Connection Block 021000400

The connection block (part# 021000400) is the genuine Lindhaus electrical connection block that joins wiring between sections of the machine. It provides a secure, organized junction for the power and control conductors.

Because it carries the machine’s wiring junctions, the block is central to reliable operation, and heat or vibration can loosen or damage it over time. Intermittent power, a machine that cuts out, or scorched terminals all point to a junction that should be replaced.

This is an electrical part best fitted by a qualified technician who can match the wiring exactly. Browse cords, switches, and related electrical parts in the full Lindhaus vacuum parts catalog.

This connection block fits the Lindhaus PB12, PB12e, PB14, PB14e, and RX Hepa. Twin City Vacuum has been selling and servicing Lindhaus equipment since 1956, and our team at 5415 West Broadway, Crystal, MN 55428 can help confirm the right part for your machine. You can also review your model at Lindhaus.

A genuine Lindhaus terminal is rated for the machine’s current and molded to the original footprint, so the wiring reconnects cleanly without improvised splices. Using the factory part keeps the electrical junction safe, tidy, and reliable through years of service.
