Shop Legrand MCB TX3 10000A 4 Pole 20A Curve C Circuit Breaker | 404257 In Iraq Best Prices
Thermal magnetic circuit-breaker with 10kA breaking capacity at 400V, C curve tripping, IP20 fingerproof safety, and 4-pole configuration for residential and commercial electrical installations.
The MCB TX3 10000A 4 Pole 20A Curve C is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a breaking capacity of 10kA at 400V and C curve characteristics, this device is suitable for controlling and isolating electrical installations. The circuit-breaker features IP20 fingerproof safety protection, meeting IEC 60898-1 standards for household installations. It can be supplied by copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), offering flexible installation options.
This advanced circuit-breaker incorporates maximum energy limitation (energy limitation class 3) to protect sensitive equipment and reduce electrical stress on the installation. The device is equipped with a special DIN rail clamp on the bottom side, allowing independent removal even when the fork busbar is still in place. It includes a label holder for clear circuit identification and ON/OFF indication printed on the handle with red and green backgrounds for easy status identification. The TX3 series can be equipped with Legrand DX3 auxiliaries and accessories, and can be connected to aluminum cable with appropriate terminal accessories.
The MCB TX3 complies with substance-restriction requirements and has been designed in an environmentally conscious process. Built with halogen-free materials, this circuit-breaker operates at a rated voltage of 400V with a rated insulation voltage of 500V. Its compact design with a built-in depth of 44mm and width of 70.8mm makes it ideal for space-constrained electrical panels. The device is manufactured in grey (RAL 7035) and includes comprehensive protection features including surge protection and pollution degree 2 rating.
