The ABB 1SDA067425R1 is a robust moulded case circuit breaker (MCCB) from the advanced ABB Tmax XT series, designed to provide reliable protection for low voltage electrical distribution systems. Identified as XT1N 160 TMD 125-1250 4p F F InN=50%, this breaker is suitable for industrial, commercial and panel building applications where dependable circuit protection is essential.
This ABB Tmax XT1N circuit breaker combines compact dimensions with strong electrical performance, making it ideal for use inside control panels, distribution boards and machinery power circuits. The integrated TMD thermomagnetic release provides overload and short-circuit protection, helping safeguard cables, equipment and downstream electrical systems.
With a rated current of 125 A, a four-pole configuration and front terminals, the 1SDA067425R1 is designed for fixed installation in low voltage assemblies. Its neutral pole is rated at 50% of the phase current, making it suitable for selected four-pole distribution applications where neutral protection and switching are required.
Moulded case circuit breakers such as the ABB Tmax XT1N protect electrical installations by disconnecting the circuit during overload or short-circuit conditions. This helps reduce the risk of equipment damage, cable overheating and unplanned downtime in demanding electrical environments.
The ABB 1SDA067425R1 is well suited for panel builders, electrical contractors and maintenance engineers who require a compact, dependable and standards-compliant MCCB for fixed installation. Its thermomagnetic trip unit provides straightforward and effective protection for a wide range of power distribution applications.
