Why Choose the ABB 1SDA073709R1 Emax 2 Geared Motor Device?
The ABB 1SDA073709R1 is a dedicated geared motor device designed for the ABB Emax 2 E1.2 air circuit breaker. Operating from a 48–60 V AC/DC supply, the motor mechanism electrically charges the circuit breaker's closing springs, preparing the breaker for subsequent closing and supporting remote or automated switchgear operation.
As part of the ABB Emax 2 electrical accessory range, the motor operator is engineered specifically for integration with the E1.2 breaker frame. Automatic spring charging reduces the need for manual charging and makes the accessory particularly useful in switchboards, power distribution systems and installations where circuit breaker operation is controlled remotely.
The 1SDA073709R1 is specified as M E1.2 48–60 V AC/DC and supports both AC and DC control supplies within its rated voltage range. Its purpose-designed construction provides a practical solution for motorising the spring-charging mechanism of compatible Emax 2 E1.2 air circuit breakers.
