Thermal magnetic 2-pole 4A circuit-breaker with C-curve characteristic, 16kA breaking capacity at 230V, IP20 protection, and energy limitation class 3 for residential and small commercial installations
The Legrand DX3 MCB 2P 4A Curve C is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a 2-pole configuration and 4A rated current, this device features a C-curve release characteristic with 16kA breaking capacity at 230V and 10kA at 400V. It provides IP20 finger-safe protection and energy limitation class 3, making it suitable for residential and small commercial applications. The breaker is equipped with two DIN rail clamps for independent removal and includes a label holder for clear circuit identification.
This circuit-breaker can be supplied through multiple connection methods including copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar. It complies with IEC 60898-1 standard for household installations with a tripping threshold between 20A and 40A (C curve between 5 In and 10 In). The device is halogen-free and designed with environmental consciousness. It can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and accessories for enhanced functionality.
With a built-in depth of 44mm and width of 35.4mm (2 modular spacings), this compact breaker fits standard DIN rail installations. The device operates in ambient temperatures from -25°C to 70°C and features a grey color (RAL 7035). It supports connectable conductor cross sections from 1.5-25mm² for multi-wired and 1.5-35mm² for solid-core conductors, with screwed terminal connections for secure installation.
