Product FAQs
5 answersWhich panelboards are compatible with the TE122045 circuit breaker?
The TE122045 is designed specifically for use in General Electric A-Series panelboards. It features a bolt-on connection to ensure a secure fit within these commercial and industrial panels.
Is there a direct replacement for the legacy GE TE122045 breaker?
Yes, the original TE frame has been superseded by the TEB frame. The GE TEB122045 is the direct, modern replacement and will fit into the same A-Series panelboard spaces as the older TE122045.
What wire sizes and materials are accepted by the lugs on the TE122045?
The terminal lugs on this breaker accept copper (Cu) wire from 14 AWG to 3 AWG, and aluminum (Al) wire from 12 AWG to 1 AWG. Ensure proper torque specifications are followed during installation.
Can the GE TE122045 be used in direct current applications?
Yes, in addition to its standard 120/240VAC and 240VAC ratings, this thermal-magnetic breaker is rated for use in DC systems up to 250VDC with a 5kA interrupting capacity.
How does the thermal-magnetic trip unit function on the TE122045?
The breaker utilizes a fixed trip unit with long-time and instantaneous (LI) functions. The thermal element provides delayed tripping for sustained overloads, while the magnetic element trips instantaneously to protect against short circuits.
