Why Choose the ABB XT1B 160 TMD 160-1600 4P F F InN=50% Moulded Case Circuit Breaker?
The ABB 1SDA066820R1 XT1B 160 TMD 160-1600 4P F F InN=50% is a compact and dependable moulded case circuit breaker (MCCB) from the ABB SACE Tmax XT series. Designed for low voltage power distribution, it provides reliable protection against overloads and short circuits in commercial, industrial and OEM electrical installations.
This four-pole MCCB is fitted with an adjustable thermomagnetic TMD trip unit, combining thermal overload protection with magnetic short circuit protection. The neutral pole is rated at 50% of the phase current, making it suitable for selected four-pole distribution applications where a reduced neutral rating is required.
With a 160 A rated current, XT1 160 A frame size and 18 kA breaking capacity at 415 V AC, the ABB XT1B 160 TMD 160-1600 4P F F InN=50% is well suited to feeder protection, machinery supplies and general low voltage distribution systems requiring robust ABB circuit protection.
