Single-pole thermal magnetic circuit breaker with 63A rated current, D-curve protection, 10/16kA breaking capacity, IP20 protection, and DIN rail mounting for residential and commercial electrical installations
The Legrand MCB DX3 10000A is a thermal magnetic circuit breaker designed to protect wiring installations against overloads and short circuits. This single-pole device features a 63A rated current with D-curve release characteristic, providing reliable protection at 230/400V~ rating. With a breaking capacity of 10/16kA, this circuit breaker ensures robust fault clearance and allows convenient control and isolation of electrical circuits. The device complies with IEC 60898-1 standard for household installations and features a tripping threshold between 630A and 882A for short-circuit protection.
This MCB is equipped with advanced safety features including IP20 protection against solid bodies larger than 12.5mm (fingerproof protection) as per IEC/EN 60529 standard. The breaker can be supplied via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar connections. It features two DIN rail clamps allowing independent removal while the power supply remains active. The grey-colored device (RAL 7035) measures 17.8mm width and fits standard DIN rail installations with 1 modular spacing.
The product includes convenient features such as on/off indication printed on the handle with red and green backgrounds for easy status identification, and a label holder for clear circuit identification. It can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories. The device is halogen-free and designed with environmental consciousness, complying with substance-restriction requirements. Operating temperature range is -25 to 70°C, with storage capability from -40 to 70°C.
