ABB Auxiliary Contact, 1 Contact, 1 NC, S2C, Bottom, 2CDS200970R0031

This auxiliary contact is a bottom-fitting, single normally closed contact designed to provide signalling and interlock functions within modular low-voltage assemblies. It is intended for integration with compatible miniature circuit-breakers and residual current devices in industrial electrical panels, delivering a Compact switching Interface for control and monitoring tasks.

• 1NC contact offers fail-safe signalling for fault detection
• Bottom mount enables neat DIN-rail accessory installation
• Power loss up to 0.5 W minimises heat in crowded panels
• Conforms to RoHS and REACH supporting regulatory needs
• Compact 17.4mm width conserves rail space

• Suitable for monitoring trips on miniature circuit-breakers
• Used with residual current devices for status feedback
• Ideal for auxiliary signalling in distribution boards
• Can be used for interlocking in automation control panels

It is compatible with a range of S200-family breakers and selected S300 and related modular protection devices to provide contact state signalling to remote monitoring systems.

The single normally closed contact changes state on actuation, allowing designers to detect device operation by monitoring a break in the circuit for alarm or control sequences.

Units are supplied as single pieces with a net mass of 0.008 kg and a gross package weight of 0.012 kg for handling and logistics calculations.

It is listed under auxiliary device categories and carries CN8 and UNSPSC codes for sourcing, with product identifiers for regional E-number registration.
