Why Choose the ABB T4V-HA 250 TMA 160-1600 Circuit Breaker?
The ABB T4V-HA 250 TMA 160-1600, order code 1SDA083661R1, is a high-performance SACE Tmax T4 moulded case circuit breaker designed for demanding low-voltage AC power distribution applications. This three-pole breaker combines the T4V-HA 250 platform with a TMA 160-1600 thermomagnetic trip unit and is specified for operation at 800 V AC.
As part of the ABB SACE Tmax T4 series, the breaker provides dependable overload and short-circuit protection using thermomagnetic trip technology. The TMA release combines a thermal element for overload protection with a magnetic element for rapid response to high short-circuit currents, providing straightforward protection without requiring an electronic trip unit.
This model is supplied in a three-pole fixed configuration with front terminals. Its 250 A frame, TMA 160-1600 protection unit and 800 V AC application rating make it suitable for compatible industrial distribution systems requiring a robust fixed circuit breaker for higher-voltage AC networks.

Thermomagnetic Protection for High-Voltage AC Distribution
Thermomagnetic circuit breakers combine two complementary protection principles. The thermal element responds to sustained overload currents, while the magnetic element operates rapidly when severe short-circuit currents occur, providing dependable protection for conductors and downstream electrical equipment.
The ABB T4V-HA 250 combines this protection with a three-pole fixed construction and front terminals. Its TMA 160-1600 release and 800 V AC specification make it particularly suited to compatible industrial power distribution systems where robust thermomagnetic protection is required.
Typical Applications
- Industrial low-voltage AC distribution systems.
- Three-phase feeder protection.
- Electrical distribution switchboards.
- Industrial machinery power distribution.
- Power and control panel assemblies.
- Compatible 800 V AC distribution applications.
