Why Choose the ABB TMA 63-630 XT2 3p?
The ABB TMA 63-630 XT2 3p is a genuine thermal-magnetic trip unit designed for 3-pole ABB SACE Tmax XT2 moulded case circuit breakers. Identified by ABB order code 1SDA067232R1, 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 authoritative model designation specifies a 63 A thermal protection rating together with a 630 A magnetic protection setting, providing coordinated protection against sustained overloads and high-current short-circuit conditions.
Designed specifically for the SACE Tmax XT2 platform, the 1SDA067232R1 provides an ABB-matched protection solution for three-pole installations. It is suitable for new circuit-breaker configurations as well as maintenance and replacement applications where the exact TMA 63-630 XT2 3p trip unit is required.

Thermal-Magnetic Protection for SACE Tmax XT2
A thermal-magnetic trip unit combines two complementary protection principles. The thermal element responds to sustained overcurrent associated with overload conditions, while the magnetic element provides rapid operation when current reaches the magnetic short-circuit protection threshold.
The ABB 1SDA067232R1 integrates these functions into a TMA trip unit specifically matched to the three-pole SACE Tmax XT2 platform. Its 63 A / 630 A configuration provides the specified thermal and magnetic characteristics for compatible low-voltage circuit-breaker applications.
Typical Applications
- ABB SACE Tmax XT2 3-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.
