Detailed Description

The ABB SJ204T (2TAZ144400R0324) is a high-quality 4-pole Miniature Circuit Breaker (MCB) engineered to protect electrical circuits against overloads and short-circuit faults. With a 32A rated current and a C-curve tripping profile, it is suitable for installations that experience moderate inrush currents, such as mixed lighting loads, small motors, distribution circuits, and commercial wiring systems.

This device features a 3kA breaking capacity, making it appropriate for residential, commercial, and light industrial applications where reliable fault interruption is essential. The 4-pole configuration (L1, L2, L3, N) ensures full-phase and neutral isolation, providing comprehensive circuit disconnection during maintenance or fault events.

Built with ABB’s proven thermal-magnetic technology, the SJ204T delivers precise, consistent protection. The modular housing allows easy installation on standard DIN rails, while the robust terminals ensure secure cable connections. The breaker complies with international electrical safety standards, making it a dependable choice for professional electrical installations.
