Product FAQs
8 answersWhat types of electrical equipment are compatible with the TFK236225 circuit breaker?
The TFK236225 is a legacy F-frame breaker engineered specifically for bolt-on integration into GE A-Series panelboards, Spectra Series switchboards, and GE motor control centers. It is commonly used to maintain or expand existing General Electric distribution systems.
What are the wire size and torque specifications for the lugs on the TFK236225?
The standard lugs accept 4 AWG to 300 kcmil copper or aluminum conductors. When using the compatible TCAL26 aluminum terminal lug kit, the recommended tightening torque is 275 lb-in. Always verify torque requirements on the physical breaker label before terminating.
Is the GE TFK236225 still in active production, or is there a modern replacement?
The TFK frame is a legacy General Electric design. For facilities looking to modernize their switchgear, ABB offers the Tmax XT4 series as a direct upgrade path, which can be installed using a dedicated retrofit kit.
How does the trip unit function on the TFK236225?
This breaker utilizes a thermal magnetic trip unit with a fixed thermal element for the 225A continuous rating and an adjustable magnetic element. The adjustable instantaneous trip allows electricians to coordinate the breaker with downstream loads or account for motor inrush currents.
Does the TFK236225 provide ground fault or equipment protection?
No, this model provides standard long-time and instantaneous (LI) overcurrent and short-circuit protection. It does not feature integral ground fault sensing (GFPE) or arc fault protection.
Can the TFK236225 be utilized in direct current (DC) systems?
Yes, in addition to its AC ratings, this breaker is rated for 250VDC with a 10kA interrupting capacity. This makes it suitable for specific industrial DC applications, provided the system voltage does not exceed 250V.
Is the TFK236225 suitable for HVAC applications?
Yes, this breaker is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment that requires a 225A overcurrent protection device.
Does the TFK236225 feature an interchangeable trip unit?
Yes, this breaker is designed with an interchangeable trip unit. This allows panel builders to swap the trip mechanism without replacing the entire breaker frame if load requirements change in the future.
