ABB CA4 Series Auxiliary Contact Block, 6A Contact Current, 690V Contact Voltage - 1SBN010140R1204 CA4-04N

This auxiliary contact Block provides additional signalling contacts for control systems and motor starters, designed for front mounting to the side of compatible devices. It is intended to augment switching assemblies with multiple normally closed contacts and integrates directly via screw terminals for straightforward field wiring.

Features and Benefits:

• Four normally closed contacts provide redundant status feedback
• Rated for 6A operational current to handle control circuits
• Insulation rating of 690V supports higher-voltage systems
• Mechanical endurance of 3600 cycles for frequent operation
• Front-side mounting enables Compact panel integration
• Screw terminals allow secure, serviceable connections

Applications

• Suitable for alarm and interlock circuits in automation panels
• Ideal for integration with contactors in motor control centres
• Used for status feedback to PLCs and control relays
• Can be used for auxiliary signalling in switchgear assemblies

How many contact poles are available and how are they configured?

There are four poles configured as normally closed contacts to provide multiple circuit-break signals or interlocks.

What electrical load can each contact reliably carry?

Each contact is specified for a continuous operational current of 6A suitable for typical control and signalling loads.

How is the unit attached and wired in a control cabinet?

The Block mounts on the front side of the main device and uses screw terminals for fastening conductors and ensuring a Durable electrical connection.

What operational life can I expect under frequent switching?

The contact Block is designed for mechanical durability rated at 3600 cycles to cover repetitive switching duties.
