Why Choose the ABB T6L 630 1SDA060208R1 Moulded-Case Circuit Breaker?
The ABB 1SDA060208R1 is a high-performance Tmax T6L 630 three-pole moulded-case circuit breaker (MCCB) designed for protection and control of low-voltage industrial and commercial power distribution circuits. As part of the ABB Tmax T4–T8 range, it combines a 630 A frame with a TMA thermomagnetic trip unit and the high short-circuit performance of the T6L breaker platform.
The breaker incorporates a TMA 630 thermomagnetic trip unit, providing adjustable thermal overload protection together with instantaneous magnetic short-circuit protection. The overload release can be adjusted from 441–630 A, while the instantaneous magnetic release is adjustable from 3150–6300 A, allowing protection settings to be coordinated with the characteristics of the protected circuit.
The 1SDA060208R1 is a fixed, three-pole circuit breaker with front terminals and a rated uninterrupted current of 630 A. The T6L version provides a rated ultimate short-circuit breaking capacity of 100 kA at 415 V AC, making it particularly suitable for demanding distribution systems where high prospective fault currents may be present.

High-Performance Protection for Low-Voltage Distribution
Moulded-case circuit breakers protect conductors, switchgear and connected equipment against damaging overload and short-circuit currents. The TMA trip unit fitted to the ABB T6L 630 combines an adjustable thermal element for sustained overload protection with an instantaneous magnetic element designed to disconnect high-current short circuits rapidly.
With an Icu of 100 kA at 415 V AC, the T6L performance level is suited to installations with substantial prospective fault currents. Its adjustable 441–630 A overload range and 3150–6300 A instantaneous protection range provide flexibility when coordinating the breaker with feeders, distribution equipment and connected loads.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and sub-main feeder protection.
- High-fault-level switchboards and distribution panels.
- Industrial machinery and production facilities.
- Commercial and infrastructure electrical distribution.
- Three-phase circuits requiring adjustable thermomagnetic protection.
