Why Choose the ABB T7L 800 PR332/P-LSIG 800 A 3P Fixed Circuit Breaker?
The ABB 1SDA062695R1 is a SACE Tmax T7L moulded-case circuit breaker rated at 800 A, supplied in a 3-pole fixed configuration with front terminals and an ABB PR332/P-LSIG electronic protection release. It is designed for demanding low-voltage power-distribution applications requiring comprehensive overload, short-circuit and earth-fault protection.
The T7L 800 combines an 800 A rated uninterrupted current with a rated voltage of 690 V AC. The L-performance version provides a rated ultimate short-circuit breaking capacity of 120 kA at 400 V AC, 50 Hz, supporting applications with substantial prospective fault currents.
The PR332/P-LSIG solid-state release provides long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. This version also incorporates a stored-energy operating mechanism, combining comprehensive electronic protection with a high-performance T7L breaker platform.

Comprehensive LSIG Protection for High-Current Distribution
The ABB PR332/P-LSIG electronic release provides four principal protection functions. Long-time protection responds to sustained overloads, short-time protection manages high fault currents with controlled timing, instantaneous protection provides rapid interruption of severe short circuits, and the integrated earth-fault function protects against qualifying ground-fault conditions.
Combined with the T7L platform's 120 kA ultimate breaking capacity at 400 V AC, the 1SDA062695R1 provides a comprehensive protection solution for high-current distribution systems where adjustable electronic protection and substantial fault interruption capability are required.
Typical Applications
- Industrial low-voltage power-distribution switchboards.
- Main distribution boards and high-current feeders.
- Three-phase commercial and infrastructure distribution systems.
- Installations with high prospective short-circuit currents.
- Distribution circuits requiring integrated earth-fault protection.
- Fixed MCCB installations requiring comprehensive LSIG electronic protection.
