ABB CAL4-11 1SBN010120R1011 Auxiliary Contact 1NO+1NC lateral mounting

ABB CAL4-11 (article 1SBN010120R1011) is a 2-pole side-mounted auxiliary contact block that clips directly onto ABB AF and NF series contactors and contactor relays. It provides 1 N.O. and 1 N.C. instantaneous contacts through screw terminals, allowing status or control signals to be added to an existing contactor assembly without replacing the main unit. The block is designed for use in standard industrial environments.

Technical specifications:

• Series: CAL4-11
• ABB article number: 1SBN010120R1011
• EAN: 3471523130043
• Pole count: 2-pole
• Contact configuration: 1 N.O. + 1 N.C. instantaneous contacts
• Terminal type: Screw terminals
• Mounting: Side mounted - left or right side of contactor or contactor relay
• Compatible contactors: AF(C)09(Z)(B) through AF(C)96(Z)(B)
• Compatible contactor relays: NF(C)(Z)(B) series
• Environment: Standard industrial

Features and benefits:

• Mounts on either the left or right side of the contactor, offering flexible positioning within a panel layout.
• Combines 1 N.O. and 1 N.C. instantaneous contacts in a single compact block, covering both signaling and interlocking requirements at once.
• Screw terminals deliver secure, tool-tightened wire terminations in line with standard industrial panel wiring practice.
• Function marking is carried on the block itself, supporting fast identification during installation and maintenance.
• Spans the full AF09 to AF96 and NF contactor range, allowing one part number to serve across multiple contactor sizes.

Applications:

• Run or fault indication in motor starter circuits built around ABB AF series contactors.
• Electrical interlocking between contactors in reversing or star-delta starter assemblies.
• Auxiliary output contacts in control panels using NF series contactor relays.
• Expanding available contact points on an installed ABB contactor without changing the main device.
