Three-Phase Protection (3P):
Provides reliable protection for three-phase circuits, ensuring that all three phases are disconnected simultaneously in the event of an overcurrent or fault. Ideal for industrial or commercial applications.
6 kA Short-Circuit Breaking Capacity:
Can safely interrupt fault currents up to 6,000A, protecting the circuit from damage due to short circuits and ensuring operational safety.
C-Curve Tripping Characteristic:
Handles moderate inrush currents, making it suitable for circuits that involve lighting, motors, and other equipment with normal startup currents. The C-curve provides delayed tripping to handle these loads effectively.
Compact Design – 3 Modules Wide:
Mounts easily onto a DIN rail, occupying just three modules of space, allowing for efficient use of space in electrical panels.
Wide Operating Temperature Range:
Operates reliably between -25°C and +60°C, suitable for various environmental conditions in both industrial and commercial settings.
Secure Screw Terminal Connections:
Provides strong and reliable electrical connections, minimizing the risk of loose or poor connections. This ensures the safety and stability of the circuit.
FEATURES:
Comprehensive Overcurrent Protection:
Protects the circuit from both overload and short-circuit conditions, providing comprehensive protection for the circuit and preventing equipment damage.
Long Lifespan:
Rated for 4,000 electrical operations and 20,000 mechanical cycles, making it ideal for use in applications where frequent switching occurs. It’s built to last.
Certified and Compliant:
Complies with IEC 60898-1 and is RoHS compliant, ensuring both safety standards and environmental responsibility in the manufacturing process.
