GE TJK636Y600 - 600 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Discover the GE TJK636Y600—a robust 3-pole, bolt-on molded case circuit breaker engineered for dependable branch-circuit protection in panelboards and loadcenters. With a 600A rating at 600V, this breaker is designed to handle demanding three-phase distribution while staying compact enough for practical installations.

Why this breaker stands out

• Secure bolt-on mounting for a rigid, vibration-resistant bus connection: minimizes movement and lug loosening in environments with vibration or heavy equipment, delivering consistent electrical contact over time.
• Thermal-magnetic trip unit for stable protection: combines thermal overload sensing with magnetic short-circuit tripping, providing fast, repeatable responses across a range of temperatures and load conditions.
• OEM-compatible design: built to integrate seamlessly with matching GE OEM loadcenters and panelboards, making replacements or upgrades straightforward without rewiring.
• Three-pole, 600A, 600V configuration: ideal for three-phase distribution in residential-adjacent, commercial, and light industrial applications where large branch circuits need reliable protection.
