General Electric | TB43200 | Circuit Breaker | 3-Pole

General Electric TB43200 3-Pole Circuit Breaker is a purpose-built protective device for three-phase electrical systems. Engineered for maintenance, retrofit, and replacement, it ensures reliable interruption across all three phases in GE-compatible panels.

• Three-pole configuration: Designed to protect three-phase circuits by switching all three conductors together, promoting balanced protection and reducing the risk of phase-related faults that can harm motors and other equipment.
• Exact compatibility reference: The TB43200 part number is your best guide for matching panels and breakers. Use this reference to confirm the breaker fits the GE system you’re working on.
• Maintenance, retrofit, and replacement: Ideal for refreshing aging protection in service panels, upgrading or restoring three-phase protection where GE components are specified.
• Fit and ratings verification: Before ordering, verify that the breaker's electrical ratings (voltage, current, and trip characteristics) align with your panel’s documented requirements and labeling.

Who should consider the TB43200?

• Technicians and facilities managers performing panel maintenance or retrofits in GE-listed installations that require a 3-pole circuit breaker.
• Owners updating old equipment to maintain reliable three-phase protection without changing the entire panel lineup.
• Projects where a matching GE component order is prioritized to preserve system performance and warranty alignment.

How to verify compatibility

• Check your panel’s documentation or labeling to confirm that TB43200 is the required breaker type.
• Ensure the panel’s voltage and current requirements match the TB43200’s specifications and the panel’s trip characteristics.
• Confirm the physical form factor and mounting method align with your GE panel design to ensure a proper, secure fit.

Practical guidance for safer, smoother installation: always work with the power off, follow electrical codes, and consult a licensed electrician if you’re uncertain about ratings or compatibility. The TB43200 is a reliable, GE-aligned choice for maintaining robust three-phase protection where your system relies on a precise, part-number-specific breaker.
