Siemens HBB612 Load Base 30A 600V Hdds

Product Description

The SIEMENS HBB612 is a fusible disconnect load base rated for 30 amps and 600 volts, designed for use with HDDS-series disconnect switches. It provides a secure, code-compliant mounting and connection point for the load side of a disconnect assembly. The base accepts fused or non-fused inserts and is built to handle industrial and commercial power distribution applications. Licensed electricians and electrical contractors install this component as part of a complete disconnect assembly, typically in panel boards, motor control circuits, or equipment disconnects where service isolation is required.

The HBB612 load base is used in commercial and industrial electrical systems where a robust fusible disconnect point is needed. It is suited for motor branch circuits, HVAC equipment disconnects, and similar load-side applications requiring a 30-amp, 600-volt rated base. The HDDS series designation indicates compatibility within the Siemens heavy-duty disconnect switch product family. Installations are found in manufacturing facilities, mechanical rooms, and commercial construction projects where NEC-compliant disconnect means are required at equipment.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before handling any disconnect components. Verify that the load base rating matches the circuit ampacity and voltage before installing fuses or completing wiring connections. Do not exceed the 30-amp or 600-volt ratings under any operating condition.
