Why Choose the ABB TMA 630-6300 T6 630 3-Pole Thermomagnetic Trip Unit?
The ABB TMA 630-6300 T6 630 3P, order code 1SDA060347R1, 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 overload and short-circuit protection for high-current low-voltage electrical distribution applications.
The trip unit has a rated current of 630 A and combines thermal overload protection with adjustable magnetic instantaneous protection. Its magnetic trip threshold I3 is adjustable from 3150 to 6300 A, allowing the short-circuit protection response to be matched to the requirements of the protected circuit and installation.
Designed specifically for 3-pole Tmax T6 circuit breaker configurations, the TMA 630-6300 provides straightforward thermomagnetic protection without requiring an electronic protection release. Its robust operating principle makes it suitable for industrial switchboards, feeder circuits and distribution systems requiring dependable overload and short-circuit protection.

Reliable Thermomagnetic Protection for Tmax T6 Circuit Breakers
Thermomagnetic trip units protect electrical circuits using two complementary operating principles. The thermal element responds to sustained overload currents, while the magnetic element reacts rapidly to high short-circuit currents, enabling the associated circuit breaker to disconnect the affected circuit when damaging overcurrent conditions occur.
The ABB TMA 630-6300 combines a 630 A nominal current rating with an adjustable 3150–6300 A magnetic threshold. This allows compatible Tmax T6 circuit breaker assemblies to provide robust protection for high-current feeders, distribution circuits and industrial electrical equipment.
Typical Applications
- ABB Tmax T6 moulded case circuit breaker assemblies.
- Industrial low-voltage distribution boards.
- Main and feeder circuit protection.
- Manufacturing and process plant switchgear.
- High-current three-phase distribution systems.
- Machinery and industrial power distribution panels.
