Eltako Rotary switch 1P Blue 230 V 16 A

The Eltako rotary switch is a modular monitoring relay designed for electrical installations to monitor 230 V AC voltage and phase conditions in residential and commercial systems. Featuring a 1-pole configuration and a blue housing, this device operates at a 230 V input voltage and supports a rated current of 16 A. It mounts on standard DIN rails and provides reliable circuit control and voltage supervision.

Advantages

This rotary switch offers precise monitoring of phase conductors and rotating fields, ensuring proper electrical system operation. With low standby loss and adjustable operate and release delays, it delivers efficient and customizable performance. The inclusion of clear LED indicators allows for quick status assessment and fault identification during operation.

Suitable for

• Monitoring 230 V AC voltage between one to three phase conductors and neutral
• Checking clockwise rotating fields in switch positions for multi-phase systems
• Electrical installations in residential and commercial buildings requiring phase supervision

When it may not be suitable

This device is not designed for direct high-power load switching beyond its specified electrical ratings. It may also not be suitable for applications requiring non-standard operating voltages outside the defined supply voltage range.

Key specifications

• 1-pole configuration with 1 potential-free CO contact
• Input voltage of 230 V AC
• Rated current of 16 A
• Modular device width of 18 mm and depth of 58 mm
• Designed for DIN rail mounting
• Adjustable release delay from 0.1 to 8 seconds

How to use

Mount the modular device onto a standard DIN rail within a suitable electrical enclosure. Connect the supply voltage and phase conductors according to the technical requirements. Use the front rotary switches to select the number of monitored phase conductors, configure the voltage thresholds, and set the desired release delay time. Observe the LED indicators to verify correct operation and system status.

What to consider before purchase

• Verify that the supply voltage matches the 230 V AC specification
• Ensure compatibility with your DIN rail enclosure space, keeping the 18 mm width in mind
• Confirm that the technical parameters meet your specific phase monitoring requirements

Installation should be performed by qualified electrical personnel in accordance with local regulations and safety standards. Regularly check the indicator LEDs to ensure the monitored circuits are functioning correctly.
