Single-Pole and Neutral (1P+N) Protection:
Designed for single-phase circuits, the ADC920T provides protection for both the live and neutral conductors, ensuring complete disconnection in the event of a fault.
6 kA Short-Circuit Breaking Capacity:
Capable of interrupting fault currents up to 6,000A, safeguarding circuits and connected devices from damage due to short circuits.
C-Curve Tripping Characteristic:
Offers delayed tripping for moderate inrush currents, making it suitable for circuits that include equipment with high startup currents, such as motors or lighting systems. The C-curve ensures that these devices don’t trip during normal operation.
Wide Operating Temperature Range:
Operates efficiently in temperatures ranging from -25°C to +70°C, making it versatile for a variety of industrial and commercial environments.
Secure Screw Terminal Connections:
Equipped with screw terminals for a secure electrical connection, the ADC920T ensures low resistance and minimal risk of loose or faulty connections.
FEATURES:
Comprehensive Overcurrent Protection:
Protects against both overload and short-circuit conditions, ensuring the protection of both the electrical wiring and the connected devices, which helps avoid potential damage and fires.
Long Lifespan:
Rated for 10,000 electrical operations and 20,000 mechanical cycles, making it durable enough for frequent switching in commercial or industrial applications where long-term performance is essential.
Certified and Compliant:
Complies with IEC 60898-1 and IEC 60947-2 standards, ensuring it meets international safety requirements. The RoHS certification also ensures that it is environmentally friendly.
