Thermal magnetic 4-pole circuit breaker with 16A rating, C-curve protection, 6kA breaking capacity, IP20 safety, and full DX3 compatibility for reliable electrical system protection.
The Legrand DX3 MCB 6000A is a thermal magnetic circuit-breaker specifically designed to protect wiring installations against overloads and short-circuits. This 4-pole device operates at 16A with a 400V AC rating and features a C-curve tripping characteristic, making it ideal for residential and small commercial applications. With a 6kA/10kA breaking capacity, it provides reliable protection for electrical systems while maintaining IP20 finger-safe protection standards.
This circuit breaker is engineered with advanced current limiting technology (class 3 energy limitation) to minimize let-through energy during fault conditions. The device can be supplied via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar connections, offering flexible installation options. It features DIN rail mounting with independent removal capability, allowing maintenance without disrupting the entire installation.
The MCB DX3 is fully compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, making it a versatile solution for electrical distribution systems. Built with environmentally conscious design principles and halogen-free materials, it complies with all substance-restriction requirements and relevant international standards including IEC 60898-1 and IEC 60947-2.
