Why Choose the ABB 1SDA107610R1 TMA 630-6300 XT6 4P Trip Unit?
The ABB 1SDA107610R1, designated TMA 630-6300 XT6 4p InN=50%In, is a four-pole thermomagnetic protection trip unit designed for compatible ABB SACE Tmax XT6 circuit-breaker units. Rated at 630 A, it provides adjustable thermal overload protection and adjustable magnetic short-circuit protection for low-voltage power distribution applications.
The TMA trip unit offers a thermal adjustment range of 0.7–1 × In, corresponding to approximately 441–630 A at the 630 A nominal rating. Its magnetic protection is adjustable from 5–10 × In, corresponding to 3150–6300 A, allowing the protection characteristics to be matched to the requirements of the protected distribution circuit.
This 1SDA107610R1 version is specifically configured for four-pole XT6 applications with neutral protection at 50% of the phase setting. It is supplied as a separate protection trip unit and must be combined with a compatible four-pole XT6 breaking unit to form a complete circuit breaker.
Key Advantages
- Genuine ABB SACE Tmax XT6 thermomagnetic trip unit.
- 630 A nominal current for high-capacity distribution applications.
- Adjustable thermal overload protection from 0.7–1 × In.
- Adjustable magnetic protection from 5–10 × In.
- Magnetic short-circuit setting range of 3150–6300 A.
- Four-pole configuration with 50% neutral protection.
- Designed to combine with a compatible ABB XT6 four-pole breaking unit.
Key Features
- ABB SACE Tmax XT6 protection accessory.
- Trip unit type: TMA thermomagnetic.
- Nominal current: 630 A.
- Thermal adjustment: 0.7–1 × In.
- Thermal setting range: approximately 441–630 A.
- Magnetic adjustment: 5–10 × In.
- Magnetic setting range: 3150–6300 A.
- Number of poles: 4.
- Neutral protection: 50% of phase setting.
- Separate trip unit for use with a compatible XT6 breaking unit.
Adjustable Thermomagnetic Protection for the XT6 Platform
The ABB TMA protection system combines two established protection principles in a single trip unit. The thermal element responds to sustained overload conditions and can be adjusted from 0.7 to 1 times the 630 A nominal current, while the magnetic element responds rapidly to high short-circuit currents and can be adjusted from 5 to 10 times the nominal current.
For four-wire systems, the 1SDA107610R1 incorporates 50% neutral protection. This distinguishes it from the corresponding full-neutral version and makes selection of the correct order code important when configuring an XT6 circuit breaker. As a separate trip unit, the 1SDA107610R1 must be paired with a suitable four-pole XT6 breaking unit rather than being treated as a complete standalone MCCB.
Typical Applications
- ABB SACE Tmax XT6 circuit-breaker assemblies.
- Industrial low-voltage power distribution systems.
- Main and sub-distribution switchboards.
- Commercial and infrastructure electrical distribution.
- Four-wire systems requiring reduced neutral protection.
- Feeder and distribution circuit protection.
- Applications requiring adjustable thermal and magnetic protection.
- Configurable XT6 circuit breakers assembled from separate breaking and protection units.

Frequently Asked Questions
What is the ABB 1SDA107610R1?
The 1SDA107610R1 is a 630 A four-pole TMA thermomagnetic trip unit for compatible ABB SACE Tmax XT6 circuit-breaker units, with adjustable thermal and magnetic protection and 50% neutral protection.
Is the ABB 1SDA107610R1 a complete circuit breaker?
No. The 1SDA107610R1 is the thermomagnetic protection trip unit. It must be combined with a compatible four-pole ABB XT6 breaking unit to create the complete circuit-breaker assembly.
What are the adjustment ranges of the TMA 630-6300 trip unit?
The thermal protection is adjustable from 0.7–1 × In, approximately 441–630 A for this 630 A unit, while the magnetic protection is adjustable from 5–10 × In, corresponding to 3150–6300 A.
What does InN=50%In mean on the ABB 1SDA107610R1?
InN=50%In identifies a four-pole configuration with neutral protection set at 50% of the phase setting. The 1SDA107610R1 is therefore the reduced-neutral version of the 630 A XT6 TMA trip unit.
Which ABB circuit-breaker family is compatible with the 1SDA107610R1?
The 1SDA107610R1 is designed for the ABB SACE Tmax XT6 platform and must be combined with a compatible four-pole XT6 breaking unit.
