Why Choose the ABB TMA 100-1000 XT2 4p?
The ABB TMA 100-1000 XT2 4p is a genuine thermal-magnetic trip unit designed for 4-pole ABB SACE Tmax XT2 moulded case circuit breakers. Identified by ABB order code 1SDA067255R1, it provides thermal overload and magnetic short-circuit protection functions for compatible XT2 circuit-breaker configurations.
The TMA design combines thermal and magnetic protection in an electromechanical trip unit. The model designation specifies a 100 A thermal protection rating together with a 1000 A magnetic protection setting, providing protection against sustained overload conditions and high-current short circuits.
Designed specifically for the SACE Tmax XT2 platform, the 1SDA067255R1 provides an ABB-matched protection solution for four-pole installations. Its dedicated XT2 compatibility makes it suitable for new switchboard construction, circuit-breaker configuration and maintenance applications requiring this exact TMA 100-1000 XT2 4p trip unit.

Thermal-Magnetic Protection for SACE Tmax XT2
A thermal-magnetic trip unit combines two complementary circuit-protection principles. The thermal element responds to sustained overcurrent associated with overload conditions, while the magnetic element provides rapid operation when current reaches the specified magnetic short-circuit threshold.
The ABB 1SDA067255R1 integrates these functions into a TMA trip unit specifically matched to the four-pole SACE Tmax XT2 platform. Its 100 A / 1000 A configuration provides the specified thermal and magnetic protection characteristics for compatible low-voltage circuit-breaker applications.
Typical Applications
- ABB SACE Tmax XT2 4-pole moulded case circuit breakers.
- Low-voltage distribution switchboards.
- Industrial electrical distribution systems.
- Machinery and equipment distribution panels.
- Commercial electrical installations.
- Replacement or maintenance of compatible XT2 thermal-magnetic trip units.
