General Electrics TKMA836350 - 350 A, 3-Pole Bolt-On Circuit Breaker | AmpState

The General Electrics TKMA836350 is a robust 350A, 3-pole bolt-on molded case circuit breaker designed to deliver reliable branch circuit protection in panelboards and load centers. Built for demanding environments, this unit combines a secure bolt-on mounting with a precise thermal-magnetic trip system to keep electrical systems safe and operating smoothly.

• Bolt-on mounting provides a rigid, vibration‑resistant bus connection, helping maintain a solid electrical connection in busy electrical rooms and equipment spaces.
• Thermal-magnetic trip unit delivers stable, repeatable protection against overcurrent and short-circuit events, reducing nuisance trips while guarding residential, commercial, and light industrial circuits.
• 350A, 3-pole design offers substantial current capacity for large branch circuits and multi‑wire distribution, making it suitable for panelboards and load centers that require dependable high‑amp protection.
• OEM compatibility is maintained with matching load centers and panelboards, simplifying upgrades and replacements in systems that rely on original equipment specifications.
• Versatile applications across residential, commercial, and light industrial settings, especially where secure mounting and robust protection are priorities.

Why this matters: In environments with vibration, multiple feeders, or frequent cycling, a bolt-on MCCB like the TKMA836350 minimizes connection looseness and ensures consistent trip performance. The combination of a heavy-duty mounting method and a dual-mode trip mechanism means you get rapid response to short circuits and dependable overload protection, protecting wiring, devices, and downstream equipment.
