Description
ABB 1SDA100389R1
SACE Tmax XT5N 630 | 630 A MCCB | 4-Pole | Adjustable Thermal-Magnetic Trip | Fixed Mounting
Product Detailed Description
The ABB 1SDA100389R1 is a SACE Tmax XT5N 630 molded case circuit breaker (MCCB) designed for low-voltage power distribution and circuit protection. It has a rated current of 630 A, four poles, fixed mounting, and front terminals. The breaker is equipped with an adjustable thermal-magnetic TMA trip unit, with a neutral rated at 100% of the phase current. The TMA trip unit provides overload protection and an adjustable instantaneous short-circuit trip function. the model as an XT5N 630 with an instantaneous trip adjustment range of 3,150–6,300 A. It is suitable for compatible three-phase and neutral distribution circuits in industrial and commercial switchboards.
