ABB EH04-11N is a 1NO/1NC auxiliary contact block with a 6 A conventional free-air thermal current, designed for tool-free side mounting on compatible ABB ESB..N installation contactors and EN..N installation relays.
Why Choose the ABB EH04-11N Auxiliary Contact Block?
The ABB EH04-11N is a compact 1NO/1NC auxiliary contact block designed to extend the signalling and control capabilities of compatible ABB ESB..N installation contactors and EN..N installation relays. As part of the ABB EH04..N accessory range, it provides additional contacts for status indication, interlocking and control circuit functions.
This auxiliary contact block features one normally open and one normally closed contact, providing two complementary switching functions from a single accessory. It is designed for simple tool-free attachment to the left side of compatible ABB installation contactors and relays, helping simplify panel assembly, maintenance and system expansion.
The EH04-11N has a conventional free-air thermal current of 6 A for the auxiliary circuit and supports AC-15 and DC-13 control applications. Its compact side-mounted construction and screw terminals make it a practical accessory for electrical distribution, building automation and industrial control systems.
Key Advantages
1NO + 1NC auxiliary contact configuration for flexible signalling and control.
Compatible with a wide range of ABB ESB..N contactors and EN..N installation relays.
Tool-free mounting simplifies installation and maintenance.

Reliable Auxiliary Control and Signalling
Auxiliary contact blocks such as the ABB EH04-11N provide additional low-power contacts that operate together with the associated contactor or relay. These contacts can be incorporated into control circuits for electrical interlocking, equipment status indication, feedback and sequencing without using the main power contacts.
The EH04..N range is designed for straightforward integration with ABB installation contactors and installation relays. Its tool-free side mounting allows the accessory to be clipped onto compatible devices quickly, while the 1NO/1NC configuration provides complementary contacts for flexible control circuit design.
Typical Applications
Contactor status indication and feedback circuits.
Electrical interlocking between contactors.
Building automation and lighting control systems.
Heating and load-control installations.
Electrical distribution and control panels.
Industrial automation and sequencing circuits.
