Verified on the Physical grid

Electrical contractors and facility managers don't guess. They install TOMZN because our breakers, protectors, and changeovers are certified to perform under continuous load.

Performance under load

From commercial job sites to industrial control panels, our hardware is tested by those who risk their reputation on every installation.

The 63A changeover switches handle our continuous thermal current without any heat buildup. Terminal screws are heavy-duty and don't strip under torque.

Marcus G., Industrial Electrician

We've deployed over eighty of their volt-ampere protectors across our commercial projects this year. The over-voltage thresholds trip exactly at the rated limit.

Dave Y., Facility Manager

Same-day shipping saved our schedule on the Houston warehouse job. Ordered at 2 PM, parts arrived on-site the next morning. Zero-latency switching is flawless.

No sales calls or quote-free waiting. We buy directly from the hub, download the datasheets instantly, and pass the savings on to our clients.
