The ABB CAT4-11E is a front-mounted instantaneous auxiliary contact block designed for use with ABB contactors and motor starters. This versatile contact block provides one normally open (1 N.O.) and one normally closed (1 N.C.) contact configuration, allowing for flexible control circuit integration and signaling applications.

Key Features:

• Instantaneous switching action for reliable control circuit operation
• 1 normally open and 1 normally closed contact configuration
• Front-mount design for easy installation and access
• Compatible with ABB A-line contactors and motor control products
• Compact design minimizes panel space requirements
• Snap-on mounting for quick field installation without tools

Auxiliary contact blocks are essential components for building control circuits, providing status indication, interlocking sequences, and pilot circuit control. The CAT4-11E's dual contact configuration makes it ideal for applications requiring both normally open and normally closed contacts in a single compact unit.
