ABB CA4-01 1SBN010110R1001 Auxiliary Contact 1NC front mounting

ABB CA4-01 (article 1SBN010110R1001) is a single-pole, front-mounted auxiliary contact block that attaches directly to ABB AF(C)09 through AF96 contactors and NF(C)(Z)(B) contactor relays to add a normally closed (N.C.) instantaneous contact. Wiring is made through screw terminals, and the block is designed for use in standard industrial environments.

Technical specifications:

• Series: CA4-01
• ABB article number: 1SBN010110R1001
• EAN: 3471523130029
• Poles: 1-pole
• Contact configuration: 1 N.C. (normally closed) instantaneous
• Mounting: Front mounted
• Terminal type: Screw terminals
• Compatible with: AF(C)09(Z)(B)...96 contactors and NF(C)(Z)(B) contactor relays
• Environment: Standard industrial

Features and benefits:

• Front-mounted design allows the block to be added to compatible contactors without modifying the base unit or disturbing the main circuit wiring
• Single N.C. instantaneous contact enables interlocking, status signalling, and control circuit functions directly from the contactor body
• Screw terminals provide a secure and accessible wiring connection suited to panel assembly and maintenance
• Broad compatibility across AF09 to AF96 contactors and NF contactor relays gives flexibility for different panel configurations
• Rated for standard industrial environments, making it a practical choice for everyday motor control and automation panels

Applications:

• Interlocking in reversing motor starter circuits, using the N.C. contact to block simultaneous energisation of forward and reverse contactors
• Contactor state feedback in control panels, providing an open-contact signal when the contactor is energised
• Expanding auxiliary contact capacity on existing AF or NF series contactors in industrial switchgear and MCC panels
• Safety and interlock functions in standard industrial control and automation applications

Also known as: ABB CA4-01, CA4-01 1SBN010110R1001, auxiliary contact block ABB, 1NC front-mounted auxiliary contact, ABB contactor auxiliary block.
