General Electrics SKLL36AT1200 - 1200 A, 3-Pole Bolt-On Circuit Breaker | AmpState

The General Electrics SKLL36AT1200 is a 1200A, 3-pole bolt-on molded case circuit breaker designed to safeguard panelboards and load centers from overcurrent and short circuits. Built for demanding electrical environments, this unit combines robust construction with precise protection, ensuring your high-current circuits stay secure and uninterrupted.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection that stays put in demanding installations.
• Thermal-magnetic trip unit delivers stable, repeatable protection by responding to both gradual overcurrents and instantaneous short-circuit events.
• 3-pole configuration supports three-phase protection, ideal for larger residential, commercial, and light industrial panel setups.
• 1200A amperage rating enables protection for high-load branch circuits, helping to prevent equipment damage and nuisance trips on demanding systems.
• OEM compatibility is designed to work with matching General Electrics load centers and panelboards, simplifying replacement and upgrades.
• Versatile applications suitable for residential, commercial, and light industrial environments where reliable circuit protection is critical.

In practice, this breaker acts as a dependable safeguard for critical feeders and distribution paths. The thermal element anticipates heat buildup in normal operation, while the magnetic mechanism provides a fast response to short circuits, helping to minimize damage to wiring, devices, and downstream equipment. The result is predictable protection performance that electricians can trust during routine maintenance or after system expansions.

Key considerations for installation and use

• Ensure the panelboard or loadcenter is designed for bolt-on, 3-pole molded case breakers and can accommodate a 1200A rating.
• Follow manufacturer torque specifications and mounting guidelines to preserve the integrity of the bus connection and trip operation.
• When upgrading or replacing, prioritize units that offer OEM compatibility to maintain consistent protection coordination and mechanical fit.

For professionals building or updating high-current electrical distributions, the SKLL36AT1200 combines a rugged bolt-on design with precise thermal-magnetic protection, delivering reliable performance in a compact, OEM-compatible package. This is the choice for serious branch circuit protection where consistency and durability matter most.
