Why Choose the ABB T7L 1000 PR231/P-I 1SDA062817R1 Circuit Breaker?
The ABB 1SDA062817R1 is a high-performance SACE Tmax T7L 1000 moulded case circuit breaker (MCCB) designed for short-circuit protection and switching in demanding low-voltage electrical systems. This configuration combines a 1000 A rated current, three-pole construction and the ABB PR231/P-I electronic trip unit for adjustable instantaneous short-circuit protection.
As part of the ABB SACE Tmax T7 series, the T7L 1000 is engineered for high-current industrial and commercial installations requiring substantial fault-breaking capability. The L performance level provides a rated ultimate short-circuit breaking capacity of 120 kA at 380–415 V AC, supporting reliable protection in systems with high prospective short-circuit currents.
The 1SDA062817R1 is configured as a three-pole fixed circuit breaker with front terminals. Its PR231/P-I electronic release provides adjustable instantaneous protection and is particularly suited to applications where the circuit breaker is required to provide high-capacity short-circuit protection while overload protection is coordinated separately.
Key Advantages
- High-performance ABB SACE Tmax T7L moulded case circuit breaker.
- 1000 A rated current for high-current electrical systems.
- 120 kA ultimate short-circuit breaking capacity at 380–415 V AC.
- PR231/P-I electronic trip unit for adjustable instantaneous protection.
- Three-pole fixed configuration for three-phase installations.
- Front terminals for integration into fixed switchboards and distribution assemblies.
- Suitable for industrial power and motor circuits requiring high fault-interruption capability.

High-Capacity Short-Circuit Protection
The ABB SACE Tmax T7 platform is designed for high-current low-voltage installations where reliable interruption of severe prospective fault currents is essential. The T7L performance level provides an ultimate breaking capacity of 120 kA at 380–415 V AC and up to 200 kA at 220–230 V AC, making it suitable for demanding industrial distribution environments.
The PR231/P-I electronic trip unit provides instantaneous short-circuit protection rather than the LS/I combination used on overload-protection versions of the T7. This makes the breaker particularly useful in applications where overload protection is provided by separate equipment while the MCCB supplies high-capacity fault interruption and circuit isolation.
Typical Applications
- High-current industrial electrical systems.
- Motor circuits with separate overload protection.
- Motor control centres and industrial switchboards.
- Manufacturing and process-industry installations.
- Low-voltage systems with high prospective fault currents.
- Industrial machinery and plant power systems.
- Fixed switchgear requiring high short-circuit breaking capacity.
