2CDE110000R0501 ABB E232-230 Staircase Time Switch 1–7 Minutes 230 V AC

Why Choose the ABB E232-230 Staircase Time Switch?

The ABB E232-230 is a compact electromechanical staircase lighting time-delay switch designed to switch lighting off automatically after a preset period. Operating from a 230 V AC, 50 Hz supply, it provides a practical solution for controlling lighting in stairways, corridors, entrance areas, basements and other shared building spaces.

The adjustable timing range extends from 1 to 7 minutes, with adjustment in 15-second increments. Its synchronous-motor-driven electromechanical timer provides dependable operation regardless of mounting position, while the device can be retriggered after approximately 30 seconds when used in its intended staircase-lighting circuit.

With a 16 A resistive load rating and a width of only 17.5 mm, the E232-230 delivers useful lighting-control capability in a single DIN module. It is designed for pushbutton control and supports glow-lamp current up to 150 mA, making it particularly suitable for multi-storey residential and commercial buildings.

Key Advantages

• Automatically switches lighting off after an adjustable time delay.
• 1–7 minute timing range for flexible staircase and corridor lighting control.

Reliable Automatic Staircase and Corridor Lighting Control

Staircase time switches allow lighting to be activated temporarily from conveniently positioned pushbuttons and then switched off automatically after the selected interval. The ABB E232-230 reduces the need for users to switch lighting off manually, helping avoid unnecessary continuous operation in communal building areas.

Its adjustable 1–7 minute timing period allows the illumination duration to be matched to the application, while the electromechanical synchronous-motor mechanism provides straightforward and dependable time-delay control. Compatibility with illuminated pushbuttons further supports installations across multiple floors or access points.

Typical Applications

• Staircase lighting in residential buildings.
• Apartment and multi-storey communal areas.
• Corridors and passageways.
• Basement and cellar lighting.
• Entrance halls and lobbies.
• Commercial building circulation areas.
• Timed lighting circuits controlled by multiple pushbuttons.
