Why Choose the ABB E299-20 Auxiliary Contact?
The ABB E299-20 is a compact auxiliary contact module with two normally open (2NO) contacts designed for use with compatible ABB latching and installation relays. It provides additional signalling contacts that can be used to indicate the operating state of the associated relay within electrical distribution, lighting-control and automation systems.
Rated at 5 A and 250 V AC, the E299-20 incorporates two normally open auxiliary contacts in a narrow modular housing. The contacts can provide individual status signalling from the main relay, making the module useful where relay state needs to be communicated to monitoring, indication or secondary control circuits.
At only 9 mm wide, the E299-20 adds two auxiliary contacts while requiring minimal additional DIN rail space. Its low 0.10 W power loss and purpose-designed compatibility with ABB latching and installation relays make it a practical accessory for expanding modular control installations.
Key Advantages
- Adds two normally open (2NO) auxiliary contacts to compatible relay installations.
- 5 A rated current supports signalling and auxiliary control duties.
- 250 V AC rated voltage suits common low-voltage AC control systems.
- Allows the operating state of the associated relay to be signalled to secondary circuits.
- Compact 9 mm width conserves valuable DIN rail space.
- Low 0.10 W power loss.
- Suitable for compatible ABB latching and installation relays.
- DIN rail format supports organised modular distribution and control assemblies.

Reliable Auxiliary Status Signalling
The ABB E299-20 provides two normally open auxiliary contacts that can be used to communicate the operating state of a compatible latching or installation relay to other parts of an electrical system. This allows relay operation to be incorporated into indication, monitoring or secondary control functions without using the main load contacts for signalling duties.
With a 5 A contact rating and a width of only 9 mm, the E299-20 provides useful auxiliary switching capability while preserving DIN rail space. Its two NO contacts are particularly useful where two separate status or control circuits need to respond when the associated relay reaches its active operating state.
Typical Applications
- ABB latching relay auxiliary signalling.
- ABB installation relay auxiliary signalling.
- Relay operating-state indication.
- Lighting-control systems.
- Building automation installations.
- Electrical distribution boards.
- Industrial control and monitoring circuits.
- DIN rail relay and automation assemblies.
