The PKZ-SOL string circuit breaker from Eaton’s Moeller series™ provides a fuseless alternative for protection against short-circuit currents. To ensure maximum protection, each PKZ-SOL device is installed inside a customer-specific junction box. An auxiliary contact provides information on the switching status, while the documentation contains a diagram that explains the exact relationship between the tripping current of the protective device and the short-circuit current of the PV

• Rated operational voltage: 900 V DC
• Permissible short-circuit currents Isc in the string: from 1.6 A to 22 A
• Rated currents of 12 A, 20 A and 30 A

• Remote disconnect: undervoltage releases
• Customer-specific: adjustable trip settings
