FF stairway automatic switch AS-212 230V 16A for DIN rail 1-module IP40

FF AS-212 is a stairway automatic switch designed for DIN-rail mounting in distribution boards. The device operates from a 230 V supply and handles loads up to 16 A while occupying a single module width. With IP40 protection, the switch provides timed automatic control of lighting circuits in stairwells, corridors and shared indoor spaces, allowing lights to turn off automatically after a set interval to reduce energy consumption and ensure convenient hands-free operation.

Advantages

The AS-212 offers compact DIN-rail mounting and occupies only one module, making it suitable for dense installation environments. It supports standard 230 V mains and a 16 A switching capacity adequate for typical lighting circuits. The timed switching function simplifies control of common-area lighting without requiring additional sensors, and the IP40 rating protects the device from solid objects while allowing installation inside distribution enclosures.

Suitable for

• Stairwell and corridor lighting in residential buildings
• Common-area lighting in apartment blocks and offices
• Temporary or pulse-controlled lighting circuits where timed shutoff is needed

Key specifications

• Supply voltage: 230 V AC
• Rated switching current: 16 A
• Module width: 1 DIN module
• Protection degree: IP40 (suitable for installation inside distribution cabinets)
• Function: timed automatic switch for lighting circuits

How to use

Mount the unit on a standard DIN rail inside a protected distribution enclosure and wire the supply and load according to local electrical regulations and the installation diagram supplied with the device. After power-up, the switch can be triggered by a push-button or external control signal to start a timing cycle; the connected lighting will remain on for the preset interval and then switch off automatically. Adjustments to timing and control inputs should be performed by a qualified electrician following the manufacturer's instructions.

Usage recommendations

Install the AS-212 inside a locked distribution cabinet to maintain IP40 protection level and prevent unauthorized access. Ensure total connected load does not exceed the 16 A rating and use appropriate circuit protection. For reliable operation in communal areas, combine the timed switch with clearly marked push-buttons and periodic maintenance checks.
