Designed to UL 891; UL (cULus) / CSA certifiable. Entogo designs and builds the Low-Voltage Switchboard (UL 891) in its own factory with a vertically integrated supply chain: this product ships in 12–18 weeks (new UL or CSA certification can extend that, within a guaranteed 36-week worst case), and every Entogo product carries a minimum 36-month manufacturer warranty. This **dead-front low-voltage switchboard** handles service-entrance and feeder distribution on **≤ 600 V**, 60 Hz systems, with bus ratings from **800 to 6000 A** and short-circuit ratings to 200 kA. Group-mounted molded-case or insulated-case breakers give a flexible, sectionalized layout, and a service-entrance-rated configuration with metering provisions handles the utility tie-in for commercial, institutional and industrial buildings. It offers high breaking capacity, good dynamic and thermal stability and a compact structure that fits building electrical rooms, in NEMA 1 indoor or 3R outdoor enclosures. Designed and built to **UL 891** with molded-case breakers to UL 489, and UL (cULus) / CSA certification available on request. ## Key features - Dead-front switchboard for service-entrance and feeder distribution, designed and built to UL 891, 60 Hz — UL (cULus) / CSA certification available on request. - 800 – 6000 A bus with short-circuit ratings to 200 kA and good dynamic / thermal stability. - Group-mounted molded-case or insulated-case breakers; flexible, sectionalized layout. - Service-entrance-rated configuration with metering provisions for utility tie-in. - NEMA 1 indoor or 3R outdoor enclosure; compact structure sized for building electrical rooms.

Drawout UL 1558 switchgear is a higher tier for mission-critical systems needing 30-cycle withstand and withdrawable breakers. - **What ratings and standards apply?**: ≤ 600 V, 800 – 6000 A, up to 200 kA short-circuit, 60 Hz, with a service-entrance-rated option.
