Legrand DX3 modular 2-pole thermal-magnetic circuit breaker with 80A D-curve rating, 10kA/16kA breaking capacity, IP20 finger-safe design, and DIN rail mounting for residential and small commercial electrical protection
The Legrand DX3 MCB 2 Pole 80A Curve D Circuit Breaker is a modular thermal-magnetic circuit breaker designed for comprehensive control, protection, and isolation of electrical circuits in residential and small commercial installations. This device features a D-curve release characteristic with 10kA breaking capacity according to IEC 60898-1 standard and 16kA breaking capacity according to IEC 60947-2, making it suitable for applications requiring moderate inrush current tolerance. The circuit breaker is equipped with IP20 finger-safe protection, red/green mechanical indicator for status display, and a label holder for convenient circuit identification.
The DX3 80A 2-pole breaker is constructed with a built-in depth of 47mm and operates at rated voltage of 400V with insulation voltage of 500V. It features screwed terminal connections compatible with multi-wired conductors of 6-50mm² and solid-core conductors of 6-70mm². The device can be supplied from the top or bottom and is mountable on DIN rail systems. With a tripping threshold between 800A and 1120A, this D-curve breaker provides reliable short-circuit protection while accommodating moderate load variations typical in residential and small commercial applications.
Designed with environmental consciousness, this halogen-free device complies with substance-restriction requirements and RoHS directives. The DX3 series is compatible with Legrand auxiliaries, RCD add-on modules, and various accessories, allowing for flexible system configuration. Operating across a frequency range of 50-60Hz and ambient temperatures from -25°C to 70°C, this circuit breaker delivers consistent performance and protection throughout its operational life. Installation should be performed by qualified electricians in compliance with local electrical codes and installation rules.
