We stock and build Siemens low voltage switchboards from 1600A to 4000A and ship nationwide, often inside 24 to 48 hours. Whether you are replacing a damaged service entrance, expanding a commercial facility, or specifying gear for a new industrial install, our team can match the original Siemens configuration and get it on the truck while other suppliers are still confirming material availability.\u003c\/p\u003e\n\n\u003cp\u003eVerified Breakers carries Siemens SB1, SB2 and SB3 front-connected switchboards alongside reconditioned and surplus units. Every assembly is tested, labeled, and built to your single-line drawing. Send us your specs and we will quote within hours.\u003c\/p\u003e\n\n\u003ch2\u003eThe Siemens Switchboard Range We Stock\u003c\/h2\u003e\n\n\u003cp\u003eSiemens manufactures one of the deepest low voltage switchboard lines in North America, and we hold inventory across the most-requested variants. Our active stock covers front-connected designs rated up to 4000A on the main bus and custom builds up to 6000A through our fabrication partners.\u003c\/p\u003e\n\n\u003cp\u003eConfigurations we routinely supply:\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSB1 switchboards\u003c\/strong\u003e for limited-space service entrance applications up to 2000A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSB2 switchboards\u003c\/strong\u003e with added capacity up to 4000A, supporting insulated case and molded case breakers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSB3 switchboards\u003c\/strong\u003e custom-configured for high-fault industrial sites up to 6000A\u003c\/li\u003e\n  \u003cli\u003eGroup-mounted distribution sections with MCCBs from 100A through 1200A\u003c\/li\u003e\n  \u003cli\u003eService entrance sections with main breakers, ground fault protection and metering compartments\u003c\/li\u003e\n  \u003cli\u003eNEMA 1 indoor and NEMA 3R outdoor enclosures, including seismically qualified options\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eEach Siemens switchboard we ship is built to UL 891 and NEMA PB-2 standards.

These are the assemblies most facilities specify for main service, sub-distribution and large mechanical loads. We carry the breakers, bus, and structural sections to build any standard amp rating from stock and have shipped emergency replacements for every size in this range.\u003c\/p\u003e\n\n\u003ch3\u003e1600A and 2000A Siemens Switchboards\u003c\/h3\u003e\n\n\u003cp\u003eThe 1600A and 2000A class covers the bulk of commercial service entrance work. Typical builds are 480Y\/277V, 3-phase 4-wire, with a main disconnect or main breaker section and three to five distribution sections. We supply these with fused disconnects, bolted-pressure switches, or WL insulated case breakers depending on your interrupting requirement. Standard interrupting ratings of 65kAIC and 100kAIC are kept on the shelf.\u003c\/p\u003e\n\n\u003ch3\u003e2500A Siemens Switchboards\u003c\/h3\u003e\n\n\u003cp\u003e2500A switchboards bridge commercial and light industrial demand. Common use cases include healthcare campuses, multi-tenant office buildings, and mid-size manufacturing plants. We build these in SB2 frames with mains-only or main-and-distribution configurations, with the option to add metering, surge protection, and ground fault relay packages.\u003c\/p\u003e\n\n\u003ch3\u003e3000A and 4000A Siemens Switchboards\u003c\/h3\u003e\n\n\u003cp\u003eThe 3000A and 4000A range is where data centers, hospitals, and heavy industrial sites typically specify. These assemblies use Siemens WL insulated case circuit breakers or RL-frame power breakers as the main, with extra-depth distribution sections to accommodate higher-capacity bussing. We stock the structural sections, copper bus, and WL trip units required to build at this rating without waiting on factory shipments.\u003c\/p\u003e\n\n\u003ch2\u003eVoltage and Configuration Options\u003c\/h2\u003e\n\n\u003cp\u003eMost Siemens switchboards we sell are rated 480Y\/277V or 208Y\/120V, 3-phase 4-wire. We also build 240V delta and 600V Canadian-spec switchboards when projects call for them. Configurations are flexible: main breaker, main lug only (MLO), service entrance rated, or sub-distribution. Tell us what the upstream feeder looks like and we will configure the switchboard to match.\u003c\/p\u003e\n\n\u003cp\u003eCommon configuration combinations we build to order:\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eService entrance with utility metering compartment and main breaker\u003c\/li\u003e\n  \u003cli\u003eMain lug only distribution for downstream feeders\u003c\/li\u003e\n  \u003cli\u003eDouble-ended switchboards with tie breaker for redundant supply\u003c\/li\u003e\n  \u003cli\u003eIntegrated ground fault protection with 1200A and larger mains\u003c\/li\u003e\n  \u003cli\u003eSurge protection device sections for sensitive electronic loads\u003c\/li\u003e\n  \u003cli\u003eFuture-space sections sized for known expansion\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eMain and Distribution Section Specifications\u003c\/h2\u003e\n\n\u003cp\u003eEvery Siemens switchboard we ship includes documentation that matches what your electrical contractor and AHJ expect to see. That covers single-line diagrams, breaker schedules, nameplate data, and test reports for the as-built assembly. We label every section, mark breaker positions, and confirm phase rotation before the unit leaves our facility.\u003c\/p\u003e\n\n\u003cp\u003eOn the breaker side, we hold inventory of Siemens FD, HFD, JD, HJD, LD, HLD, MD, and HMD frames for distribution sections, plus WL and RL power breakers for mains. If you need a specific trip unit, communications module, or shunt trip accessory, name it on the quote and we will confirm availability before pricing.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy Siemens Switchboards From Verified Breakers\u003c\/h2\u003e\n\n\u003cp\u003eOur entire business is built around one number: 24 to 48 hour turnaround when manufacturer lead times are 20+ weeks. That is the gap we close.
