Why Choose the ABB T5L 630 TMA 500-5000 Circuit Breaker?
The ABB T5L 630 TMA 500-5000, order code 1SDA054471R1, is a high-performance 4-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax T5 range. Designed for demanding low-voltage power distribution, it combines a 630 A frame with a 500 A TMA adjustable thermomagnetic release.
The TMA thermomagnetic trip unit provides thermal overload and instantaneous magnetic short-circuit protection without requiring an electronic release. Its overload setting is adjustable from 350–500 A, while the instantaneous magnetic threshold is adjustable from 2500–5000 A, allowing protection to be coordinated with the connected circuit.
The T5L performance level delivers an ultimate short-circuit breaking capacity of 120 kA at 400 V AC. With 4-pole fixed construction, front terminals and IP20 protection, the 1SDA054471R1 is well suited to industrial switchboards, feeder circuits and three-phase plus neutral distribution systems with high prospective fault currents.

Adjustable Thermomagnetic Circuit Protection
The ABB TMA release combines two established protection principles in a robust trip unit. Its thermal element responds to sustained overload currents and is adjustable from 350–500 A, while the magnetic element provides rapid operation during severe short circuits with an adjustable instantaneous threshold of 2500–5000 A.
This adjustable thermomagnetic design enables protection settings to be matched to the characteristics of the protected conductors and load without requiring an electronic trip unit. Combined with the T5L platform's high interruption capability and four-pole construction, the 1SDA054471R1 provides dependable protection for demanding three-phase plus neutral distribution systems.
Typical Applications
- Industrial low-voltage distribution switchboards.
- Three-phase plus neutral electrical systems.
- Main and feeder circuit protection.
- Manufacturing and process plants.
- Commercial building power distribution.
- Industrial machinery power circuits.
- Installations requiring high breaking capacity and adjustable thermomagnetic protection.
