Why Choose the ABB M E2.2...E6.2 24-30 VAC/DC + MC 24V Motor Operator?
The ABB M E2.2...E6.2 24-30 VAC/DC + MC 24V, order code 1SDA073729R1, is an electrical motor operator accessory for ABB SACE Emax 2 air circuit breakers. Designed for the E2.2, E4.2 and E6.2 frame sizes, it enables electrically powered charging of the circuit breaker's closing springs for remote and automated operation.
The motor operator accepts a control supply of 24–30 V AC/DC, making it suitable for low-voltage control systems used in industrial switchboards, critical power installations and automated distribution systems. Once the breaker closes and the springs discharge, the motor mechanism can automatically recharge the closing springs in preparation for the next closing operation.
This version also incorporates a 24 V DC springs-charged electrical indication contact, identified by the MC 24V designation. This provides a remote electrical indication of the charged state of the closing springs, supporting control-panel indication, interlocking and automation functions.
Key Advantages
- Provides motorised spring charging for compatible ABB SACE Emax 2 air circuit breakers.
- Suitable for E2.2, E4.2 and E6.2 Emax 2 frame sizes.
- Operates from a flexible 24–30 V AC/DC control supply.
- Includes 24 V DC springs-charged electrical indication.
- Supports remote and automated circuit-breaker operating sequences.
- Ideal for switchboards where rapid recharging of the closing mechanism is required after breaker operation.
- Genuine ABB accessory engineered for integration with the SACE Emax 2 platform.
Key Features

- Motorised charging of the circuit-breaker closing springs.
- 24–30 V AC/DC rated supply voltage.
- AC/DC actuating voltage type.
- MC 24V springs-charged electrical indication.
- Compatible with E2.2, E4.2 and E6.2 circuit breakers.
- Suitable for remote and automated breaker operation.
- Loose or configurable accessory format.
- Designed specifically for the ABB SACE Emax 2 product class.
- IEC-design accessory for low-voltage power circuit breakers.
Motorised Operation for ABB SACE Emax 2 Circuit Breakers
ABB SACE Emax 2 air circuit breakers use stored-energy operating mechanisms in which charged springs provide the mechanical energy required for closing. A motor operator automates the spring-charging process, reducing the need for manual charging and preparing the breaker for subsequent electrically commanded closing operations.
The 1SDA073729R1 combines a 24–30 V AC/DC motor supply with 24 V DC springs-charged electrical indication. This combination is particularly useful in automated switchboards, generator systems, transfer schemes and remotely controlled distribution installations where breaker readiness needs to be monitored by a control system.
Typical Applications
- Motorised ABB SACE Emax 2 air circuit breakers.
- Automated low-voltage switchboards.
- Remote circuit-breaker control systems.
- Automatic transfer and changeover systems.
- Generator and standby power switchboards.
- Industrial power distribution systems.
- Data centres and critical power installations.
- Switchgear requiring remote springs-charged status indication.
