Why Choose the ABB XT1H 160 TMD 25-450 3P Circuit Breaker?
The ABB XT1H 160 TMD 25-450 3P F F, order code 1SDA080837R1, is a three-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax XT range. Built on the compact XT1 160 A frame, it combines high breaking performance with thermomagnetic protection for low-voltage power-distribution applications.
This XT1H breaker has a 25 A rated current and uses an ABB TMD thermomagnetic trip unit providing overload and short-circuit protection. The product designation specifies a 25–450 A protection range, while the H performance class provides a high short-circuit breaking capability, including 70 kA Icu at 415 V AC.
The 1SDA080837R1 is supplied as a fixed three-pole circuit breaker with front terminals. With a rated operational voltage up to 690 V AC, it is suitable for industrial switchboards, commercial distribution systems, machinery panels and other installations requiring compact and dependable circuit protection.
