Why Choose the ABB XT2V 160 TMD 20-300 3p F F Circuit Breaker?
The ABB XT2V 160 TMD 20-300 3p F F, order code 1SDA067683R1, is a high-performance three-pole moulded-case circuit breaker (MCCB) designed for reliable protection and switching in low-voltage electrical distribution systems. Part of the ABB SACE Tmax XT2 range, it combines the compact XT2 160 frame with a TMD thermomagnetic trip unit rated at 20 A.
The TMD release provides thermal overload protection together with instantaneous magnetic short-circuit protection. Its overload setting is adjustable from 14–20 A, while the instantaneous magnetic release is set at 300 A, providing effective protection against sustained overloads and high short-circuit currents.
This XT2V configuration features a fixed mounting arrangement with front terminals and a three-pole construction. The V short-circuit performance level provides an ultimate breaking capacity of 150 kA at 400 V AC, making the breaker particularly suitable for demanding industrial and commercial distribution systems with high prospective fault currents.

High-Performance Thermomagnetic Circuit Protection
Thermomagnetic moulded-case circuit breakers such as the ABB XT2V use a thermal element to protect electrical circuits against sustained overload conditions and a magnetic element to provide rapid interruption during short-circuit faults. This combination provides dependable protection for cables, power distribution equipment and connected loads.
The SACE Tmax XT2 platform combines compact construction with flexible protection options and high interruption performance. The XT2V version is particularly suited to installations where high prospective fault currents require enhanced short-circuit breaking capability while maintaining a compact switchboard footprint.
Typical Applications
- Industrial low-voltage distribution boards.
- Commercial building electrical distribution.
- Three-phase feeder and branch-circuit protection.
- Electrical switchboards and switchgear assemblies.
- Power distribution, cable and equipment protection.
- Installations with high prospective short-circuit currents.
