ABB Switchboard program

The Tmax Link OEM UL 891 switchboard program enables OEMs to assemble a UL 891-compliant electrical distribution switchboard by properly fabricating parts to mount Tmax-molded case circuit breakers (MCCBs). The program is designed for dead-front switchboards rated at 600 V or less and circuits having available rms symmetrical short-circuit currents no greater than 200 kA. It provides an extension of the company’s UL certification under which manufacturers may fabricate basic components using their own branding and includes extension procedures that facilitate the formal process for UL 891 compliance of chassis and enclosures.
