Why Choose the ABB HK40011-R Auxiliary Switch?
The ABB HK40011-R is a compact auxiliary switch designed for right-side mounting on compatible protective and switching devices within the ABB SMISSLINE TP plug-in distribution system. Featuring one normally open (1NO) and one normally closed (1NC) contact, it provides dependable remote indication of the operating position of the associated device.
As part of the ABB SMISSLINE TP accessory range, the HK40011-R is designed for right-side installation on compatible S400 miniature circuit breakers, F402/F404 residual current circuit breakers and IS404 switch disconnectors. Its plug-in architecture and connection to the LA/LB auxiliary busbars support efficient integration into modular low-voltage distribution assemblies.
The HK40011-R has an AC-15 operational current rating of 2 A at 230 V AC and occupies only 0.5 module. Its compact construction, 1NO + 1NC contact arrangement and dedicated right-side mounting make it suitable for status indication, interlocking and control-system interfaces in commercial and industrial electrical installations.

Reliable Auxiliary Status Signalling
Auxiliary switches provide additional electrical contacts that follow the operating state of a protective or switching device. The ABB HK40011-R provides both normally open and normally closed contacts, enabling status indication, electrical interlocking and control functions without changing the primary circuit of the associated device.
Its right-side mounting arrangement and SMISSLINE TP compatibility allow the auxiliary switch to integrate neatly into modular distribution assemblies. The compact half-module format helps preserve valuable panel space while providing dependable auxiliary signalling for monitoring and automation systems.
