Legrand DX3 2-pole 3A thermal magnetic circuit breaker with 16kA breaking capacity at 230V, Type C curve, IP20 protection, and advanced energy limitation for reliable protection of residential and small commercial electrical installations.
The Legrand DX3 MCB 2P 3A is a thermal magnetic circuit breaker designed to protect residential and small commercial wiring installations against overloads and short-circuits. With a breaking capacity of 16kA at 230V and 10kA at 400V, this device provides reliable protection with C curve tripping characteristics. The 2-pole, 3A rating makes it ideal for controlling and protecting low-current installations in homes and small commercial buildings. Featuring advanced energy limitation technology (Class 3) according to IEC 60898-1 standards, this MCB minimizes let-through energy during fault conditions, ensuring enhanced safety and equipment protection.
This circuit breaker can be supplied via multiple connection methods including copper cables, prong busbars (top or bottom side), fork busbars (bottom side), or Legrand HX3 plug busbars (top side). The device is protected against solid bodies larger than 12.5mm with IP20 rating according to IEC/EN 60529 standards. It features independent DIN rail clamps on both top and bottom sides, allowing removal without disturbing the main busbar supply. The label holder provides clear circuit identification, while ON/OFF indications printed on the handle with red and green backgrounds enable easy status monitoring.
The DX3 MCB is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories for enhanced functionality. Its halogen-free construction demonstrates environmental responsibility, and it complies with all substance-restriction requirements. Built with robust design principles and engineered for durability, this circuit breaker is suitable for flush-mounted installation in standard distribution panels and complies with all relevant international safety standards for household and small commercial electrical installations.
