Mersen 30310 Add-a-fuse Fuse Block 30A 600V

Product Description

The MERSEN 30310 is an add-a-fuse fuse block rated for 30 amps and 600 volts, designed to expand overcurrent protection capacity in electrical distribution systems. This fuse block mounts alongside existing fusible equipment, allowing technicians to add a protected circuit without replacing the primary disconnect or panel. It is a standard component in commercial and industrial electrical work, installed by licensed electricians wherever branch circuit fusing needs to be added or supplemented within a panelboard or disconnect enclosure.

The 30310 is suited for use in commercial buildings, light industrial facilities, and equipment panels where additional fusible branch protection is required. It is commonly installed in applications where the existing disconnect or distribution block does not include enough fuse positions for all required circuits. The 600-volt rating makes it appropriate for both single-phase and three-phase distribution environments operating at standard utilization voltages.

Key Features

• 30-amp continuous current rating for branch circuit overcurrent protection
• 600-volt rating suitable for single-phase and three-phase systems
• Add-a-fuse design allows circuit expansion without replacing primary equipment
• Compact fuse block form factor for installation within existing enclosures

Compatibility

Designed as an OEM-style add-a-fuse replacement or expansion block for use in standard electrical distribution panels and disconnect enclosures rated to 600 volts and 30 amps.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Always de-energize and lockout/tagout the circuit before installing or servicing any fuse block. Verify that the upstream overcurrent device and conductors are appropriately sized for the 30-amp rating before energizing. Do not install fuses with a rating exceeding the block's marked current and voltage ratings.
