Material & Design Characteristics

• Integrated Cartridge: Precision engineered integrated element and cartridge design to avoid manual field assembly errors.
• Contacts System: Premium silver-plated flared contacts and end contacts to ensure precise current-carrying characteristics.
• Hardware Fit: Heavy-duty solid brass end plug securely staked to prevent accidental removal during harsh field operations.

Product Functions

1. Protect Transformers from Overload Damage: Protects both single-phase and three-phase distribution apparatus from damaging currents and distribution systems from failed apparatus.

2. Two-Stage Protection Scheme: Ideal for series coordination with a current-limiting backup fuse (such as ELSP). The Bay-O-Net fuse clears secondary faults and overload currents, while high-level internal faults are cleared by the backup fuse.

3. Advanced Heat Dissipation: Specially engineered to lower operating temperatures and provide better heat dissipation at higher load current levels, extending Bay-O-Net applications to larger kVA units.

Key Features

1. Integrated Cartridge Design: Features an integrated fuse link and cartridge design specially engineered to reduce operation temperatures and avoid field assembly errors.

2. Easy Hotstick Operation: No special tools required. The entire fuse cartridge can be easily replaced in the field using a standard hotstick from non-pressurized apparatus.

3. Silver-Plated Contact Design: Features silver-plated flared contacts and end contacts to ensure intended operating characteristics when used in silver-plated Flapper™ valve Bay-O-Net assemblies.

4. Staked Brass End Plug: Equipped with a heavy-duty brass end plug that is securely staked to prevent accidental removal during operation.
