Three-Pole Protection (3P):
Ideal for three-phase circuits, providing simultaneous disconnection of all phases for enhanced safety.
6 kA Short-Circuit Breaking Capacity:
Ensures safe interruption of fault currents up to 6,000A, offering reliable protection in commercial and industrial settings.
C-Curve Tripping Characteristic:
Handles moderate inrush currents, such as those from motors or fluorescent lighting, preventing nuisance tripping.
DIN Rail Mountable – 3 Module Width:
Designed for quick installation on standard DIN rails; occupies 3 modules in width, saving space in distribution boards.
FEATURES:
Wide Temperature Tolerance:
Operates between -25°C and +70°C, suitable for varied environments.
Secure Screw Terminals:
Provides firm and stable wiring connections, reducing risk of arcing or loose connections.
Dual Overcurrent Protection:
Offers protection from both overloads and short circuits, ensuring electrical safety for connected equipment.
High Operational Endurance:
Supports up to 4,000 electrical and 20,000 mechanical operations for long-term reliability.
Complies with IEC Standards:
Built to IEC 60898-1 standards and RoHS compliant, ensuring global conformity and eco-friendly design.
Compact and Modular:
Fits seamlessly into standard consumer units or commercial panels without the need for special adapters.
