This K-frame breaker is engineered for use in legacy General Electric switchboards, motor control centers, and Type CCB panelboards.
What are the lug wire capacity limits for this 800A breaker?
The standard terminal lugs accommodate up to three conductors per phase. They accept aluminum or copper wire sizes ranging from 3/0 AWG to 500 kcmil.
What adjustability does the thermal-magnetic trip unit offer?
The trip unit provides fixed thermal protection for long-time overloads and features an adjustable magnetic dial to set the instantaneous short-circuit pickup level.
Is the TKM826800 rated for use in DC circuits?
Yes, this breaker supports direct current applications up to 250VDC with an interrupting capacity of 20kA.
Does this breaker require a specific mounting configuration?
It requires a bolt-on connection, meaning it must be mechanically fastened directly to the panelboard or switchboard bus using bolted hardware rather than plugging in.
