Premium 3-pole 63A modular circuit breaker with 50kA breaking capacity, C-curve protection, IP20 finger-safe terminals, and DIN rail mounting for residential and commercial electrical installations.
The Legrand DX3 3 Pole 63A Curve C is a premium modular thermal-magnetic circuit breaker designed for comprehensive control, protection, and isolation of electrical circuits in residential and small commercial applications. This advanced device delivers an impressive 50kA breaking capacity at 400V and features a C-curve tripping characteristic that provides optimal protection with a tripping threshold between 315A and 630A (5-10 times the rated current). The circuit breaker is engineered with IP20 finger-safe terminals, ensuring maximum safety during installation and maintenance operations.
With a built-in depth of just 47mm and a width of 4.5 modular spacings, this compact device integrates seamlessly into standard DIN rail-mounted distribution panels. The DX3 series incorporates a red/green mechanical indicator that clearly displays the contact status (open or closed), and features a convenient label holder for circuit identification. The device supports both top and bottom copper cable supply connections, offering flexibility in installation configurations. It operates reliably across a frequency range of 50-60Hz and maintains performance in ambient temperatures from -25°C to +70°C.
The DX3 3 Pole 63A Curve C is fully compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, making it an ideal choice for modular electrical installations. Built with halogen-free materials and designed through environmentally conscious manufacturing processes, this circuit breaker complies with RoHS directives and substance-restriction requirements. Its robust construction with IK02 impact resistance ensures durability in demanding installation environments.
