Delivering massive 800-amp capacity, this integrally fused three-pole breaker achieves a 200kAIC interrupt rating at 480VAC. The TB83800 is engineered for robust industrial power distribution, mounting securely into GE AV-Line switchboards and motor control centers. While this specific Tri-Break frame has been succeeded by the ABB Tmax XT series for new installations, it remains a critical exact-fit replacement component for maintaining existing high-fault commercial electrical infrastructure.
