Why Choose the ABB XT2V 160 TMD 8-80 3P F F Circuit Breaker?
The ABB 1SDA067679R1 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 high short-circuit breaking performance.
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 transformer, generator, installation and general power-distribution protection.
With a rated current of 8 A, an adjustable thermal overload setting of 5.6–8 A and a fixed magnetic short-circuit threshold of 80 A, the XT2V 160 TMD 8-80 provides coordinated overcurrent protection. The V performance level delivers a rated ultimate short-circuit breaking capacity of 150 kA at 415 V AC, making this breaker particularly suitable for installations with high prospective fault currents.
