Why Choose the ABB XT1N 160 TMF 16-450 3P Circuit Breaker?
The ABB XT1N 160 TMF 16-450 3P, order code 1SDA080827R1, is a compact and reliable moulded case circuit breaker (MCCB) designed to protect low-voltage electrical distribution circuits against overloads and short circuits. As part of the ABB SACE Tmax XT series, it combines the compact XT1 frame with a TMF thermomagnetic release for dependable protection in commercial and industrial power-distribution systems.
This circuit breaker has a 16 A rated current and a 450 A instantaneous magnetic trip level. The TMF thermomagnetic release combines thermal overload protection with magnetic short-circuit protection, providing an effective protection solution without requiring an electronic trip unit.
The XT1N 160 is supplied in a three-pole fixed configuration with front terminals and has a rated operational voltage of up to 690 V AC. Its N short-circuit performance level provides a rated breaking capacity of 36 kA at 415 V AC, making it suitable for switchboards, distribution panels, machinery and other low-voltage electrical assemblies.

Reliable Overload and Short-Circuit Protection
Thermomagnetic moulded case circuit breakers such as the ABB XT1N use two complementary protection mechanisms. The thermal element responds to sustained overload conditions, while the magnetic element operates rapidly when high short-circuit current is detected, helping protect conductors and downstream electrical equipment from damaging fault currents.
The XT1N platform combines compact construction with dependable circuit protection for modern low-voltage installations. With a 16 A rated current, 450 A magnetic trip level and 36 kA breaking capacity at 415 V AC, this configuration is well suited to branch circuits, industrial equipment and distribution systems requiring a compact three-pole MCCB.
Typical Applications
- Industrial low-voltage distribution boards.
- Commercial electrical distribution systems.
- Three-phase feeder and branch-circuit protection.
- Machine and production-line electrical panels.
- Switchboards and control panels.
- OEM electrical equipment and distribution assemblies.
