Why Choose the ABB T7L 800 1SDA062703R1 Circuit Breaker?
The ABB 1SDA062703R1 is a high-performance SACE Tmax T7L moulded case circuit breaker (MCCB) designed for protection and control of demanding low-voltage power distribution systems. Identified by ABB as T7L 800 PR332/P LSIG In=800A 4p F F M, it combines an 800 A rated current with the advanced PR332/P electronic trip unit and a stored-energy operating mechanism.
The T7L performance level provides an ultimate short-circuit breaking capacity of 120 kA at 380–415 V AC, making the breaker suitable for industrial installations with high prospective fault currents. Its PR332/P LSIG electronic trip unit provides long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection for comprehensive power distribution protection.
This configuration is a four-pole, fixed circuit breaker with front terminals, enabling switching and protection across all four poles in suitable three-phase distribution systems with neutral conductors. The PR332/P provides adjustable protection functions, while the stored-energy operating mechanism makes the breaker suitable for sophisticated industrial switchboards and power distribution assemblies.

Comprehensive LSIG Protection for Industrial Power Distribution
Moulded case circuit breakers such as the ABB SACE Tmax T7L protect electrical distribution systems against potentially damaging overload, short-circuit and earth-fault conditions. The 1SDA062703R1 combines an 800 A rating with an ultimate breaking capacity of 120 kA at 380–415 V AC, providing robust protection for demanding industrial installations.
The integrated PR332/P LSIG electronic trip unit provides comprehensive adjustable protection. Long-time protection responds to sustained overloads, short-time protection supports selective fault coordination, instantaneous protection provides rapid response to severe short circuits, and earth-fault protection detects ground faults. Its four-pole construction additionally supports applications where the neutral conductor must form part of the circuit-breaker switching and protection arrangement.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and sub-main electrical switchboards.
- Four-pole three-phase distribution systems with neutral conductors.
- Manufacturing and process plant power systems.
- High-current feeder and cable protection.
- Distribution systems requiring earth-fault protection.
- OEM switchgear and electrical panel assemblies.
