse-holder rating and utilization category must be matched to the actual fuse and installation arrangement.

Application Scenarios & Pain Points

A fuse holder at this voltage level is not simply a mechanical accessory. The holder must match the fuse envelope, voltage class, current rating, mounting arrangement, and required isolation function.

Typical Applications

1. Power electronics and inverter protection
   The 20 × 127 mm format is used with cylindrical high-speed fuses commonly found in semiconductor and converter protection circuits.
2. DC-link and industrial power equipment
   The 1,500 V DC rating makes the product relevant to higher-voltage DC protection systems where conventional low-voltage fuse holders are unsuitable.
3. Industrial control and power cabinets
   The panel-mounted construction allows the holder to be integrated into fixed electrical assemblies rather than DIN-rail control circuitry.
4. Maintenance of legacy Ferraz/Mersen installations
   When replacing an installed holder, matching the reference is safer than selecting another 20 × 127 holder solely by physical dimensions.

Engineering Note

One detail worth checking in the field: is the version without a microswitch. The PS201PREMCPS family, by comparison, incorporates microswitch functionality. These variants should not be treated as electrically identical.

Compatibility & Replacement Matrix

Procurement warning: I would not publish this item as an ABB-manufactured component without a physical nameplate or ABB document supporting that attribution. The strongest available documentation identifies Mersen / Ferraz Shawmut as the manufacturer.
