Detailed Description

The ABB SJ202T (2TAZ144200R0204) is a 2-pole Miniature Circuit Breaker (MCB) designed to protect electrical circuits from overloads and short-circuits. With a 20A rated current and C-curve tripping characteristic, it is ideal for medium to light-load two-phase circuits, including lighting systems, small motors, and distribution panels in residential, commercial, and light industrial applications.

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