Why Choose the ABB E299-11 Auxiliary Contact?
The ABB E299-11 is a compact auxiliary contact with 1NO and 1NC contacts designed for use with compatible ABB latching relays and installation relays. It provides separate signalling of the current operating state of the associated main module, making it useful for status monitoring and control applications.
Featuring one normally open and one normally closed auxiliary contact, the E299-11 provides complementary switching outputs for indication, signalling and interlocking circuits. Each contact supports a maximum current of 5 A, while the device has a rated voltage of 250 V AC.
The E299-11 is a snap-on additional device that attaches to the right-hand side of a compatible main module. Its DIN rail-compatible modular construction makes it suitable for distribution boards and control panels where reliable external indication of relay switching status is required.

Reliable Relay Status Signalling
Auxiliary contacts provide separate electrical outputs that follow the switching state of a primary relay without becoming part of the main load circuit. The ABB E299-11 uses one normally open and one normally closed contact to provide complementary signals that can be used for indication, monitoring, feedback or interlocking functions.
When combined with a compatible ABB latching or installation relay, the E299-11 can externally indicate the operating state of the main contacts. This makes it particularly useful in lighting control, building automation and distribution systems where relay status needs to be displayed or passed to another control circuit.
Typical Applications
- ABB latching relay auxiliary signalling.
- Installation relay status indication.
- ON/OFF status feedback circuits.
- Lighting control and building automation systems.
- Electrical distribution boards and switchboards.
- Industrial control and interlocking circuits.
