DIN-rail impulse relay FF BIS-413 230V AC 16A for TH35 rail mounting

FF BIS-413 is a DIN-rail impulse relay designed for installation on standard TH35 rails. Operating from a 230V AC supply, this device provides a single-channel changeover for momentary input control, enabling toggling of lighting and low-power circuits. Its compact design fits typical electrical distribution boards and is intended for residential and commercial applications where centralized or multi-point switching is required.

Advantages

The impulse relay allows control of a load with short pulse inputs, reducing the need for continuous power on control circuits and enabling multiple push-button locations to operate the same output. Its 16A switching capacity supports a range of lighting loads and small appliances while conserving space inside distribution enclosures thanks to its DIN-rail form factor. The relay’s design simplifies wiring for centralized lighting control and helps integrate momentary switches into existing installations.

Suitable for

• Centralized or multi-location lighting control in homes and offices
• Switching of small appliances and lighting circuits up to 16A
• Retrofit installations in TH35 rail distribution boards
• Applications where momentary push-button control is preferred

Key specifications

• Supply voltage: 230V AC
• Switching capacity: 16A (AC)
• Mounting: DIN-rail TH35
• Control type: impulse (momentary input) toggle
• Channels: single channel changeover output

How to use

Mount the impulse relay on a standard TH35 DIN rail inside the electrical distribution board and connect the supply and load according to wiring standards and local regulations. Wire one or more momentary push-buttons to the relay’s control input; each short pulse will toggle the output state. Verify that the total connected load does not exceed the rated 16A switching capacity. Follow safe isolation procedures when installing or servicing the device.

Usage recommendations

For reliable operation, use the relay within its rated voltage and current limits and install it in a dry, ventilated enclosure. Combine with rated wiring and protective devices (breakers, fuses) appropriate for the circuit. When integrating multiple push-buttons, use low-voltage wiring runs or appropriate protection to prevent interference and ensure consistent pulse signaling.
