CAL5-11 Auxiliary Contact Block

Why Choose the ABB 1SBN010020R1011 CAL5-11 Auxiliary Contact Block?

The ABB 1SBN010020R1011, also known as the CAL5-11, is a compact and reliable side-mounted auxiliary contact block designed for use with compatible ABB contactors and contactor relays. Part of the ABB CAL5 auxiliary contact range, it provides additional control and signalling contacts for industrial motor control panels, automation systems and electrical control circuits.

This auxiliary contact block features 1 normally open and 1 normally closed instantaneous contact, making it suitable for applications requiring both status feedback and interlocking functions. Its side-mounted design allows it to be clipped onto the right-hand or left-hand side of compatible ABB contactors, helping panel builders expand functionality without unnecessary panel complexity.

With a compact 2-pole configuration, screw terminal connections and a rated insulation voltage of up to 690 V, the CAL5-11 is ideal for auxiliary circuit switching in industrial environments. It is commonly used in motor starters, control panels, machine automation systems and electrical distribution assemblies.

Reliable Auxiliary Switching for Control Circuits

Auxiliary contact blocks such as the ABB CAL5-11 are used to expand the control and signalling capability of contactors and contactor relays. They allow electrical systems to monitor contactor status, create control interlocks or switch auxiliary circuits independently from the main power contacts.

The ABB 1SBN010020R1011 is designed for simple side mounting and secure connection, helping panel builders, machine manufacturers and maintenance engineers add practical control functionality to compatible ABB devices. Its combination of normally open and normally closed contacts makes it particularly useful where both feedback and interlock signals are required.

Typical Applications

• Industrial motor control panels.
• Auxiliary control and signalling circuits.
• Electrical interlocking systems.
• Contactor status feedback circuits.
• Machine automation and process control panels.
• Panel building, maintenance and retrofit applications.

Trusted by Panel Builders and Automation Engineers
