ABB 1SDA070961R1

The E2.2S 1250 air circuit breaker is engineered for robust performance in AC environments, rated for 1250 A with a maximum operational voltage of 690 V. It integrates a solid-state release mechanism, ensuring precision in fault management. This model includes four auxiliary contacts and operates efficiently at a power loss of 83 W.

With a mechanical durability of 25,000 cycles and electrical endurance rated for 15,000 cycles at voltages up to 690 V, the circuit breaker is designed for high reliability. Its rated short-circuit breaking capacity varies from 66 kA to 85 kA, depending on the operational voltage, providing extensive protection capabilities.

Compliance with IEC standards, this breaker is suitable for IT networks and offers a rated insulation voltage of 1000 V AC. The terminal connection type is a rear flat horizontal bolt, with a recommended tightening torque of 70 N·m. The environmental sustainability of the E2.2S 1250 is highlighted by its recyclability rate of 79.3%, aligning with contemporary circular design principles.
