Overview
The General Electric TFJ236200 is an industrial-grade molded case circuit breaker delivering reliable overcurrent protection for three-phase power distribution systems. This 200-amp, 600-volt 3-pole breaker combines thermal magnetic trip technology with non-interchangeable, adjustable trip settings to protect against both short circuits and sustained overloads. Part of GE’s F225 series, the TFJ236200 is suitable for feed-thru applications with line and load side lug terminals, making it ideal for panelboards, motor control centers, and switchgear installations.
Key Features
- Thermal magnetic protection — Long-time and instantaneous trip functions prevent nuisance trips while protecting against fault conditions
- Non-interchangeable trip unit — Adjustable magnetic trip set for precise coordination in complex power systems
- Bolt-on mounting — Quick installation in standard breaker enclosures and MCC sections
- Reverse feed capable — Designed to handle reverse-feed applications in paralleled generator or UPS scenarios
- Line & load side lugs — Pre-installed terminals for both incoming and outgoing connections
- High interrupting capacity — 22 kA at 480V, 18 kA at 600V AIC rating for demanding industrial environments

Replaces / Drop-In Replacement For
The TFJ236200 is a legacy General Electric F225 series product. As a discontinued model, direct replacements should be verified with your system integrator or GE distributor. Modern GE alternatives may include the SELA, SELJ, or SEHA series depending on your specific application requirements. For critical installations, consult with a qualified controls engineer before replacement.
Works With
- Industrial SCADA and automation control systems monitoring 600V distribution
- Remote trip and shunt coil accessories (24 VDC options available)
- Auxiliary contact assemblies for status indication
- Ground fault protection modules (when retrofitted)
- Standard industrial protective relay schemes per ANSI C37 standards
