Detailed Description

The ABB SJ202T (2TAZ144200R0404) is a 2-pole Miniature Circuit Breaker (MCB) engineered to protect electrical circuits from overloads and short-circuits. With a 40A rated current and C-curve tripping characteristic, it is suitable for medium-load circuits in residential, commercial, and light industrial installations.

Featuring a 3kA breaking capacity, the SJ202T ensures fast disconnection during short-circuit events, safeguarding wiring and connected equipment. Its compact, DIN-rail mountable design allows for easy installation and maintenance, while the thermal–magnetic mechanism guarantees long-term reliability. The 2-pole configuration (L1, L2) provides full-phase protection for two-phase systems.
