Bussmann Switched Pole Kit, Three-to-Four-Pole Switch Accessory
The Bussmann Switched Pole Kit is a switch accessory engineered to convert a three-pole switch into a four-pole switch, adding flexibility to existing disconnect and safety switch installations without requiring a full switch replacement. This compact, RoHS compliant accessory is available in 16A and 40A ratings to match a range of switch capacities, and its small footprint allows it to install cleanly into existing switch enclosures without added bulk. Backed by the Bussmann name, it is built for dependable performance in commercial and industrial electrical systems where field flexibility and code-compliant components matter.
Key Features
- Pole Conversion: Converts a three-pole switch to a four-pole switch, expanding circuit control without replacing the entire switch assembly.
- Amp Rating Range: Offered in 16A and 40A ratings, allowing selection to match the amperage of the host switch.
- Compact Construction: Measures 2.63 IN in length, 2.51 IN in height, and .74 IN in width, with a light .12 LB weight for easy handling and installation.
- RoHS Compliant: Manufactured to RoHS compliance standards for environmentally responsible electrical installations.
- Special Feature: Purpose-built to convert three-pole switches to four-pole switches, simplifying field upgrades of existing disconnect switches.
- Space-Saving Fit: The compact .74 IN width helps the added pole fit within standard switch enclosure footprints during retrofits.

Bussmann POLE-16 – Frequently Asked Questions
1) What does the Bussmann switched pole kit actually do to a three-pole switch?
It adds a fourth switched pole to an existing three-pole switch, so you get four-pole circuit control without swapping out the whole switch assembly. That makes it a field upgrade part for disconnect and safety switches already installed, typically where a switched neutral or a fourth phase leg becomes necessary after a circuit change.
2) Which amp rating of the Bussmann pole kit do I order, 16A or 40A?
Match the kit to the amperage of the host switch. Two ratings are offered: the 16A kit (POLE-16) and the 40A kit (POLE-40). If the switch you are adding the pole to is a 40A frame, the 16A kit is the wrong part, and vice versa. The overall range covered across both is 16A to 40A.
3) Is it cheaper in labor to add this pole kit or just replace the whole disconnect switch?
The whole point of the kit is to avoid pulling the switch. It bolts a fourth pole onto the three-pole assembly you already have, so the existing enclosure, mounting and incoming feeders stay put and you are only terminating the new pole. Replacing the switch means new enclosure prep and re-terminating every conductor. If the host switch is sound and its amperage matches a 16A or 40A kit, the accessory route is the shorter job.
4) Can this pole kit be added to any brand of three-pole switch?
Treat it as a Bussmann switch accessory intended for Bussmann switch assemblies. It is sold by host switch amperage, 16A or 40A, and the pole module has to stack onto the existing three-pole mechanism, so the switch it goes on has to be built to accept it. Confirm the kit against the model of the switch you are upgrading before you order.
5) Does the Bussmann switched pole kit meet RoHS for our facility spec?
Yes, the switched pole kit is RoHS compliant, which is the compliance point stated for it. For institutional and government specs that call out restricted substances on electrical components, that requirement is satisfied.
6) What kind of jobs is this three-to-four-pole kit normally used on?
Safety switch pole conversions, panelboard and disconnect switch upgrades, and renovation or retrofit work where the circuit changed after the original switch went in. Commercial and industrial installs are the usual setting, which is where a crew wants to adapt existing switch infrastructure rather than source a new switch assembly.
