Why Choose the ABB 1SDA062716R1 T7V 800 Circuit Breaker?
The ABB 1SDA062716R1 is a high-performance four-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax T7 range, engineered for demanding low-voltage power distribution applications. Identified as T7V 800 PR331/P LSIG In=800A 4P F F, it combines an 800 A rated current with ABB's PR331/P electronic trip unit and high short-circuit interruption capability.
The PR331/P electronic trip unit provides comprehensive LSIG protection, incorporating long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. The overload release is adjustable from 320–800 A, while short-time and instantaneous protection settings provide flexibility for coordinating the breaker with upstream and downstream protection devices.
The 1SDA062716R1 is a four-pole fixed circuit breaker with front terminals and lever operating mechanism. Its T7V construction provides an ultimate short-circuit breaking capacity of 150 kA at 380–415 V AC, making it particularly suitable for industrial switchboards and main distribution systems with high prospective fault currents.

PR331/P LSIG Electronic Circuit Protection
The PR331/P electronic trip unit provides four complementary protection functions. The L function protects against sustained overloads, the S function provides delayed short-circuit protection for selective coordination, and the I function provides rapid interruption of severe short-circuit currents. The additional G function provides protection against earth-fault conditions.
Combined with the high-breaking-capacity T7V 800 platform, these LSIG functions make the ABB 1SDA062716R1 suitable for main and feeder circuits where protection coordination and high fault interruption capability are important. Its four-pole configuration also supports three-phase and neutral distribution systems, while the fixed front-terminal construction facilitates integration into compatible low-voltage switchboards.
Typical Applications
- Industrial low-voltage main distribution boards.
- High-current feeder and sub-main protection.
- Four-pole three-phase and neutral distribution systems.
- Manufacturing and process plant switchboards.
- Commercial building electrical distribution.
- Infrastructure and utility distribution assemblies.
- Installations requiring electronic ground-fault protection.
