Detailed Description

The ABB SJ203T (2TAZ144300R0324) is a 3-pole Miniature Circuit Breaker (MCB) designed to provide reliable protection for electrical circuits against overloads and short circuits. With a 32A rated current and C-curve tripping characteristic, it is ideal for circuits with moderate inrush currents such as lighting, motors, and distribution boards in residential, commercial, or light industrial applications.

This MCB delivers a 3kA breaking capacity, ensuring safe disconnection during short-circuit events, and is built to comply with international IEC/EN standards. Its compact design allows for easy DIN rail installation, and the robust thermal–magnetic mechanism ensures long-lasting protection and reliability. The 3-pole configuration (L1, L2, L3) provides full-phase protection in three-phase systems.
