Why Choose the ABB 1SDA068445R1 XT4H 160 MCCB?
The ABB 1SDA068445R1 is a high-performance Tmax XT4H moulded case circuit breaker (MCCB) designed for reliable magnetic protection in low-voltage electrical distribution and motor protection applications. As part of the advanced ABB SACE Tmax XT range, this fixed three-pole circuit breaker combines compact construction, high breaking performance and dependable ABB engineering for demanding industrial installations.
Featuring an MA magnetic release, the XT4H provides instantaneous short-circuit protection without thermal overload protection, making it particularly suitable for motor circuits where overload protection is provided separately by a dedicated overload relay or motor protection device. Its fixed mounting format and front terminal arrangement support efficient installation in switchboards, control panels and OEM machinery.
With a 52 A rated current, three-pole configuration and adjustable instantaneous magnetic setting from 260 to 520 A, the ABB 1SDA068445R1 is ideal for industrial protection systems requiring reliable fault interruption, safe switching and long-term operational performance.
