Why Choose the ABB XT1N 160 TMD 25-450 1SDA080829R1 Circuit Breaker?
The ABB 1SDA080829R1 is a three-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax XT family, designed for protection and isolation in low-voltage electrical distribution systems. The compact XT1N 160 frame makes it suitable for industrial, commercial and OEM applications where dependable circuit protection must be integrated into space-conscious switchboards and control panels.
This breaker uses a TMD thermomagnetic trip unit with a rated current of 25 A and instantaneous magnetic protection at 450 A. The combination of thermal overload and magnetic short-circuit protection provides dependable protection for cables, distribution circuits and connected equipment without requiring an electronic trip unit.
The 1SDA080829R1 features a three-pole configuration, fixed installation and front terminals. Its XT1N construction combines the 160 A frame size with a 25 A TMD release, making it a practical solution for lower-current three-phase feeders that require the flexibility and accessory platform of the ABB Tmax XT1 family.

Thermomagnetic Protection for Low-Voltage Distribution
Thermomagnetic moulded case circuit breakers provide two complementary protection functions. The thermal element responds to sustained overload conditions that could otherwise overheat cables and connected equipment, while the magnetic element responds rapidly when a high short-circuit current occurs. In the ABB 1SDA080829R1, the 25 A TMD release is paired with a 450 A instantaneous magnetic threshold.
This straightforward protection principle makes the XT1N 160 TMD suitable for many conventional low-voltage distribution applications where sophisticated electronic protection is unnecessary. Combined with the compact XT1 frame, three-pole construction, fixed mounting and front terminals, it provides a practical circuit protection solution for panel builders, OEMs and electrical distribution installations.
Typical Applications
- Three-phase low-voltage distribution circuits.
- Industrial electrical switchboards.
- Commercial distribution panels.
- Machine and equipment power supplies.
- OEM electrical control panels.
- Cable and feeder protection.
- General-purpose electrical distribution requiring thermomagnetic protection.
