Why Choose the ABB XT1S 160 TMD 32-450 3p F F Circuit Breaker?
The ABB XT1S 160 TMD 32-450 3p F F 1SDA080833R1 is a 3-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax XT range, designed for dependable overload and short-circuit protection in low-voltage electrical distribution systems. Built on the compact XT1 160 frame, it combines a 32 A rated current with ABB's S short-circuit performance level.
Protection is provided by a TMD thermal-magnetic trip unit. The thermal protection setting is adjustable across 22.4–32 A, while the instantaneous short-circuit current setting is 450 A, providing coordinated protection against both 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 and 50 kA at 380 V AC, making it suitable for demanding industrial and commercial distribution applications.
Key Advantages
- Thermal-magnetic protection against overload and short-circuit conditions.
- Adjustable thermal setting range of 22.4–32 A.
- Instantaneous short-circuit setting of 450 A.

Thermal-Magnetic Protection for Low-Voltage Distribution
The TMD thermal-magnetic trip unit combines two complementary protection functions. The thermal element responds to sustained overload conditions and can be adjusted between 22.4 A and 32 A, allowing the protection setting to be matched more closely to the connected circuit and load.
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 1SDA080833R1 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 and installation protection applications.
