1SDA073713R1 ABB M E1.2 380-415 VAC Motor Operator

Why Choose the ABB M E1.2 380-415 VAC Motor Operator?

The ABB M E1.2 380-415 VAC, order code 1SDA073713R1, is a geared motor device / motor operator designed for compatible ABB SACE Emax 2 E1.2 air circuit breakers. Operating from a 380–415 V AC control supply, it provides motorised charging of the circuit breaker's stored-energy closing mechanism for electrically controlled and automated installations.

The motor operator automatically recharges the breaker closing springs after their stored energy has been used, preparing the operating mechanism for a subsequent closing operation. This reduces the need for manual spring charging and makes the accessory particularly useful in remotely controlled switchboards, automated power distribution systems and installations requiring repeated electrical operation.

The 1SDA073713R1 is designed specifically for the ABB SACE Emax 2 E1.2 frame and uses an AC control supply within the specified 380–415 V range. ABB classifies the device as a motor operator for power circuit breakers, providing an original accessory solution for motorising the E1.2 stored-energy mechanism.

Automatic Spring Charging for Remote Circuit-Breaker Operation

The ABB M motor operator performs the mechanical task of automatically charging the E1.2 circuit breaker's closing springs. Once the stored spring energy has been discharged during operation, the geared motor recharges the mechanism so that the breaker can be prepared for a subsequent electrically initiated closing operation.

This functionality is particularly valuable in remote-control, automatic transfer, power-management and industrial automation systems where manual spring charging would be impractical. When combined with the appropriate ABB opening, closing and signalling accessories, the motor operator supports a comprehensive electrically controlled SACE Emax 2 installation.

Typical Applications

• Motorised ABB SACE Emax 2 E1.2 air circuit breakers.
• Automatic charging of circuit-breaker closing springs.
• Remote circuit-breaker control systems.
• Automatic transfer and power-management systems.
• Industrial low-voltage switchboards.
• Automated electrical distribution systems.
• Generator and transformer distribution switchgear.
• Commercial, industrial and infrastructure power distribution.
