High-performance four-pole modular circuit breaker with 25kA breaking capacity, D-curve protection, and IP20 rating for reliable electrical circuit protection
The MCB DX3 Four Pole 6A Curve D is a modular thermal-magnetic circuit breaker designed for reliable protection and isolation of electrical circuits in residential and small commercial installations. This advanced protective device delivers an impressive 25kA breaking capacity at 400V AC, making it ideal for demanding electrical environments. With its D-curve protection characteristic, it provides optimal tripping thresholds between 60A and 84A for short-circuit conditions, ensuring superior circuit protection against overloads and faults.
This circuit breaker features a fully visible breaking mechanism that allows users to clearly see the operational status of the device. The IP20 protection rating ensures the device is protected against solid bodies larger than 12.5mm, making it fingerproof and safe for installation in various environments. The breaker can be supplied through multiple connection methods including copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, providing flexibility in installation configurations.
The DX3 is engineered with DIN rail mounting capability, featuring two independent clamps on the top and bottom sides for easy installation and removal even when the busbar is energized. It is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, allowing for customization and expansion of protection systems. The device complies with all substance-restriction requirements and has been designed with environmental consciousness in mind, featuring halogen-free construction.
