ABB CAL5-11 1SBN010020R1011 Auxiliary Contact 1NO+1NC lateral mounting

The ABB CAL5-11 (article 1SBN010020R1011) is a 2-pole side-mounted auxiliary contact block that clips onto ABB A-series contactors and N contactor relays to extend their contact capacity. It provides one normally open (N.O.) and one normally closed (N.C.) instantaneous contact pair and connects via screw terminals. The block is intended for standard industrial environments and can be positioned on either the right or left side of a compatible contactor or relay.

Technical specifications:

• Series: CAL5-11
• ABB article number: 1SBN010020R1011
• EAN: 3471522121073
• Poles: 2
• Contact configuration: 1 N.O. + 1 N.C. (instantaneous)
• Mounting: Side-mounted, clip-on to right or left side
• Terminal type: Screw terminals
• Compatible with: A9 to A75 contactors and N contactor relays

Features and benefits:

• Clips to either the right or left side of the contactor, giving flexibility when arranging components in a control panel
• Screw terminal connections allow straightforward, secure wiring without special tooling
• The 1 N.O. + 1 N.C. instantaneous contact combination covers the most common auxiliary circuit requirements in a single block
• Function marking on the block allows fast identification during installation and maintenance
• Broad compatibility across the A9 to A75 contactor range and N contactor relays simplifies spare-part management

Applications:

• Expanding auxiliary contact capacity on A-series motor starters in industrial motor control panels
• Status signaling and feedback circuits in switchgear assemblies
• Interlocking circuits requiring additional N.O. or N.C. contacts alongside a main contactor
• Auxiliary contact addition to N contactor relays in building and industrial automation systems

Also known as: ABB CAL5-11, CAL5-11 1SBN010020R1011, auxiliary contact block, side-mounted contactor auxiliary contact, ABB 1SBN010020R1011.
