-
Application Scenarios: Main breaker for large industrial switchboards, 600 V AC three‑phase distribution, data‑center power infrastructure, and other heavy‑commercial/industrial installations requiring 1200 A protection.
-
Structural & Material Characteristics: Molded‑case housing; bolt‑on stab connections; microEntelliGuard solid‑state trip unit; interchangeable trip module; lug terminals for large‑gauge conductors.
-
Installation Requirements: Bolt‑on mounting in GE Spectra SK‑compatible switchboards or enclosures; use proper torque for bolt‑on stabs; connect conductors sized for 1200 A service; ensure the panel’s available fault current does not exceed 65 kA at 480 V; de‑energize before installation.
-
Usage Precautions: Installation and service must be performed by licensed electricians; follow LOTO; verify AIC rating (65 kA) matches system fault levels; do not exceed 600 V AC or 1200 A; calibrate the solid‑state trip unit per load requirements; inspect lug torque periodically.
