ABB CA5-31ERT Series Auxiliary Contact Block, 4A Contact Current, 690V Contact Voltage - 1SBN010042R1031

This auxiliary contact Block provides additional switching contacts to complement control devices in electrical systems. Designed for front mounting, it integrates with control panels and contactor assemblies to expand contact configurations without altering primary devices. The unit supports mixed normally open and normally closed arrangements for auxiliary signalling and interlock functions.

Features and Benefits:

• 4P configuration delivers four contact poles for expanded control
• 3NO/1NC arrangement enables combined signalling and safety interlocks
• Screw Terminal connection simplifies secure wiring terminations
• Rated insulation voltage 690V allows use in high-voltage control circuits
• Contact current 4A supports moderate auxiliary load switching
• Operational current Ie 2A limits continuous pilot duty switching to specified level

Applications

• Suitable for remote signalling in industrial contactor panels
• Ideal for interlock arrangements in motor control systems
• Used with PLC inputs for status feedback of power devices
• Can be used for auxiliary switching in automation cabinets
• Suitable for replacing worn auxiliary contacts in existing assemblies

What mounting method is required for installation?

It is designed for front mounting so it attaches to the face of compatible control devices to align contacts and maintain panel accessibility.

What Terminal style is provided for wiring?

Connections are MADE via screw terminals to ensure firm conductor retention and straightforward field wiring.

How does the contact arrangement support control logic?

The mixed configuration of three normally open and one normally closed contact permits combined signalling and fail-safe circuits within a Compact auxiliary block.

What duty ratings relate to pilot applications?

The contact block’s operational current is specified at 2A, with switching capacity for contact current up to 4A, aligning it with typical pilot duty requirements.

Which electrical insulation level does it meet for application planning?

The unit is specified with a rated insulation voltage of 690V, informing selection for higher-voltage control environments.
