Staircase Timer Switch ORNO OR-CR-230 16A, 1 Pole, Adjustable Delay 0.5–20 min

The Staircase Timer Switch ORNO OR-CR-230 is a DIN-rail mount timing relay designed to control lighting circuits with a rated current of 16 A. It provides a single pole changeover contact and an adjustable time delay from 0.5 to 20 minutes, allowing automatic shut-off of stairwell, corridor or common-area lighting. The compact module fits standard distribution enclosures and integrates into existing lighting installations for timed switching and basic sequence control.

Advantages

This timing relay offers precise, adjustable delay settings to match room usage patterns and save energy by preventing lights from being left on. The 16 A rated current supports typical lighting loads, and the single pole contact simplifies wiring in one-circuit installations. DIN-rail mounting ensures secure installation in distribution boards and cabinets, while the mechanical timer control provides user-friendly adjustment without the need for specialized tools.

Suitable for

• Stairwell and corridor lighting in residential buildings
• Common-area and utility room lighting in apartment blocks
• Timed control of single lighting circuits in small commercial premises
• Retrofit into existing DIN-rail distribution boards for automatic shut-off

Key specifications

• Rated switching current: 16 A
• Contact configuration: single pole changeover (1-pole)
• Adjustable time delay range: 0.5 to 20 minutes
• Mounting type: DIN-rail module for standard distribution enclosures
• Function: timed automatic turn-off for lighting circuits

How to use

Install the module on a standard DIN-rail inside the distribution board and connect the live, neutral and switched live conductors according to local wiring regulations and the product wiring diagram. Set the desired delay time using the front-mounted adjustment control between 0.5 and 20 minutes. Trigger the timer via a pushbutton or control switch; the relay will energize the lighting circuit for the selected period and then automatically switch off. For safe operation, ensure the total connected load does not exceed the rated 16 A and isolate power before making connections.

Usage recommendations

Use with compliant wiring and protective devices; where multiple circuits or higher loads are present, select appropriate distribution protection and consider using multiple relays or a unit with a higher current rating. Periodically check connections and the timer adjustment to maintain reliable operation.
