Why Choose the ABB M E1.2 220-250 VAC/DC Motor Operator?
The ABB M E1.2 220-250 VAC/DC, order code 1SDA073711R1, is a geared motor device for automatic charging of the closing springs on compatible ABB SACE Emax 2 E1.2 air circuit breakers. Designed for a 220–250 V AC/DC control supply, it provides motorised spring charging to support electrically operated and remotely controlled circuit-breaker installations.
The motor operator automatically restores the energy stored in the breaker closing springs after an operating cycle, preparing the mechanism for a subsequent closing command. This eliminates the need to manually recharge the closing springs during normal electrically controlled operation and makes the accessory particularly useful in automated switchboards, remote-control systems and power-management applications.
The 1SDA073711R1 is specifically designed for the ABB SACE Emax 2 E1.2 frame. It accepts both AC and DC control supplies within its specified 220–250 V range and is classified as a motor operator accessory for power circuit breakers.

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. After the stored spring energy has been used for breaker operation, the geared motor recharges the mechanism so that the breaker is prepared for its next electrically initiated closing operation.
This functionality is important in remote-control, automatic transfer, power-management and industrial automation systems where repeated manual charging of the breaker mechanism would be impractical. When combined with the appropriate ABB opening, closing and control accessories, the motor operator forms part of a fully 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.
