Why Choose the ABB T7V 800 1SDA062711R1 Circuit Breaker?

The ABB 1SDA062711R1 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 LSIG electronic trip unit for comprehensive overload, short-circuit and earth-fault protection.

The T7V performance level provides exceptionally high fault-clearing capability, with a rated ultimate short-circuit breaking capacity of 150 kA at 380–415 V AC. The breaker is also 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 LSIG trip unit provides long-time overload protection, selective short-time protection, instantaneous short-circuit protection and earth-fault protection. Combined with its 800 A rated current, three-pole construction and fixed front-terminal configuration, the 1SDA062711R1 provides a robust 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.
  • 150 kA ultimate breaking capacity at 380–415 V AC for installations with very high prospective fault currents.
  • PR332/P LSIG electronic trip unit provides comprehensive adjustable protection.
  • Integrated earth-fault protection (G) for enhanced distribution-system protection.
  • Three-pole fixed configuration with front terminals for straightforward switchboard integration.
  • Part of ABB's established SACE Tmax T7 moulded-case circuit-breaker platform.

Key Features

  • ABB SACE Tmax T7V 800 circuit breaker.
  • 800 A rated current (In).
  • Three-pole configuration.
  • PR332/P LSIG electronic trip unit.
  • Long-time overload protection (L).
  • Selective short-time protection (S).
  • Instantaneous short-circuit protection (I).
  • Earth-fault protection (G).
  • 150 kA Icu at 380–415 V AC.
  • Fixed installation with front terminals.

Advanced LSIG Protection for High-Fault-Level Distribution

The PR332/P LSIG electronic trip unit provides four complementary protection functions for demanding distribution networks. Long-time protection responds to sustained overload conditions, short-time protection enables selective coordination during short circuits, instantaneous protection provides rapid interruption of severe faults, and the earth-fault function detects potentially damaging current flowing outside the intended phase conductors.

Combined with the T7V breaker's exceptional 150 kA Icu at 380–415 V AC, these LSIG functions make the 1SDA062711R1 particularly suitable for high-capacity distribution networks close to transformers or other sources capable of delivering substantial fault currents. Its fixed front-terminal configuration provides 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 distribution networks.
  • Transformer secondary distribution and protection.
  • Manufacturing, process and infrastructure electrical installations.
  • OEM switchgear requiring adjustable LSIG protection.
