Why Choose the ABB E260CA-16-40 Latching Relay?
The ABB E260CA-16-40 is a versatile electronic latching relay with four normally open (4NO) contacts designed for reliable switching in residential, commercial and building-control installations. As part of the ABB E260CA electronic latching relay series, it combines a 16 A rated current, universal control voltage and adjustable central ON/OFF control in a compact DIN-rail device.
The E260CA-16-40 allows connected loads to be switched using momentary control signals while providing dedicated local/group and central control functions. Central commands have priority over local switching commands, enabling multiple relays and circuits to be controlled reliably from a central point regardless of their previous switching state.
With four normally open contacts, a universal 8–240 V AC/DC control supply and support for LED loads up to 200 W at 230 V, the E260CA-16-40 provides considerable installation flexibility. Its 35 mm-wide DIN-rail housing makes it suitable for multi-circuit lighting, fan, air-conditioning and building-control applications.

Flexible Multi-Circuit Latching and Centralised Control
Electronic latching relays such as the ABB E260CA-16-40 change their switching state in response to control impulses, allowing electrical loads to be operated from multiple control points without requiring continuous coil energisation. Its four normally open contacts make it particularly useful where several circuits need to be incorporated into a common control arrangement.
The adjustable central ON/OFF functionality extends this flexibility by allowing central commands to take priority over local control inputs. Combined with its universal 8–240 V AC/DC supply capability and dedicated local/group control connections, the E260CA-16-40 provides a flexible platform for lighting, ventilation and other building-service control systems.
Typical Applications
- Multi-circuit lighting control systems.
- Centralised ON/OFF building control.
- Residential and commercial electrical distribution.
- Hotels, offices and workplace installations.
- Fan and ventilation control systems.
- Air-conditioning and building-services control.
