Why Choose the ABB TMA 630-6300 T6 630 4-Pole Thermomagnetic Trip Unit?
The ABB TMA 630-6300 T6 630 4P, order code 1SDA060348R1, is a thermomagnetic trip unit designed for compatible ABB SACE Tmax T6 moulded case circuit breakers. Part of the proven ABB Tmax T6 series, it provides thermal overload and magnetic short-circuit protection for high-current low-voltage electrical distribution applications.
The trip unit has a rated current of 630 A and combines a thermal element for sustained overload protection with an adjustable instantaneous magnetic element for short-circuit protection. Its magnetic trip threshold I3 is adjustable from 3150 to 6300 A, equivalent to approximately 5–10 times the rated current.
This version is specifically configured for 4-pole Tmax T6 circuit breaker assemblies and has a neutral protection setting corresponding to 50% of the phase rating. Its straightforward thermomagnetic operating principle provides dependable circuit protection without requiring an electronic protection release.

Reliable Thermomagnetic Protection for Tmax T6 Circuit Breakers
Thermomagnetic trip units use two complementary protection principles. The thermal element responds to sustained overload currents that could overheat conductors and equipment, while the magnetic element reacts rapidly to severe short-circuit currents so that the associated circuit breaker can interrupt the fault.
The ABB TMA 630-6300 combines a 630 A rated current with an adjustable 3150–6300 A instantaneous magnetic threshold. In this four-pole version, the neutral protection is calibrated to 50% of the phase rating, making the trip unit suitable for compatible Tmax T6 four-pole distribution configurations.
Typical Applications
- ABB Tmax T6 moulded case circuit breaker assemblies.
- Industrial low-voltage distribution boards.
- Three-phase plus neutral distribution circuits.
- Main and feeder circuit protection.
- Manufacturing and process plant switchgear.
- Machinery and industrial power distribution panels.
