1SDA038322R1 ABB Geared Motor Operator 48–60 V AC/DC E1–E6 T8

Why Choose the ABB 1SDA038322R1 Motor Operator?

The ABB 1SDA038322R1 is a genuine 48–60 V AC/DC geared motor operator designed for electrically charging the closing springs of compatible ABB SACE Emax circuit breakers. Part of the ABB New Emax accessory range, it enables the breaker operating mechanism to be prepared automatically for subsequent electrical or remote closing.

The motor operator provides motorised charging of the circuit breaker's stored-energy closing springs, reducing the need for manual spring charging and supporting remotely operated switchgear. Once the springs have been discharged during a closing operation, the geared motor automatically restores the stored energy required for the next closing cycle when its supply is available.

With a rated supply voltage of 48–60 V AC/DC, the 1SDA038322R1 is suitable for low-voltage AC or DC control systems. ABB identifies this accessory as a geared motor device for E1–E6 and T8, making it suitable for compatible SACE Emax and Tmax T8 circuit-breaker installations.

Reliable Motorised Spring Charging for Circuit Breakers

Stored-energy circuit breakers use charged closing springs to provide the mechanical energy required for rapid and reliable closing of the main contacts. A geared motor operator electrically charges these springs, allowing the operating mechanism to be prepared without manual intervention and enabling repeated remote operating sequences.

The ABB 1SDA038322R1 is particularly suited to industrial switchboards and automated distribution systems where compatible circuit breakers must be ready for remote operation. When combined with appropriate opening and closing releases and control equipment, the motor operator supports comprehensive remote circuit-breaker control.

Typical Applications

• Motorised spring charging for ABB circuit breakers.
• Industrial low-voltage switchboards.
• Automated power-distribution systems.
• Remote circuit-breaker operating systems.
• Automatic transfer and power-management schemes.
• Industrial switchgear and control panels.
• ABB SACE Emax E1–E6 and Tmax T8 installations.
