ABB Auxiliary Contact, 4 Contact, 4 NC, CA4, Front, 6 A, 690V ac, 1SBN010140R1104 CA4-04M

This auxiliary contact provides a Compact, front-mounted solution for adding auxiliary switching to contactors in industrial control systems. Designed for direct front-side attachment, it supplies four normally closed instantaneous contacts and is intended for integration where a Compact footprint and secure screw terminals are required. The unit operates across a wide ambient temperature range and is suitable for conventional industrial electrical panels and control cabinets.

• Four instantaneous NC contacts offering dependable circuit isolation
• Rated operational current up to 6 A for common control circuits
• Insulation withstand up to 690V for enhanced voltage margin
• Mechanical endurance rated at 10 million cycles for long service life
• Screw-terminal connection for straightforward wiring and replacement
• Operates from −40 °C to 70 °C for broad environmental compatibility

• Suitable for retrofitting auxiliary contacts on compatible contactors in control panels
• Ideal for monitoring contactor status in motor control systems
• Used with automation racks requiring Compact four-pole signalling
• Can be used for safety interlock feedback in industrial switchgear

Conductors are secured via screw terminals compatible with flexible and solid conductors within the specified cross-section ranges, allowing ferrules where needed.

Mechanical switching capability reaches 3,600 cycles per hour electrically and up to 1,200 cycles per hour for AC-15 utilisation under the specified ratings.

It withstands short-time currents with values such as 140 A for 0.1 s and 100 A for 1 s under rated conditions.

The Terminal accepts rigid and flexible conductors from around 1 mm² up to 2.5 mm², including combinations and insulated ferrules as specified.
