ABB 2CSG060100R1211 TR2 Toroidal Transformer 1Ph 230-400VAC

The ABB TR2 (article 2CSG060100R1211) is a toroidal transformer that serves as the external sensing element for residual current monitors (RCMs). Connected to a compatible RCM relay, it enables detection of leakage currents in the monitored circuit. A single transformer version per diameter is compatible with all relay sensitivity values, simplifying parts selection and stocking.

Technical specifications:

• Series: TR2
• ABB article number: 2CSG060100R1211
• EAN: 8012542020400
• Type: Toroidal transformer - external transformer for RCM systems
• Compatibility: One version per diameter suitable for all relay sensitivity settings

Features and benefits:

• Acts as the external transformer component of an RCM system, enabling leakage current detection when paired with a compatible RCM relay
• Single transformer version per diameter covers all relay sensitivity values, reducing the number of variants to stock
• Works with RCM relays where sensitivity and intervention time are configurable via minidip, allowing system response to be tailored to the application

Applications:

• Residual current monitoring systems requiring a separate external toroidal transformer
• Leakage current detection in industrial and commercial electrical panels
• Earth fault monitoring in machine wiring and building electrical installations
• Installations combining an RCM relay with a remotely or externally mounted toroidal transformer

Also known as: ABB TR2, TR2 toroidal transformer, 2CSG060100R1211, ABB RCM external transformer, ABB leakage current toroidal transformer.
