Shop Legrand DX3 MCB 1 Pole 16A Curve B Circuit Breaker | 407432 In Iraq Best Prices
Single-pole thermal magnetic circuit-breaker with 16A rated current, 6kA breaking capacity, B-curve tripping, and advanced protection features for residential and small commercial installations
The Legrand DX3 MCB 6000A is a thermal magnetic circuit-breaker specifically designed to protect wiring installations against overloads and short-circuits with a 6kA/10kA breaking capacity and B-curve tripping characteristic. This single-pole device features advanced energy limitation (Class 3) and can be supplied via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar. The circuit-breaker incorporates fingerproof protection (IP20) and is compatible with DX³ auxiliaries, RCD add-on modules, and various accessories, making it ideal for residential and small commercial panel installations.
This device combines reliable protection with user-friendly design features including a labeled handle with ON/OFF indication printed on red and green backgrounds for easy circuit identification. The MCB is equipped with two DIN rail clamps allowing independent removal even when the prong busbar is energized. It accepts connections from both solid-core and multi-wired conductors with cross-sections ranging from 1.5 to 35mm², providing flexibility for various installation requirements.
Designed with environmental consciousness, this product complies with substance-restriction requirements and RoHS directives. The thermal magnetic tripping mechanism activates between 48A and 80A (B-curve between 3In and 5In), providing optimal protection for standard household and light commercial applications. Installation should be performed by qualified electricians in compliance with local electrical installation codes.
