Detailed Description

The ABB SJ201T (2TAZ144100R0164) is a 1-pole Miniature Circuit Breaker (MCB) designed to protect single-phase electrical circuits from overloads and short-circuits. With a 16A rated current and C-curve tripping characteristic, it is ideal for light to medium-load single-phase circuits, including lighting, small appliances, and distribution panels in residential, commercial, and light industrial installations.

This MCB features a 3kA breaking capacity, ensuring rapid disconnection during short-circuit events to safeguard 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 1-pole configuration offers full protection for standard single-phase circuits.
