Shop Legrand TX3 MCB 2 Pole 16A Circuit Breaker C Curve | 403528 In Iraq Best Prices
Legrand TX3 2-pole thermal-magnetic circuit breaker with 16A rated current and 6000A breaking capacity. Features C-curve tripping characteristic, IP20 protection, and DIN rail mounting for reliable household electrical protection.
The Legrand TX3 MCB 403528 is a high-performance thermal-magnetic circuit breaker designed to protect residential and small commercial wiring installations against overloads and short circuits. With a breaking capacity of 6000A according to IEC 60898-1 standard, this 2-pole device offers reliable household protection with a C-curve characteristic that provides optimal tripping between 5In and 10In for short-circuit conditions. The circuit breaker features a rated current of 16A and can be supplied via copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), making it versatile for various installation configurations.
This device is IP20 rated for protection against solid bodies larger than 12.5mm and incorporates maximum energy limitation (Class 3 according to IEC 60898-1). The TX3 MCB can be equipped with Legrand DX3 auxiliaries and accessories, and supports connection to aluminum cable with the appropriate Legrand terminal accessory. Built with environmentally conscious design principles, it complies with all substance-restriction requirements and is halogen-free. The product features a special DIN rail clamp system that allows independent removal even when the fork busbar remains in place, along with a convenient label holder for circuit identification.
The TX3 MCB operates at a rated voltage of 400V with an insulation voltage of 500V and impulse withstand voltage of 4kV. It supports both 50-60 Hz frequencies and features ON/OFF indication printed on the handle with red and green backgrounds for easy status identification. Installation should be performed by qualified electricians in compliance with local electrical codes, and only Legrand-approved accessories should be used for safety and warranty purposes.
