GE TR8B400 - 400A, Circuit Breaker

Meet the GE TR8B400 — a purpose-built 400A circuit breaker designed for demanding electrical systems. This GE component delivers dependable overcurrent protection in panelboards, switchboards, control panels, and OEM equipment, making it a trusted cornerstone for industrial, commercial, and OEM applications where safety and reliability matter.

• Current rating: 400A
• Breaker type: Circuit Breaker

Why this matters in real-world setups

• In distribution panels and motor control centers, reliable overcurrent protection is essential to guard feeders, motors, and downstream devices from overloads and faults. The TR8B400 is engineered to meet that need with sturdy performance in tough environments.
• For OEM equipment and integrators, having a breaker that fits GE panel and control architectures reduces compatibility risk and speeds up installation or retrofits.
• Industrial and commercial facilities benefit from a proven protection solution that supports safe operation, downtime minimization, and straightforward maintenance planning.

Ideal use cases

• New construction or retrofits in manufacturing plants, warehouses, and data centers where 400A protection is required.
• Protection of main feeders and critical loads in distribution panels and motor control centers.
• OEM assemblies that demand reliable, high-current protection within GE-compatible systems.

What sets it apart

• Specifically designed for 400A protection in heavy-duty electrical distribution, enabling streamlined panel design and fewer components.
• Aligned with GE’s electrical infrastructure, offering seamless compatibility and easier replacements or upgrades.
• Built for safe operation in demanding environments, contributing to reduced downtime and enhanced system reliability.

Practical guidance for installation and selection

• Verify panelboard or switchboard compatibility with the TR8B400 to ensure correct fit and termination procedures.
• Align downstream equipment ratings and motor control center configurations with the 400A protection level to maximize protection coverage.
• Consult GE installation guidelines for wiring practices and installation torque to maintain long-term performance and safety.

Equip your electrical distribution with the GE TR8B400 and experience robust, dependable protection that supports smooth operation across industrial, commercial, and OEM environments.
