Why Choose the ABB T7L 800 PR231/P-LS/I 800 A 4P Fixed Circuit Breaker?
The ABB 1SDA062682R1 is a SACE Tmax T7L moulded-case circuit breaker rated at 800 A, supplied in a 4-pole fixed configuration with front terminals and an ABB PR231/P-LS/I electronic protection release. It is designed for demanding low-voltage power-distribution applications requiring dependable overload and short-circuit protection.
The T7L 800 combines an 800 A rated current with a rated operational voltage of 690 V AC. Its L-performance level provides a rated ultimate short-circuit breaking capacity of 120 kA at 400 V AC, making the breaker suitable for installations with high prospective fault currents.
The PR231/P-LS/I electronic release provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. Together with its fixed four-pole construction and front connections, the 1SDA062682R1 provides a robust protection solution for industrial, commercial and infrastructure switchboards.

LS/I Electronic Protection for Demanding Distribution Systems
The ABB PR231/P-LS/I release combines three essential protection functions. Long-time protection responds to sustained overload conditions, short-time protection provides controlled response to high fault currents, and instantaneous protection rapidly trips the circuit breaker when severe short-circuit currents occur.
Combined with the T7L breaker's 120 kA Icu at 400 V AC, the electronic release makes the 1SDA062682R1 well suited to high-current distribution systems where both overload protection and substantial short-circuit interruption capability are required.
Typical Applications
- Industrial low-voltage power-distribution switchboards.
- Main distribution boards and high-current feeders.
- Commercial and infrastructure electrical distribution.
- Four-pole power-distribution circuits.
- Installations with high prospective short-circuit currents.
- Fixed MCCB installations requiring LS/I electronic protection.
