ABB Auxiliary Contact Block, 4 Contact, 4 NO, CA5-40ERT, Front, 4 A, 690V, 1SBN010042R1040

This auxiliary contact Block provides additional signalling and control contacts for switching equipment in industrial electrical systems. Designed for front mounting, it expands contact capacity and enables auxiliary circuits to monitor or interlock main devices within automation and electrical installations.

• Four normally open contacts deliver supplementary switching capacity
• Front mounting allows straightforward integration into control assemblies
• Screw terminals enable secure, serviceable wiring connections
• Rated insulation voltage 600V supports a range of control voltages
• Contact current rated at 4 A suits modest auxiliary loads
• Operational current Ie 2 A for defined switching performance

• Suitable for use in motor control panels for status feedback
• Ideal for interlock circuits in automation systems
• Used with contactors to extend auxiliary signalling options
• Can be used for control circuit expansion in distribution boards

It is designed to be mounted on the front of compatible switching devices to provide direct-access auxiliary contacts for control and signalling circuits.

Connections are MADE via screw terminals to ensure reliable clamping and straightforward maintenance.

It provides a four-pole arrangement with four normally open contacts to add multiple auxiliary circuits.

It complies with relevant IEC electrical requirements and enclosure protection specifications referenced in international switchgear standards.
