Why Choose the ABB T7L 800 PR331/P-LSIG 800A 4-Pole Circuit Breaker?
The ABB 1SDA062700R1 is a Tmax T7L 800 moulded-case circuit breaker equipped with a PR331/P-LSIG electronic trip unit. Rated at 800 A and configured with 4 poles, it provides comprehensive electronic protection for demanding low-voltage power-distribution systems.
The PR331/P electronic trip unit provides LSIG protection, combining long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. This combination provides broad fault coverage and supports coordinated protection within industrial and commercial distribution networks.
The authoritative ABB designation T7L800PR331/PLSIGIn=800A4pFF specifies the T7L 800 frame, 800 A rated current, PR331/P-LSIG protection, four-pole configuration and fixed breaker with front terminals. ABB order code 1SDA062700R1 identifies this exact configuration.

PR331/P-LSIG Electronic Protection
The PR331/P-LSIG trip unit combines four principal protection functions. Long-time protection responds to sustained overload conditions, short-time protection provides a coordinated response to short-circuit currents, and instantaneous protection provides rapid interruption under severe short-circuit conditions.
The additional G earth-fault protection function provides dedicated protection against earth-fault conditions. Together, these LSIG functions make the 800 A T7L breaker suitable for distribution systems requiring comprehensive electronic overload, short-circuit and earth-fault protection.
Typical Applications
- Main low-voltage distribution switchboards.
- Industrial power-distribution systems.
- High-current feeder protection.
- Distribution circuits requiring earth-fault protection.
- Commercial and infrastructure electrical systems.
- Four-pole power-distribution circuits.
- OEM switchgear and electrical distribution panels.
