Why Choose the ABB XT2L 160 TMA 80-800 3p F F Circuit Breaker?
The ABB XT2L 160 TMA 80-800 3p F F, order code 1SDA067645R1, is a compact and dependable three-pole moulded-case circuit breaker (MCCB) designed for protection and switching in low-voltage power distribution systems. Part of the ABB SACE Tmax XT2 range, it combines a 160 A frame with a TMA thermomagnetic trip unit rated at 80 A.
The TMA release provides both thermal overload protection and instantaneous magnetic short-circuit protection. Its thermal protection is adjustable from 56–80 A, while the instantaneous short-circuit setting is adjustable from 400–800 A, allowing the breaker to be configured for the requirements of the protected circuit.
The XT2L 160 is supplied in a fixed three-pole configuration with front terminals. Its L performance level provides a rated ultimate short-circuit breaking capacity of 120 kA at 415 V AC, making this breaker suitable for demanding industrial and commercial distribution systems with high prospective fault currents.
