Why Choose the ABB T7V 800 1SDA062712R1 Circuit Breaker?
The ABB 1SDA062712R1 is a high-performance SACE Tmax T7V 800 moulded-case circuit breaker designed for demanding low-voltage power distribution systems. Rated at 800 A, this three-pole breaker combines fixed installation, front terminals and an advanced PR332/P LSIRc electronic trip unit for overload, selective short-circuit, instantaneous short-circuit and residual-current protection.
The T7V performance level provides exceptional fault-clearing capability, including a rated ultimate short-circuit breaking capacity of 150 kA at 380–415 V AC. The breaker is rated for operation up to 690 V AC, making it suitable for high-capacity industrial and commercial distribution networks where substantial prospective fault currents may be present.
The PR332/P LSIRc trip unit combines adjustable long-time, short-time and instantaneous overcurrent protection with an integrated residual-current function. With an 800 A rated current, three-pole construction, fixed mounting and front connections, the 1SDA062712R1 provides a comprehensive protection solution for main switchboards, distribution feeders and critical industrial power systems.
Key Advantages
- High-performance 800 A moulded-case circuit breaker for demanding low-voltage distribution systems.
- PR332/P LSIRc electronic trip unit combines adjustable overcurrent and residual-current protection.

Advanced LSIRc Protection for High-Fault-Level Distribution
The PR332/P LSIRc electronic trip unit provides multiple protection functions within a single circuit-breaker platform. Long-time protection responds to sustained overloads, short-time protection supports selective coordination during short circuits, instantaneous protection provides rapid interruption of severe faults, and the residual-current function provides additional protection by monitoring current leakage towards earth.
Combined with the T7V breaker's 150 kA Icu at 380–415 V AC, these protection functions make the 1SDA062712R1 particularly suitable for high-capacity distribution networks where both substantial short-circuit performance and residual-current monitoring are required. Its fixed construction and front bolted connections provide a robust arrangement for permanent integration into industrial and commercial switchboards.
Typical Applications
- Industrial low-voltage main switchboards.
- Main and sub-main power distribution systems.
- High-fault-level electrical distribution networks.
- Distribution systems requiring residual-current protection.
- Manufacturing, process and infrastructure electrical installations.
- OEM switchgear requiring adjustable electronic LSIRc protection.
