EKM1-63 AC circuit breaker provides reliable protection for photovoltaic system AC circuits with a 6kA breaking capacity, specifically engineered to address the unique protection requirements of solar power installations. Available in multiple configurations, this breaker offers essential overcurrent and short-circuit protection to safeguard your inverters, AC distribution systems, and grid interconnection points.
Applications
• Grid-Tied Residential Systems: Protects against AC-side faults in single-phase 240V systems with ≤10kW inverters
• Solar Water Pumping Systems: Handles motor starting currents (D-curve) in off-grid agricultural applications
• Battery Backup Systems: Provides overload protection for ≤20kVA hybrid inverters
• DC-AC Combiner Boxes: Branch circuit protection for parallel inverter configurations
