Why Choose the ABB T5L 630 TMA 630-6300 Circuit Breaker?
The ABB T5L 630 TMA 630-6300, order code 1SDA054472R1, 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 and rated current with 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 adjustable characteristics allow the breaker to protect high-current feeders and distribution circuits, while the magnetic element provides rapid interruption of severe short-circuit currents.
The T5L performance level is engineered for installations with high prospective fault currents. Its 4-pole fixed construction with front terminals makes the 1SDA054472R1 particularly suitable for three-phase plus neutral distribution systems, industrial switchboards and high-current feeder applications.
