ABB 1SDA068621R1 XT4V 160 Ekip LSI In=40A 4P F F moulded case circuit breaker from the SACE Tmax XT series, designed for low-voltage circuit protection in industrial and commercial distribution systems.
The ABB 1SDA068621R1 is a high-performance moulded case circuit breaker (MCCB) from the ABB SACE Tmax XT series, designed to provide accurate and dependable low-voltage circuit protection for industrial, commercial and infrastructure applications. Identified as the XT4V 160 Ekip LSI In=40A 4P F F, this breaker combines compact construction with advanced electronic protection for demanding switchboard and panel installations.
Built for reliable operation, the ABB XT4V 160 MCCB helps protect electrical circuits, feeders and connected equipment against overloads and short-circuit faults. Its Ekip LSI electronic trip unit provides adjustable long-time, short-time and instantaneous protection functions, making it suitable for systems where selectivity, control and dependable fault protection are important.
With a rated current of 40 A, a four-pole fixed configuration and front terminals, the 1SDA068621R1 is ideal for use in low-voltage distribution boards, electrical switchgear, machinery panels and control cabinet assemblies requiring precise MCCB protection in a compact ABB platform.
Moulded case circuit breakers such as the ABB XT4V 160 are used to protect electrical circuits from overloads and short-circuit fault conditions. By interrupting abnormal current safely and reliably, the MCCB helps reduce equipment damage, cable overheating and costly downtime in electrical installations.
The Tmax XT range is designed for modern power distribution environments where compact size, high breaking performance and flexible protection are required. The 1SDA068621R1 is well suited to panel builders, electrical contractors and maintenance engineers working with industrial switchboards and commercial distribution assemblies.
