ABB T7S 1250 Series Miniature Circuit Breaker, 1250A Current, 690V ac Rated Voltage - 1SDA062891R1 T7S-M 1250A PR232-LSI FF

This miniature circuit breaker is designed to protect low-voltage distribution systems by interrupting fault currents and providing controlled disconnection in industrial installations. It is a four-pole device with fixed terminals and a solid-state trip mechanism, intended for applications requiring high continuous current handling and Compact electrical protection within three-phase systems up to 690Vac.

Features and Benefits:

• 1250A current rating delivers high continuous current capacity
• 30kA breaking capacity limits fault energy during short circuits
• Solid-state release ensures precise electronic tripping behaviour
• Fixed Terminal arrangement provides secure, vibration-resistant connections
• Four-pole configuration supports simultaneous multi‑phase disconnection

Applications

• Suitable for heavy-duty distribution panels in factories
• Used for protection of three-phase motor feeders
• Ideal for centralised busbar installations requiring four-pole isolation
• Can be used for switchgear in commercial power distribution
• Used with systems requiring Compact 690V protection

What tripping mechanism does it use?

It employs a solid-state tripping mechanism that provides electronic release and controlled fault response.

How many poles and what Terminal type are provided?

The device is a four-pole unit fitted with fixed terminals for secure connection.

What voltage and breaking capacity does it support?

It is rated for operation up to 690Vac and has a breaking capacity of 30kA.

Which standards and restrictions apply to its materials?

The design conforms to IEC standards and meets RoHS material restrictions.
