Legrand DX3 thermal magnetic circuit-breaker with 25A rating, D-curve tripping, 25kA breaking capacity, IP20 protection, and mechanical status indicator for reliable circuit protection and isolation
The Legrand DX3 MCB 1 Pole 25A Curve D is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This advanced protective device offers a breaking capacity of 25kA at 230V, making it ideal for residential and small commercial applications. The D-curve tripping characteristic provides excellent protection with a tripping threshold between 250A and 350A (10-14 times the rated current), ensuring reliable circuit control and isolation. The device features IP20 protection rating, safeguarding against solid bodies larger than 12.5mm, and is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories for enhanced functionality.
This circuit-breaker is equipped with a red/green mechanical indicator that clearly displays the status of the contacts (open or closed), and includes a convenient label holder for circuit identification. The 1.5 modular spacing design allows for compact installation in distribution panels. Built-in depth of 47mm and overall dimensions of 26.7mm width x 127.5mm height x 79.2mm depth make it suitable for flush-mounted installations. The device operates across AC voltage at rated voltage of 230V with rated insulation voltage of 500V and impulse withstand voltage of 6kV, functioning reliably at frequencies of 50-60Hz.
The MCB can be supplied by copper cable from either top or bottom side connection points, accommodating multi-wired conductor cross-sections from 1.5-35mm² and solid-core conductors from 1.5-50mm². With an ambient operating temperature range of -25 to 70°C and storage temperature capability from -40 to 70°C, this circuit-breaker maintains consistent performance across varied environmental conditions. The product complies with substance-restriction requirements and has been designed following environmentally conscious processes. Reference number 409809 with EAN 3245064098090 ensures proper identification and traceability.
