Why Choose the ABB M E1.2 380-415 VAC + MC 24V Motor Operator?
The ABB M E1.2 380-415 VAC + MC 24V, order code 1SDA073720R1, is a motor operator for ABB SACE Emax 2 E1.2 air circuit breakers, designed to automatically charge the breaker’s closing springs and prepare the operating mechanism for electrical closing. The motor operates from a 380–415 V AC supply and is supplied with a 24 V DC MC auxiliary contact for electrical indication of the spring-charged condition.
As part of the ABB SACE Emax 2 electrical accessory range, this motor operator enables automatic recharging of the stored-energy mechanism after the closing springs have been discharged. This makes it particularly valuable in remotely operated switchboards and automated power-distribution systems where the circuit breaker must be kept ready for subsequent closing commands without routine manual spring charging.
The 1SDA073720R1 is specifically designed for the compact Emax 2 E1.2 frame. Its motor supply is rated for both 50 Hz and 60 Hz AC systems, while the integrated MC contact provides a 24 V DC signalling interface for monitoring the charged state of the mechanism within control, automation and supervisory systems.

Reliable Motorised Spring Charging for Emax 2
ABB SACE Emax 2 air circuit breakers use a stored-energy operating mechanism in which charged springs provide the mechanical energy required for rapid breaker closing. The M motor operator automates the charging process, restoring the closing springs after discharge so that the circuit breaker can be prepared for another closing operation without requiring routine manual charging.
This functionality is particularly useful in remotely controlled and automated installations. The accompanying MC 24 V DC contact provides electrical feedback when the springs are charged, allowing PLCs, control circuits and supervisory systems to monitor breaker readiness as part of a wider switchgear automation scheme.
Typical Applications
- ABB SACE Emax 2 E1.2 air circuit breakers.
- Industrial low-voltage power-distribution switchboards.
- Remote circuit-breaker operating systems.
- Automatic transfer and power-management systems.
- Generator and critical-power distribution switchgear.
- Automated industrial and infrastructure electrical systems.
