Why Choose the ABB 1SDA062078R1 SCR T7M-X1 48V AC/DC Shunt Closing Release?
The ABB 1SDA062078R1 is a 48 V AC/DC shunt closing release designed for compatible ABB SACE Tmax T7M and X1 circuit breaker installations. Identified by ABB as SCR T7M-X1 48V AC/DC, this genuine accessory provides electrically initiated closing of a compatible stored-energy circuit breaker mechanism.
Operating from a nominal control voltage of 48 V AC or 48 V DC, the SCR allows a closing command to be issued electrically rather than relying solely on local mechanical operation. This makes it particularly useful in switchboards requiring remote control, automation or centralised operation of compatible T7M-X1 switching equipment.
The 1SDA062078R1 is supplied as a dedicated shunt closing release accessory rather than a complete circuit breaker. ABB specifies this SCR as the cabled 48 V AC/DC version for the T7M platform, with installation carried out as part of the compatible circuit breaker's operating mechanism and control system.
Key Advantages
- Genuine ABB shunt closing release for compatible T7M-X1 equipment.
- Operates from 48 V AC or 48 V DC control power.
- Enables electrical and remote circuit breaker closing.
- Supports automated and centralised switchboard control schemes.
- Dedicated ABB accessory engineered for compatible stored-energy operating mechanisms.
- Cabled SCR configuration for straightforward integration into the appropriate control circuit.
Key Features
- ABB SCR T7M-X1 shunt closing release.
- 48 V AC nominal control voltage.
- 48 V DC nominal control voltage.
- Designed for compatible ABB Tmax T7M / X1 applications.
- Provides electrically commanded closing.
- Suitable for remote circuit breaker operation.
- Cabled accessory version.
- Designed for integration with the breaker operating mechanism.
- IEC product configuration.
- ABB order code 1SDA062078R1.
Remote Electrical Closing for Stored-Energy Circuit Breakers
A shunt closing release converts an electrical control command into the mechanical action required to close a compatible circuit breaker. When the appropriate control voltage is applied to the release, it operates the closing mechanism, allowing the breaker to be controlled from a remote pushbutton, control panel, automation system or other suitable control circuit.
The ABB 1SDA062078R1 provides this function at 48 V AC/DC for compatible T7M-X1 equipment. It is particularly useful where switchgear must be operated remotely or incorporated into an automated power distribution system. For withdrawable T7-T7M installations, the appropriate ABB sliding contact arrangements for the fixed and moving portions are also required where specified by the breaker configuration.
Typical Applications
- Remote closing of compatible ABB T7M-X1 circuit breakers.
- Industrial low-voltage switchboards.
- Automated power distribution systems.
- Remote electrical control panels.
- Building and infrastructure power management systems.
- Switchgear using a 48 V AC/DC control supply.
