Why Choose the ABB 1SDA060473R1 TMA 800-8000 T6 800 4-Pole Trip Unit?

The ABB 1SDA060473R1 is a four-pole thermomagnetic trip unit designed for compatible ABB SACE Tmax T6 800 moulded-case circuit breakers. Identified as TMA 800-8000 T6 800 4p InN=100%In, it provides thermal overload and instantaneous short-circuit protection for demanding low-voltage power distribution applications.

As part of the ABB SACE Tmax T6 protection system, the TMA release combines dependable thermal and magnetic protection in a compact mechanical trip unit. Its rated current is 800 A, while the instantaneous short-circuit protection setting extends from 4000–8000 A, enabling protection to be matched to the requirements of the electrical installation.

This version is designed for four-pole T6 800 circuit breakers and features a 100% rated neutral, meaning the neutral pole is protected at the same current rating as the phase conductors. The trip unit is suitable for AC and DC applications and provides a robust protection solution for industrial distribution boards, switchboards and high-current electrical systems.

Key Advantages

  • Genuine ABB SACE Tmax T6 thermomagnetic trip unit.
  • 800 A rated current for high-current distribution applications.

  • Four-pole configuration with protection of the neutral conductor.
  • Neutral rated at 100% of phase current for full neutral protection.

Key Features

  • ABB SACE Tmax T6 series.
  • TMA thermomagnetic release technology.
  • 800 A rated current.
  • Four-pole configuration.
  • 100% rated neutral (InN = 100% In).
  • Instantaneous short-circuit protection adjustable from 4000–8000 A.
  • Designed for compatible Tmax T6 800 moulded-case circuit breakers.
  • Suitable for AC and DC electrical systems.
  • ABB order code 1SDA060473R1.

Reliable Thermomagnetic Protection for Power Distribution

Thermomagnetic releases protect electrical distribution systems using two complementary operating principles. The thermal element responds to sustained overload currents, while the magnetic element provides rapid tripping when a high short-circuit current occurs. This combination provides dependable protection without requiring an external electronic power supply.

The ABB 1SDA060473R1 is engineered for T6 800 applications requiring four-pole protection. Its 4000–8000 A instantaneous protection range and fully rated neutral make it particularly suitable for three-phase four-wire systems where both phase and neutral conductors require coordinated protection.

Typical Applications

  • Industrial low-voltage power distribution systems.
  • ABB Tmax T6 800 circuit-breaker installations.
  • Three-phase four-wire electrical networks.
  • Main and sub-distribution switchboards.
  • Industrial machinery and manufacturing facilities.
  • Commercial and infrastructure power distribution assemblies.
