## Summary description

Bistable relay FF BIS-408i is a latching electromagnetic switch with one normally open (1 NO) contact rated 16 A at 230 V AC. Designed for maintaining its contact state without continuous coil power, it suits lighting circuits, motor controls and building automation tasks where power-efficient switching and state retention are required.

## Long description

Bistable Relay FF BIS-408i — 1 NO, 16A, 230V AC is a latching electromagnetic switch with one normally open contact. It holds its contact position after being set or reset, so no continuous coil power is required to maintain the last state. The relay is rated for switching resistive and inductive loads up to 16 A at 230 V AC and is intended for installation in control panels and DIN-rail systems within lighting, motor control and building automation circuits.
Advantages
The bistable design reduces standby energy consumption because the relay retains its state mechanically after operation. A single normally open contact provides a simple switching function for loads up to 16 A at mains voltage. The compact construction is suitable for mounting in enclosed switchgear or distribution boards, and the electromagnetic latch ensures reliable state retention even after power interruptions. The relay’s specification supports common control tasks in residential and commercial electrical installations.
Suitable for
 Lighting circuits where state retention is required (e.g., stairway or corridor lighting)
 Motor start/stop control for small motors and actuators within rated current
 Building automation tasks that require power-efficient switching and memory of last state
 Control panels and DIN-rail installations in residential or commercial electrical systems
Key specifications
 Contact configuration: 1 normally open (1 NO)
 Contact rating: 16 A at 230 V AC
 Switch type: bistable (latching) electromagnetic relay
 State retention: mechanical latch retains contact position without continuous coil power
 Mounting: DIN-rail / control panel compatible compact housing
 Typical applications: lighting, motor control, building automation
How to use
Install the relay in accordance with local electrical codes and the panel layout, ensuring proper DIN-rail mounting and secure terminal connections. Connect the supply and load conductors to the appropriate contact terminals and wire the control inputs that set and reset the latch according to your control circuit design. Actuate the setting coil to close the normally open contact and the resetting coil to open it; after actuation the relay will maintain the selected state without further coil power. Verify correct wiring and insulation before energizing the circuit, and perform functional tests at no-load or under controlled conditions.
Usage recommendations
Use the relay within its rated current and voltage limits and avoid frequent switching at maximum load to prolong contact life. Incorporate appropriate surge suppression or snubber circuits when switching inductive loads, and follow recommended wiring practices and protective devices for safe operation.
