Why Choose the ABB E296CP Compensator?
The ABB E296CP, type designation E296-CP, is a compact compensator module designed as an accessory for ABB E290 electromechanical latching relays. Part of the ABB System pro M compact command and signalling range, it provides a purpose-designed solution for applications where compensation is required in E290 relay control circuits.
The E296-CP is particularly useful in installations with illuminated push-buttons, where leakage current through the push-button lamps can otherwise interfere with reliable operation of the latching relay. By providing compensation within the control circuit, the module helps maintain dependable switching behaviour when illuminated control devices are used.
Designed for DIN-rail mounting, the E296-CP has a compact width of only 18 mm and a rated voltage of 250 V AC at 50 Hz. Its modular construction allows straightforward integration alongside compatible E290 latching relays in residential, commercial, public-building and industrial control panels.

Reliable Compensation for Latching Relay Control Circuits
Electromechanical latching relays such as ABB's E290 range change their contact state each time an appropriate impulse is applied to the coil, making them particularly useful for controlling lighting from multiple push-button locations. In circuits using illuminated push-buttons, the small current flowing through the indicator lamps can create unwanted effects in the relay control circuit.
The ABB E296-CP compensator is designed for use with E290 latching relays to compensate for this effect and support dependable switching behaviour. Its compact one-module DIN-rail construction makes it easy to incorporate into existing E290-based control arrangements without unnecessarily increasing panel space requirements.

- Lighting control circuits using illuminated push-buttons.
- Multi-point lighting control in residential buildings.
- Commercial and public-building lighting systems.
- Factory and industrial lighting control panels.
- DIN-rail-mounted command and signalling systems.
