Detailed Description

The ABB SJ201T (2TAZ144100R0404) is a 1-pole Miniature Circuit Breaker (MCB) designed to provide reliable protection for single-phase electrical circuits against overloads and short-circuits. With a 40A rated current and C-curve tripping characteristic, it is ideal for medium-load single-phase circuits, including lighting systems, small appliances, and distribution panels in residential, commercial, and light industrial applications.

This MCB features a 3kA breaking capacity, ensuring rapid disconnection during short-circuit events to protect wiring and connected devices. Its compact, DIN-rail mountable design allows easy installation, while the thermal–magnetic mechanism guarantees long-term reliable performance. The 1-pole configuration provides full protection for standard single-phase circuits.
