GE TJK636350 - 350 A, 600 V, 3-Pole Circuit Breaker | AmpState

GE TJK636350 – 350A, 600V, 3-Pole Molded Case Circuit Breaker guards power for panelboards and load centers by delivering precise branch circuit overcurrent and short-circuit protection. Built for reliability in commercial, residential, and light industrial environments, this GE MCCB combines a compact form with a robust thermal-magnetic trip system to keep your distribution network safe and responsive.

• Compact molded case design maximizes panel space and simplifies installation, helping you fit more protective devices into tighter electrical enclosures.
• Thermal-magnetic trip unit delivers stable, repeatable protection across varying loads and temperatures, with a thermal element handling gradual overloads and a magnetic element delivering an instantaneous response to short circuits.
• 3-pole configuration provides balanced three-phase protection and streamlined wiring for modern distribution panels.
• OEM compatibility designed to pair with matching GE OEM load centers and panelboards for consistent fit, clearance, and trip characteristics.
• High-current, high-voltage performance rated at 350A and 600V, suitable for mid-to-large loads in commercial or light industrial applications.
