## Summary description

Bistable (latching) single-pole relay FF BIS-411M-LED rated 16 A at 230 V AC with integrated memory function and specified inrush capability 160 A for 20 ms. Designed for switching circuits where state retention after power loss or pulse control is needed. Suitable for lighting, automation and control panels requiring low standby consumption and reliable mechanical latching.

## Long description

Bistable Relay 1P 16A 230V AC with Memory and Inrush 160A/20ms FF BIS-411M-LED is a single-pole latching relay designed for applications that require state retention after power loss and low standby consumption. The device switches AC loads up to 16 A at 230 V and incorporates an integrated memory mechanism that keeps the contact position without continuous coil power. The relay also features a specified inrush capability of 160 A for 20 ms, allowing it to handle short high-start currents from loads such as certain lamp types or capacitive inputs.
Advantages
The bistable design reduces energy consumption by maintaining contact state without continuous coil excitation and improves safety in systems where the last known state must be preserved. The relay’s 16 A switching rating and 160 A/20 ms inrush rating provide reliable operation with inductive and high-start-current loads. Compact single-pole construction simplifies integration into control panels and lighting circuits, while the memory function supports pulse control schemes and reduces wiring complexity for latching operations.
Suitable for
 Lighting control circuits including LED and some discharge lamps with high inrush currents
 Building automation and smart control panels requiring retained contact state
 Pulse-operated switching systems where momentary control signals change relay state
 Circuits where low standby consumption and mechanical latching are desired
Key specifications
 Contact form: single-pole (1P) latching relay
 Rated switching current: 16 A at 230 V AC
 Inrush capability: 160 A for 20 ms
 Memory: mechanical latching (state retention without continuous coil power)
 Intended use: AC switching for lighting and control circuits
 Low standby power consumption due to bistable operation
How to use
Install the relay in accordance with applicable electrical standards and mounting guidelines for control panels or DIN-rail enclosures if relevant. Wire the line and load conductors to the relay contacts and connect the control pulse input according to the system’s control logic. Use momentary control pulses to toggle the relay state or apply the designated set/reset control signals when provided; once toggled, the relay will retain its contact position without continuous coil current. Verify correct polarity and grounding of the control and load circuits before switching live power. Test operation with the expected loads to ensure the inrush capability meets the application’s startup currents.
Usage recommendations
For reliable long-term operation, pair the relay with appropriate surge protection and inrush-limiting measures when switching loads with very high startup currents. When used with LED or electronic drivers, confirm compatibility with the 160 A/20 ms inrush rating and perform real-world testing to avoid premature contact wear. Follow manufacturer installation instructions and local electrical codes for best results.
