Why Choose the ABB SK40020-L Auxiliary Signal Contact?
The ABB SK40020-L is a compact left-side auxiliary signal contact with two normally open (2NO) contacts designed for compatible devices in the ABB SMISSLINE TP plug-in system. It provides remote electrical signalling of a protective-device trip, enabling fault conditions to be communicated to indication, monitoring or control circuits.
Unlike a conventional auxiliary contact that follows the manual ON/OFF position of the associated device, the SK40020-L is a signal contact intended to indicate automatic tripping. This makes it particularly useful in distribution systems where operators or automation equipment need to distinguish a protective trip from normal manual switching.
The SK40020-L is designed for left-side mounting and provides two normally open contacts. Its compact modular construction allows signalling functionality to be added to compatible SMISSLINE TP protective devices while maintaining an organised, space-efficient panel installation.

Reliable Remote Trip Signalling for SMISSLINE TP
Signal contacts allow the operating state of electrical protection equipment to be communicated beyond the distribution board. When a compatible protective device trips, the ABB SK40020-L can provide a corresponding electrical signal for use by warning lamps, alarms, control relays, building management systems or industrial automation equipment.
This signalling capability helps maintenance personnel and control systems identify protective-device operation without relying solely on visual inspection. The two normally open contacts also provide flexibility where the trip indication needs to be incorporated into more than one compatible signalling or control circuit.
Typical Applications
- ABB SMISSLINE TP plug-in distribution systems.
- Remote indication of protective-device trips.
- Electrical fault and alarm signalling circuits.
- Building management system status inputs.
- Industrial automation and monitoring systems.
- Commercial and industrial electrical distribution panels.

Frequently Asked Questions
What is the ABB SK40020-L used for?
The SK40020-L is an auxiliary signal contact used to provide remote electrical indication when a compatible ABB SMISSLINE TP protective device trips.
What contact configuration does the SK40020-L have?
The SK40020-L provides two normally open (2NO) contacts.
Which side does the ABB SK40020-L mount on?
The SK40020-L is specifically designed for left-side mounting on compatible SMISSLINE TP devices.
What is the difference between a signal contact and an auxiliary switch?
A signal contact is primarily used to indicate a protective trip or fault condition, while an auxiliary switch typically follows the switching position of the associated device for general status indication.
What is the ABB order code for the SK40020-L?
The ABB order code for the SK40020-L auxiliary signal contact is 2CCF201162R0001.
