Why Choose the ABB M E2.2...E6.2 380-415 VAC + MC 24V Motor Operator?
The ABB M E2.2...E6.2 380-415 VAC + MC 24V, order code 1SDA073734R1, is a dedicated motor operator and spring-charging accessory for compatible ABB SACE Emax 2 air circuit breakers. Designed for the E2.2, E4.2 and E6.2 frame sizes, it automatically charges the circuit breaker's stored-energy closing springs to support electrical, remote and automated breaker operation.
The motor operator eliminates the need to manually recharge the closing springs during normal electrically operated service. Once the springs require charging, the motor mechanism restores the stored energy needed for the next closing operation, making it particularly valuable in remotely controlled switchboards, automatic transfer systems and industrial power management installations.
This configuration is designed for a 380–415 V AC motor supply and includes the specified MC 24 V component. Its compatibility across the Emax 2 E2.2 to E6.2 platform makes the 1SDA073734R1 a practical ABB-engineered solution for motorised low-voltage circuit-breaker installations.

Automatic Spring Charging for Motorised Switchgear
ABB SACE Emax 2 air circuit breakers use a stored-energy mechanism to provide the energy required for closing. A motor operator automatically recharges these closing springs, allowing the circuit breaker to be prepared for its next closing operation without manual spring charging.
The ABB 1SDA073734R1 provides this motorised spring-charging functionality for E2.2, E4.2 and E6.2 breakers using a 380–415 V AC supply. This makes it well suited to automated power distribution systems where dependable remote breaker operation and rapid preparation for subsequent switching commands are required.
Typical Applications
- Motorised ABB SACE Emax 2 air circuit breakers.
- Industrial low-voltage distribution switchboards.
- Remote-operated electrical switchgear.
- Automatic transfer and power switching systems.
- Industrial power management and automation systems.
- Commercial and infrastructure electrical distribution installations.
