Single-Pole and Neutral (1P+N) Protection:
Provides complete protection for single-phase circuits, disconnecting both the live and neutral conductors in case of a fault. This ensures full protection against residual current faults.
6 kA Short-Circuit Breaking Capacity:
The ADC925T can safely interrupt fault currents up to 6,000A (6kA), offering enhanced protection against short-circuit events that could damage electrical systems and connected equipment.
C-Curve Tripping Characteristic:
Equipped with a C-curve characteristic, the RCBO ensures delayed tripping for circuits with equipment that might experience temporary inrush currents (e.g., motors and transformers). This helps prevent false tripping during start-up.
Wide Operating Temperature Range:
It operates in a temperature range of -25°C to +70°C, making it versatile for a variety of environments, from residential to industrial settings, even under extreme conditions.
Secure Screw Terminal Connections:
Comes with screw terminals for secure and reliable connections, reducing the risk of poor contact and ensuring low-resistance connections for long-term safety.
Overcurrent and Residual Current Protection:
Protects against both overload and short-circuit conditions, while also detecting residual (earth leakage) currents, ensuring complete safety against electrical faults. This protection is vital for preventing electrical fires and equipment damage.
FEATURES:
Long Mechanical and Electrical Life:
The ADC925T is rated for 10,000 electrical operations and 20,000 mechanical cycles, making it a durable choice for high-demand applications with frequent switching.
Compliant with International Standards:
The ADC925T complies with IEC 61009-1 and AS/NZS 61009-1 standards, ensuring that it meets rigorous international safety requirements. It is also RoHS compliant, meaning it is free from hazardous substances.
