Why Choose the ABB E260CA-16-20 Electronic Latching Relay?
The ABB E260CA-16-20 is an electronic latching relay with two normally open (2NO) contacts, designed for reliable impulse-controlled switching in lighting, building automation and electrical control systems. Rated at 16 A, it combines two switching contacts with quiet electronic operation in a compact DIN rail housing.
A key feature of the E260CA version is its adjustable central ON/OFF control. In addition to local impulse switching, central inputs allow the relay to be commanded to a defined ON or OFF state, making it particularly useful where groups of lighting or other loads require both local control and overriding central operation.
The E260CA-16-20 operates with a universal 8–240 V AC/DC control voltage, allowing the same relay to be integrated into a wide variety of control-voltage systems. Its 2NO contact configuration, 18 mm one-module width and 2.4 W power loss provide substantial switching functionality while conserving DIN rail space.
Key Advantages
- Two normally open (2NO) contacts provide dual switching from one latching relay.
- 16 A rated current supports lighting and general control applications.
- Universal 8–240 V AC/DC control voltage provides excellent installation flexibility.
- Integrated central ON/OFF control supports coordinated operation of multiple relays.
- Adjustable central-control function allows the switching behaviour to be configured for the application.
- Central commands can establish a defined switching state independently of the previous local state.
- Quiet electronic operation makes the E260 range suitable for residential, commercial and workplace environments.
- Compact 18 mm width occupies only one standard DIN module.

Flexible Dual-Contact Latching Control
The ABB E260CA-16-20 changes the state of its two normally open output contacts in response to control impulses and retains the selected state until another valid command is received. This latching principle is particularly useful for lighting circuits operated from multiple pushbuttons because continuous coil energisation is not required to maintain the switched state.
The adjustable central ON/OFF function extends this capability by allowing a central command to place the relay into a defined switching state while retaining local control functionality. Combined with the universal 8–240 V AC/DC control input, quiet electronic operation and two 16 A normally open contacts, the E260CA-16-20 provides a versatile solution for residential, commercial and industrial control systems.
Typical Applications
- Lighting circuits controlled from multiple pushbuttons.
- Centralised building lighting control.
- Residential and commercial electrical installations.
- Building automation systems.
- Fan and ventilation control circuits.
- Air-conditioning control applications.
- Electrical distribution boards.
- DIN rail automation systems requiring two normally open switching contacts.
