Why Choose the ABB E260CA-16-10 Electronic Latching Relay?
The ABB E260CA-16-10 is an electronic latching relay with one normally open (1NO) contact, designed for reliable switching in lighting, building-control and electrical automation applications. Rated at 16 A, it combines electronic impulse switching with a mechanically simple DIN rail installation and provides quiet operation compared with conventional electromechanical impulse relays.
A key feature of the E260CA version is its adjustable central ON/OFF control. Central commands take priority over local switching commands, allowing multiple relays to be switched reliably to a defined ON or OFF state regardless of their previous switching position. The central-control behaviour can be adjusted to suit the installation requirements.
The relay uses a wide 8–240 V AC/DC universal control voltage, allowing one device to cover a broad range of control systems. Its single 1NO output contact is rated at 16 A, while the compact 18 mm housing occupies only one standard DIN module.
Key Advantages
- 16 A electronic latching relay for lighting and control applications.
- Single normally open (1NO) output contact.
- Universal 8–240 V AC/DC control voltage simplifies product selection.

- Adjustable central-control function provides additional installation flexibility.
- Central commands have priority over local switching commands.
- Electronic design provides quiet operation and eliminates conventional relay-coil humming.
- Compact 18 mm width requires only one DIN module.

Flexible Local and Central Switching Control
The ABB E260CA-16-10 changes the state of its output relay in response to local control impulses while retaining that state until another valid command is received. Its central-control inputs provide defined ON and OFF commands that take priority over local operation, allowing groups of relays to be brought reliably into the same switching state from a central control point.
The E260CA version adds adjustable central-control behaviour, including selectable command delays of 1, 2 or 3 s. Combined with its universal 8–240 V AC/DC control voltage and integrated status LED, this makes the relay suitable for flexible lighting and building-control systems where both local pushbutton operation and overriding central commands are required.
Typical Applications
- Lighting circuits controlled from multiple pushbuttons.
- Centralised building lighting control.
- Commercial and residential electrical installations.
- Building automation systems.
- Fan and ventilation control circuits.
- Air-conditioning control applications.
- Electrical distribution boards.
- DIN rail automation and control assemblies.
