ABB XT1-XT4 Series Auxiliary Contact Block, 250V Rated Voltage, 2 CO Contact Configuration - 1SDA066431R1

This auxiliary contact Block provides an additional set of changeover contacts to extend the switching capabilities of contactors in industrial control systems. It is designed to be mounted alongside compatible contactor ranges to deliver signal switching and status feedback for control circuits in automation and electrical installations.

Features and Benefits:

• Two changeover contacts provide versatile signalling options
• Rated for 250V operation for standard control voltages
• Conforms to IEC 60947-2 for recognised electrical performance
• Compatible with XT-type contactors for straightforward integration
• Offers plug-on attachment to reduce installation time

Applications

• Suitable for adding feedback contacts to contactor control circuits
• Ideal for status signalling in motor control centres
• Used with XT contactors in factory automation panels
• Can be used for interlock and auxiliary switching tasks
• Used for retrofit replacement of worn auxiliary contacts

What contact arrangement does it provide and why is that useful?

It provides two changeover contacts, enabling both normally open and normally closed signalling paths for flexible control logic and interlocking.

Which supply voltages is it intended to handle in control circuits?

It is specified for operation at 250V, covering common control and signalling voltage levels in industrial applications.

How does it integrate with existing contactors mechanically?

It is intended for direct use with XT-type contactors, allowing mechanical and electrical coupling without bespoke mounting adaptors.

What standard governs its electrical characteristics?

Its performance aligns with IEC 60947-2 requirements, indicating compatibility with established specifications for low-voltage switchgear.

Can it serve as a direct replacement component in maintenance work?

Yes, it is suitable as a replacement auxiliary contact Block for compatible XT contactors where the same contact arrangement and voltage rating are required.
