General Electric SKLL36BA1200 1200A 3-Pole 600 V Circuit Breaker

General Electric SKLL36BA1200 is an industrial-grade circuit breaker designed to protect multi-phase electrical systems under heavy load. With a 1200 A current rating and a robust 3-pole configuration, this 600 V breaker is built to shield feeders and downstream equipment in demanding commercial and industrial environments.

Key specifications at a glance

• Current rating: 1200 A
• Poles: 3
• Voltage rating: 600 V
• Part number: SKLL36BA1200

Why this GE circuit breaker stands out

• Three-pole design provides synchronized protection across all phases, preventing uneven loading and phase imbalance in three-phase power systems.
• Engineered for heavy-duty service in panelboards and switchgear, helping to isolate faults quickly and protect expensive equipment such as motors, drives, and large pumps.
• Designed to integrate with GE distribution equipment, offering reliable compatibility and serviceability within established electrical infrastructure.

Ideal use cases

• Main feeder protection in large commercial buildings, industrial facilities, or data centers where a 1200 A line is required.
• Three-phase protection for large motors, compressors, conveyors, and processing equipment.
• Backup protection in multi-panel layouts where a single, high-current breaker consolidates protection for multiple circuits.

Practical tips for installation and care

• Verify panel compatibility with SKLL36BA1200 and ensure mounting and interconnection follow GE guidelines for high-current devices.
• Consider coordinated protection with upstream overcurrent devices to optimize selectivity and minimize unnecessary outages.
• Handle with proper PPE and de-energize equipment when installing or replacing the breaker to maintain safety and compliance.
