Why Choose the ABB XT1H 160 TMD 25-450 4P Circuit Breaker?
The ABB XT1H 160 TMD 25-450 4P F F, order code 1SDA080852R1, is a four-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax XT range. Built on the compact XT1 160 A frame, it combines high short-circuit performance with thermomagnetic protection for low-voltage power-distribution applications.
This XT1H circuit breaker has a 25 A rated current and incorporates an ABB TMD thermomagnetic trip unit. Its thermal overload setting is adjustable from 17.5–25 A, while the instantaneous magnetic short-circuit setting is fixed at 450 A, providing coordinated protection against sustained overloads and high fault currents.
The 1SDA080852R1 is supplied as a fixed four-pole circuit breaker with front terminals. It supports rated operational voltages up to 690 V AC and provides an ultimate short-circuit breaking capacity of 70 kA at 415 V AC, making it suitable for industrial switchboards, commercial distribution systems, machinery panels and OEM electrical equipment.
