Detailed Description

The ABB SJ202T (2TAZ144200R0254) is a 2-pole Miniature Circuit Breaker (MCB) engineered to protect electrical circuits against overloads and short-circuits. With a 25A rated current and C-curve tripping characteristic, it is ideal for medium-load two-phase circuits such as lighting systems, small motors, and distribution boards in residential, commercial, and light industrial installations.

Featuring a 3kA breaking capacity, this MCB ensures rapid disconnection during short-circuit events, protecting wiring and connected equipment. Its compact, DIN-rail mountable design allows for easy installation, while the thermal–magnetic mechanism provides long-term reliable protection. The 2-pole configuration (L1, L2) ensures full-phase protection for two-phase systems.
