Shop Legrand DX3 MCB 1 Pole 25A B-Curve 6000A Circuit Breaker | 407434 In Iraq Best Prices
Single-pole thermal magnetic circuit breaker with 25A rating, B-curve characteristic, and 6000A breaking capacity. Provides IP20 finger-safe protection with energy limitation class 3 for reliable overcurrent and short-circuit protection in residential and small commercial installations.
The Legrand DX3 MCB (Miniature Circuit Breaker) is a thermal magnetic circuit-breaker specifically designed to protect wiring installations against overloads and short-circuits. With a rated current of 25A and B-curve tripping characteristic, this device provides reliable protection for residential and small commercial applications. The 6000A breaking capacity according to IEC 60898-1 standard ensures safe disconnection during fault conditions, with tripping threshold between 75A and 125A for short-circuit protection.
This single-pole circuit breaker features IP20 finger-safe protection, meeting IEC/EN 60529 standards, making it safe for use in standard electrical installations. The device incorporates high energy limitation class 3 according to IEC 60898-1 standard, minimizing let-through energy during fault conditions. It can be supplied by copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side), offering flexible installation options.
The MCB DX3 is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, allowing for customized installation configurations. Built with halogen-free materials and designed through an environmentally conscious process, this device complies with substance-restriction requirements including RoHS Directive and REACH Declaration. The compact design with 1-module width (17.8mm) fits standard DIN rail installations, featuring independent removal capability through dual DIN rail clamps.
