Why Choose the ABB XT1S 160 TMD 40-450 3p F F Circuit Breaker?
The ABB XT1S 160 TMD 40-450 3p F F 1SDA080834R1 is a 3-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax XT range, designed for overload and short-circuit protection in low-voltage power distribution systems. Built on the compact XT1 160 frame, it combines a 40 A rated current with ABB's S short-circuit performance level.
Protection is provided by a TMD thermal-magnetic trip unit. The thermal overload setting is adjustable across 28–40 A, while the instantaneous magnetic short-circuit setting is 450 A, providing coordinated protection against sustained overloads and high-current faults.
The breaker is supplied in a fixed, 3-pole configuration with front terminals. It supports rated operational voltages up to 690 V AC and 500 V DC, with an ultimate short-circuit breaking capacity of 50 kA at 415 V AC, making it suitable for demanding industrial, commercial and OEM electrical distribution applications.

Thermal-Magnetic Protection for Low-Voltage Distribution
The TMD thermal-magnetic trip unit combines two complementary protection functions. Its thermal element responds to sustained overload conditions and can be adjusted between 28 A and 40 A, allowing the overload protection level to be matched to the requirements of the connected circuit.
For high-current short circuits, the magnetic element provides rapid operation at an instantaneous setting of 450 A. Combined with the XT1S breaking performance and compact XT1 frame, this makes the 1SDA080834R1 suitable for protecting feeders, distribution circuits and industrial electrical loads where reliable fault interruption is required.
Typical Applications
- Industrial low-voltage distribution boards.
- Commercial electrical distribution systems.
- Three-phase feeder protection.
- Machinery and industrial control panels.
- OEM electrical equipment.
- Switchboards and distribution enclosures.
- Transformer, generator and installation protection applications.
