Product FAQs
6 answersWhat equipment is the THKR4610 circuit breaker designed to fit?
This 1000A K-Frame breaker is engineered for installation in GE switchboards, motor control centers, and A-Series panelboards. It shares the standard K1200 footprint for drop-in compatibility.
What type of wire lugs are required for this breaker?
The breaker requires standard GE K1200 frame lug kits. Depending on your wire size, you can use kits like the TCAL124, which accepts three 350 to 750 kcmil copper or aluminum conductors per phase.
What adjustability does the electronic trip unit provide?
The integrated electronic trip unit features adjustable long-time and instantaneous (LI) settings. This allows panel builders and electricians to fine-tune the protection curve for specific load requirements and system coordination.
Is the THKR4610 a suitable replacement for older GE K-Frame breakers?
Yes. Because it utilizes the legacy K1200 frame design, it serves as a direct physical replacement for older or failed 1000A K-Frame breakers in existing GE enclosures without requiring bus modifications.
Are internal accessories available for the THKR4610?
Yes, this breaker supports standard field-installable K-Frame accessories. You can integrate auxiliary switches, bell alarms, shunt trips, and undervoltage releases to meet specific control and safety requirements.
Does this breaker provide equipment ground fault protection?
No. The THKR4610 features an LI trip unit, which provides long-time and instantaneous protection only. If your application requires ground fault protection, you will need a breaker with an LSIG or LIG trip function.
