The program is designed for dead-front switchboards rated at 600 volts or less and circuits having available rms symmetrical short-circuit currents no greater than 200 kA. Typical applications for these switchboards are electrical light and power circuits. The Tmax Link OEM UL 891 Switchboard Program provides an extension of ABB’s UL certification under which manufacturers may fabricate basic components using their own branding. The program includes extension procedures that facilitate the formal process for UL 891 compliance of chassis and enclosures. The extension package also includes 2-D and 3-D drawings to aid design and engineering.

The Tmax Link distribution switchboard design incorporates features that meet application requirements for high short-circuit systems, while remaining flexible, safe and convenient. Other benefits of the Tmax Link OEM UL 891 Switchboard Program include coverage of 1 1/4 - and 1 3/8-in. hole spacing on the vertical bus and up to 1,200-A frame breaker in 32-in. width section.

In addition to drawings and compliance procedures, the Tmax Link OEM UL 891 Switchboard Program extension package includes assembly instructions, with torque values, and a bill of materials. Optional breaker mounting kits are also available.
