Shop Legrand DX3 MCB 3 Pole 16A Curve C Circuit Breaker | 409781 In Iraq Best Prices
Legrand DX³ three-pole 16A thermal-magnetic circuit breaker with 25kA breaking capacity, C curve protection, IP20 finger-safe design, and fully visible breaking mechanism for reliable circuit protection and isolation.
The Legrand DX³ is a three-pole modular thermal-magnetic circuit breaker designed for superior control, protection, and isolation of 16A circuits. With a breaking capacity of 25kA at 400V, this device delivers exceptional safety and reliability for residential and small commercial applications. The fully visible breaking mechanism ensures complete circuit isolation, while the C curve characteristic (tripping between 5In and 10In) provides optimal protection against short circuits ranging from 80A to 160A.
This IP20 finger-safe circuit breaker features fully visible breaking with DIN rail mounting for easy installation and removal. The device can be supplied by copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, offering flexible installation options. Compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, this MCB integrates seamlessly into modern electrical distribution systems.
The DX³ combines advanced thermal-magnetic protection technology with user-friendly design elements including ON/OFF indication printed on the handle with red and green backgrounds for easy status identification. Built with halogen-free materials and designed through an environmentally conscious process, this circuit breaker meets all substance-restriction requirements while delivering robust performance in demanding electrical environments.
