ABB CA4-40E Series Auxiliary Contact Block, 6A Contact Current, 690V Contact Voltage - 1SBN010140R1040


This auxiliary contact Block provides additional switching contacts to extend the signalling and control capability of contactors in industrial electrical systems. It is designed for front mounting and connects via screw terminals, enabling straightforward installation on the operator-facing side of equipment. The component suits automation and control panels where compact, accessible auxiliary contacts are required.

Features and Benefits:


• Four normally open contacts offering expanded signalling capability
• Operational current rated at 6 A for control circuit handling
• Rated insulation voltage of 690V for higher-voltage applications
• Front mounting arrangement for easy service access
• Screw Terminal connections for secure, low-resistance wiring
• Mechanical endurance of 3600 cycles to support repetitive switching

Applications


• Suitable for remote status indication of contactors in motor control centres
• Ideal for interlock circuits within factory automation systems
• Used with control relays for auxiliary logic functions
• Can be used for signalling in distribution boards and switchgear
• Used for expanding contact capacity in retrofit control upgrades

What is the normal contact configuration and how does it affect wiring?


It contains four normally open contacts, allowing parallel or sequential control wiring arrangements for multiple signalling or interlock functions.

How does the mounting location influence panel layout?


Front mounting places the Block where it can be accessed from the panel front, simplifying inspection and reducing the need to access behind-mounted components.

What Terminal type is provided and what wiring practise is recommended?


Screw terminals are fitted

use appropriately sized ferrules or fully inserted conductors and correct torque to maintain low contact resistance.

How does the device perform under frequent switching?


The Block is specified for 3600 mechanical cycles, making it suitable for applications with regular but not continuous Rapid actuation.
