Siemens WL Breakers

✓ Authorized Siemens distributor

✓ Hard-to-find and manufacturer-specific equipment

✓ Since 1972

Specifying Siemens WL breakers is easier than finding one on short notice. Distribution gear from Siemens has come through Bud Ferguson's Industrial Control & Supply Inc. since 1972. Purchasers in all fifty states reach the same shelf for Siemens WL breakers and the accessories they need. Authorized distribution is what puts current frames and hard-to-find parts under one roof.

Advantages Siemens WL Breakers Bring to Low-Voltage Switchgear

Protection and metering happen inside the breaker with Siemens WL breakers, rather than through separate devices bolted around the frame. Rogowski current transformers built into the frame handle both jobs at once. Extended Instantaneous Protection lets a unit run at full withstand while still applied up to its maximum interrupting rating. Communications capability means the breaker reports into a higher-level energy management system instead of staying blind. Certification runs to UL 1066, and performance testing follows the ANSI C37 series.

Frames, Mountings, and Accessories in Our Inventory

Coverage runs from 800 through 6000 amps, across frame sizes II and III, which marks the working range of our Siemens WL breakers. Lineups installed before this design usually run the insulated case family, where Siemens SBS2020F covers a 2000 amp frame. Draw out and fixed mount versions are both stocked, with the cradles and trip units each arrangement needs. Requirements of 800 amps on a 2000 frame point to Siemens SBH2008F, since only the SBH type offers that pairing. Interchangeable rating plugs let one frame serve several ampere values, which stretches a single unit across more applications. Smaller feeders take molded case gear instead. MD63B800 covers 800 amps at 25 kAIC on 600 volts. WL accessories are stocked in their own category, so a missing part does not force a whole new breaker.

Sourcing a Line the Factory Has Discontinued

Discontinuation is where Siemens WL breakers get difficult, because a switchgear lineup outlives the catalog that produced it. Half a century of stocking has left frames and accessories in our warehouse that the factory no longer lists. Several generations of Siemens design are represented in our industrial circuit breakers inventory. Reconditioned units clear inspection and testing before shipping, and a test report travels with each one. Modification to a customer's specification handles cases where a standard build will not drop into an existing cubicle.

Order the WL Frame Your Switchgear Takes

Power stays off in a lineup until someone locates the correct Siemens WL breakers. Mounting style, trip unit, and ampere rating narrow the search to a single part number. Everything from the frame to the trip unit inside it comes through our electrical equipment supplier. Shipments leave one warehouse for destinations throughout the country, whatever the lineup looks like. Give us the ratings from the existing unit and we will quote the WL frame your switchgear takes.
