Why Choose the ABB SK40002-L Auxiliary Signal Contact?
The ABB SK40002-L is a left-side signal contact with two normally closed (2NC) contacts designed for compatible devices in the ABB SMISSLINE TP plug-in system. Supplied under ABB order code 2CCF201164R0001, it provides dedicated signalling contacts for integrating protective-device status into external monitoring, indication and control circuits.
Designed for left-side mounting, the SK40002-L is specified for compatible ABB S400 miniature circuit breakers and FS401/FS403 RCBOs. The two normally closed contacts provide a defined auxiliary signalling arrangement that can be incorporated into building-management, alarm and industrial control systems.
The SK40002-L occupies only 0.5 module, helping minimise the additional panel space required for signalling functionality. Each unit weighs approximately 40 g, and the product is supplied in a packaging unit of 10 pieces for professional distribution-board and panel-building applications.

Signal Monitoring for SMISSLINE TP
ABB SMISSLINE TP signal contacts allow compatible protective devices to be integrated with external status-monitoring and signalling circuits. The SK40002-L mounts on the left side of the associated device and provides two normally closed contacts, giving installers additional electrical contacts for remote indication and control functions.
This signalling capability is useful in distribution boards where the status of protective equipment needs to be communicated to alarm circuits, building-management systems, control equipment or industrial automation systems. Its compact 0.5-module construction provides this additional functionality while using minimal DIN-rail space.
Typical Applications
- ABB SMISSLINE TP modular distribution systems.
- Signal monitoring of compatible S400 miniature circuit breakers.
- Status signalling from compatible FS401 RCBOs.
- Status signalling from compatible FS403 RCBOs.
- Building-management, alarm and electrical monitoring circuits.
- Industrial control and distribution panels requiring remote protective-device signalling.
