Detailed Description

The ABB SJ204T (2TAZ144400R0204) is a robust 4-pole 20A Miniature Circuit Breaker (MCB) engineered to provide dependable thermal-magnetic protection against overload and short-circuit faults. With a C-curve tripping profile, it is ideal for circuits with moderate inrush currents, such as lighting systems, power outlets, distribution boards, and small machinery.

Designed for reliability, the SJ200 series provides a 3kA breaking capacity, suitable for residential, commercial, and light industrial applications. Its 4P configuration (L1, L2, L3, N) ensures coordinated phase and neutral protection, allowing safe isolation of all poles.

Built for ease of installation, the device features a compact modular design, DIN-rail mounting, durable contacts, and a clear status indicator. ABB’s high manufacturing standards ensure long service life and consistent performance.
