Detailed Description

The ABB SJ201T (2TAZ144100R0634) is a 1-pole Miniature Circuit Breaker (MCB) designed to protect single-phase electrical circuits from overloads and short-circuits. With a 63A rated current and C-curve tripping characteristic, it is ideal for high-load single-phase applications in residential, commercial, and light industrial installations.

Featuring a 3kA breaking capacity, this MCB ensures rapid disconnection during short-circuit events, safeguarding both wiring and connected devices. Its compact, DIN-rail mountable design allows for easy installation, while the thermal–magnetic mechanism provides long-term reliable protection. The 1-pole configuration is suitable for standard single-phase circuits.
