Why Choose the ABB XT1S 160 TMD 40-450 4p F F Circuit Breaker?
The ABB XT1S 160 TMD 40-450 4p F F 1SDA080849R1 is a 4-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax XT range, designed for dependable overload and short-circuit protection in low-voltage power distribution systems. Built on the compact XT1 160 frame, it has a 40 A rated current and 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 protection against sustained overload conditions and high-current short circuits.
The breaker is supplied in a fixed, 4-pole configuration with front terminals and has a rated voltage of 690 V. The XT1S performance level provides an ultimate short-circuit breaking capacity of 50 kA at 415 V AC, making this MCCB suitable for industrial, commercial and OEM electrical distribution applications requiring four-pole switching and protection.
Key Advantages

Four-Pole 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 setting 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 breaker's 4-pole configuration and XT1S short-circuit performance, this makes the 1SDA080849R1 suitable for three-phase distribution systems where switching and protection of an additional neutral conductor is required by the system design.
Typical Applications
- Industrial low-voltage distribution boards.
- Commercial electrical distribution systems.
- Three-phase and neutral feeder protection.
- Four-pole electrical distribution circuits.
- Machinery and industrial control panels.
- OEM electrical equipment and assemblies.
- Switchboards and distribution enclosures.
