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

This auxiliary contact Block provides additional switching contacts for control systems and contactors, delivering Compact front-mounted switching capability for industrial automation. It is designed to be fitted to the front of contactors where supplementary normally closed contacts are required, supporting control-circuit signalling and interlocking duties in electrical panels.

• Four normally closed contacts delivering dedicated circuit isolation
• 6A switching capacity enabling modest control-current handling
• Rated insulation voltage 690V allowing high-voltage control circuits
• Screw terminals providing secure conductor termination
• Four-pole configuration offering simultaneous multi-circuit control
• Mechanical rating of 3600 cycles ensuring predictable operational life

• Suitable for interlock control in motor starter assemblies
• Ideal for signal feedback to PLCs in automation panels
• Used with contactors to expand auxiliary contact counts
• Can be used for safety-circuit monitoring in distribution boards
• Used for pilot duty signalling in industrial control systems

Connections are MADE via screw-type terminals that permit firm tightening of conductors for reliable electrical contact in panel environments.

It is rated for pilot duty under A600 and Q600 classifications, making it appropriate for control and signalling tasks within those pilot-duty categories.

The device is specified for 3600 mechanical cycles, which defines its operational life under manual or automated actuation sequences.

The component provides four poles, enabling control of up to four independent circuits at once.

The insulation rating is 690V, which suits it to higher-voltage control installations where such dielectric strength is required.
