Technical Specifications:

1. Rated Current (In): 1600A, designed for heavy electrical loads.
2. Voltage Rating: Suited for medium and low-voltage applications, typical in industrial power distribution.
3. Poles: Three-pole (3p) configuration, offering balanced protection across phases in three-phase systems.
4. Overcurrent Protection: PR121/P-LSIG release unit offers comprehensive overcurrent protection modes:
   • L (Long-Time) for overload protection.
   • S (Short-Time) to clear faults faster.
   • I (Instantaneous) to handle high-magnitude short circuits.
   • G (Ground Fault) protection, reducing risks associated with ground faults.
5. Integrated Auxiliary Contacts: Equipped with 4 auxiliary contacts for enhanced communication and monitoring capabilities, allowing external systems or panels to receive circuit breaker status (open/closed) signals.

Additional Features:

• Self-Diagnostics and Alarm Functions: PR121/P-LSIG features diagnostic capabilities to monitor internal parameters, assisting with predictive maintenance.
• Selectable Trip Curves: Adjustable settings within the PR121/P-LSIG allow for customized trip curves, enhancing adaptability to specific load conditions.
• Reliability and Durability: Engineered for industrial-grade environments, the E1N model includes robust housing and high-quality components for long-term use under stress.
