General Electrics TKMA30800 - 800 A, 3-Pole Bolt-On Circuit Breaker | AmpState

Introducing the General Electrics TKMA30800 — an 800A, 3-pole bolt-on molded case circuit breaker engineered to protect large branch circuits with reliability in panelboards and loadcenters. Built for environments that demand steady performance, this unit pairs a rugged bolt-on mounting with precise thermal-magnetic protection to guard your electrical system against overcurrent and short-circuit events.

• 800A, 3-pole design — ideal for three-phase feeders and high-load circuits typical in commercial and light-industrial applications, providing coordinated protection across all phases.
• Bolt-on mounting — delivers a rigid, vibration-resistant bus connection that stays secure in panels subjected to equipment motion or ambient vibration.
• Thermal-magnetic trip unit — combines predictable thermal protection with fast magnetic response for effective fault interruption, helping to minimize damage and downtime.
• Molded case construction — compact, durable housing designed to withstand everyday industrial and service conditions while fitting seamlessly into compatible panelboards and loadcenters.
• OEM-compatible — engineered to be compatible with matching General Electrics OEM loadcenters and panelboards, ensuring straightforward replacement and reliable operation.
• Versatile applications — suitable for residential, commercial, and light industrial installations where substantial branch-circuit protection is required.

Why this 3-pole bolt-on breaker matters for your system

In three-phase electrical setups, balanced protection across all hot legs is crucial. The TKMA30800 provides synchronized disconnection across all three poles, helping prevent phase imbalances that can stress equipment and create unsafe fault conditions. The bolt-on mounting not only simplifies installation but also minimizes the risk of loose connections that can cause intermittent tripping or arcing over time.

Key features and practical benefits

• Stable protection performance through a thermal-magnetic trip that remains repeatable under varying load and temperature, reducing nuisance trips while preserving safety.
• Robust, panel-ready form factor designed to fit with General Electrics OEM loadcenters and panelboards, minimizing compatibility headaches during upgrades or replacements.
• Shielded against vibration with secure bolt-on mounting, making it a dependable choice for panels in mechanical rooms, workshops, or spaces with equipment vibration.
• Clear identification and traceability with exact part number TKMA30800, enabling precise ordering, stocking, and cross-referencing for maintenance schedules.

Ideal use cases and who benefits most

• Electrical contractors upgrading commercial space or light-industrial facilities that require robust 3-phase overcurrent protection.
• Facility managers looking to replace aging breakers in panelboards with matching OEM components to maintain system integrity.
• Residential builders or retrofits that demand higher-capacity protection for large loads or multi-zone services within panel centers.

Compatibility, installation tips, and considerations

Choose the TKMA30800 when your panelboard or loadcenter specification calls for a bolts-on, 3-pole, 800A thermal-magnetic molded case circuit breaker. Ensure proper torque on mounting screws to maintain the vibration resistance and bus integrity. This device is intended for branch circuit overcurrent and short-circuit protection, delivering dependable performance in both new builds and service panel refreshes.
