Key specifications

• Part number: SK12SPK
• Current rating: 1200 A
• Poles: 3
• Voltage rating: 600 V

What this means for your electrical protection

Three-phase loads power larger equipment and motors. This 3-pole circuit breaker provides balanced protection across all three phases, helping to prevent uneven faults that can stress wiring and downstream devices. The 600 V rating aligns with common industrial power distribution schemes, while the 1200 A rating supports sizable feeders and service conductors, reducing the risk of nuisance trips while still safeguarding against faults.

Ideal use cases

• Main service disconnects for medium-to-large commercial and industrial facilities
• Protection for three-phase motor circuits and feeders in manufacturing lines
• Replacement or upgrade component within GE SK-series panelboards
• Panel protection in environments like data centers, HVAC plants, and processing rooms

Installation & compatibility notes

Confirm that you’re installing within a GE SK-series-compatible panel or system. Check your panel labeling and busbar arrangement to ensure proper three-pole protection. For safety and reliability, install by a qualified electrician and adhere to local electrical codes and standards.
