ABB S800 Series Auxiliary Contact, 60°C Maximum Operating Temperature, Side Mounting Mount Type - 2CCS800900R0011


This auxiliary contact provides auxiliary signalling for control circuits in automated and electrical systems, configured to switch two independent circuits with both normally closed and normally open contacts. It is designed for side mounting on DIN rails and intended for integration alongside primary switching devices in industrial installations, operating across a moderate ambient temperature range.

Features & Benefits


• 2NC2NO contact arrangement enables separate signalling circuits
• DPDT configuration permits simultaneous dual-circuit changeover
• Side-mount DIN rail design simplifies panel installation
• Operational current rated at 0A prevents load switching misuse
• Maximum operating temperature 60°C supports warm electrical cabinets
• Minimum operating temperature -25°C allows cold-environment use

Applications


• Suitable for monitoring contactors in motor control panels
• Ideal for status feedback in PLC-connected control cabinets
• Used with auxiliary relays to expand signalling capacity
• Can be used for interlocking circuits in automation rigs
• Used for retrofit of side-mounted DIN rail assemblies

How does the device Interface with existing control equipment?


Terminals provide potential-free switching between two independent circuits, enabling direct connection to input modules and relay coils without altering primary power paths.

What mounting considerations should I follow for reliable operation?


Install on a standard DIN rail with side-mount orientation

ensure adequate ventilation to maintain ambient temperature between -25°C and 60°C.

Can it carry load currents for actuators or motors?


No, the operational current specification is 0A, indicating it is intended solely for signalling and not for switching powered loads.

What contact switching behaviour can be expected during maintenance operations?


The DPDT arrangement offers simultaneous changeover across two poles, allowing isolated testing of control logic while preserving separate NO and NC signalling paths.

Note

These contacts can not be used with type ESB20 installation contactors, only higher types e.g. ESB24
