What You Get
Low voltage switchgear engineered for the next 30 years, not the last 30.
Every lineup we build, and every lineup we retrofit, includes these by default.
- Smart, paralleling-ready by default
Every lineup we build ships with modern protective relays, digital metering, and paralleling controls already integrated. Sync check, dead-bus closing, load share, and load shed are part of the platform, not an add-on.
- Built to UL 1558
Our low voltage switchgear is listed to UL 1558 for metal-enclosed LV power circuit breaker assemblies, with arc-resistant configurations available where the application calls for it.
- Vendor-neutral architecture
Open protocols (Modbus TCP, DNP3, IEC 61850, BACnet, OPC UA). Documented data models. No proprietary tool required to service the gear. Your team, ours, or any qualified third party can maintain it.
- ControlCom Connect ready
Continuous thermal monitoring, breaker operation counts, alarm trending, and ML-based anomaly detection are available the day the gear is energized, not as a future upgrade.
Where It Fits
Four common LV switchgear scenarios we engineer for.
- New construction
Greenfield LV distribution for healthcare, data centers, utilities, water treatment, and industrial facilities. Engineered around your single-line, fault current, and protection coordination from day one.
- Generator paralleling
Low voltage paralleling switchgear for multi-engine generator plants, base-load operation, peak shaving, and prime-power applications. Utility-grade sync, load share, and transfer logic.
- Retrofit existing lineups
Modernize legacy LV switchgear without replacing the structural assembly. New breakers, new relays, new controls in the cells you already own. Engineered to IEEE C37.59 verification requirements.
- Mission-critical service entrance
Main-tie-main, tie-breaker schemes, and concurrent-maintainability layouts for facilities that cannot accept a single point of failure on the service entrance.
Two Paths to the Same Result
Build new, or modernize what you already own.
For most facilities with structurally sound LV switchgear, retrofit is faster and lower cost. For greenfield work or gear past structural service life, new is the right call. We do both.
Build new
Custom-engineered, factory-built LV switchgear lineups. Sized to your application, coordinated to your fault current, and listed as a complete assembly.
- PE-stamped engineering package: single-line, schematics, layout, sequence of operations
- Factory production test and witnessed acceptance test if required
- Site delivery, install supervision, and commissioning by the engineering team
- Operator training and as-built documentation handoff at energization
Retrofit existing
Modernize the LV switchgear lineup you already own. Reuse the structural assembly. Replace the components that have aged out.
- Walkdown and obsolescence audit of breakers, trip units, relays, and metering
- IEEE C37.59 design verification for retrofitted configurations
- Phased, zero-downtime execution on energized systems
- Arc flash study update and revised NFPA 70E labels at completion

Standards
The codes we build, list, and retrofit to.
- UL 1558
- Metal-enclosed low voltage power circuit breaker switchgear. The listing that governs everything our LV lineups are.
- UL 1066
- Low voltage AC and DC power circuit breakers. The standard for the breakers inside the assembly.
- IEEE C37.20.1
- Metal-enclosed low voltage power circuit breaker switchgear. The performance standard for the assembly itself.
- IEEE C37.20.7
- Arc-resistant switchgear, when an arc-resistant configuration is specified.
- IEEE C37.59
- Design verification for retrofitted circuit breaker equipment. Required for any retrofit we deliver.
- NFPA 70 / 70E
