The ABB 1SDA067678R1 is a high-performance moulded-case circuit breaker (MCCB) designed for reliable protection of low-voltage power distribution systems. Part of the ABB SACE Tmax XT series, the XT2V 160 combines a compact 160 A frame platform with a TMD thermomagnetic release and the high breaking performance associated with the XT2V configuration.
This circuit breaker features a fixed three-pole configuration with front terminals and a TMD thermomagnetic release. Its adjustable thermal element protects against sustained overload conditions, while the fixed magnetic element provides rapid operation during short-circuit faults, making it suitable for industrial and commercial electrical distribution applications.
With a rated current of 6.3 A, an adjustable thermal overload setting of 4.41–6.3 A and a magnetic short-circuit threshold of 63 A, the XT2V 160 TMD 6.3-63 provides coordinated overcurrent protection. The XT2V version offers a rated ultimate short-circuit breaking capacity of 150 kA at 415 V AC, providing robust protection where high prospective fault currents may be present.
Thermomagnetic circuit breakers combine thermal and magnetic protection mechanisms to protect electrical installations against damaging overcurrent conditions. The adjustable thermal element responds to sustained overloads, while the magnetic element operates rapidly when short-circuit current reaches the specified threshold.
The ABB Tmax XT2V platform is designed for applications requiring compact construction and high short-circuit interruption performance. With its 150 kA Icu rating at 415 V AC, the XT2V configuration is particularly suited to distribution systems where prospective fault currents demand a higher breaking-capacity circuit breaker.
