Finished in a distinctive blue colour, this device features a potential-free contact configuration suitable for various electrical installation and automation tasks in residential and commercial environments, ensuring reliable circuit control.

## Long description

The Eltako ER12DX-UC electrical relay blue with 16 A current capacity and potential-free contact is a reliable modular device engineered for efficient circuit control in residential and commercial electrical installations. Designed for DIN rail mounting, this blue switching relay features a 2-pole configuration and supports a maximum current capacity of 16 amperes at 250 volts alternating current. It provides continuous operation capability and features a clear switch position indicator for convenient monitoring during everyday use.
Advantages
This electrical relay offers a universal control voltage range that accommodates both alternating current and direct current sources from 12 to 230 volts, ensuring high flexibility across different installation setups. The inclusion of a potential-free contact configuration allows for versatile circuit control while maintaining galvanic isolation between the control circuit and the switched load. Its compact modular design fits standard DIN rails seamlessly, saving valuable space in distribution boards and electrical enclosures.
Suitable for
Switching electrical loads up to 16 A in residential and commercial buildings
Electrical automation tasks requiring reliable potential-free contact switching
DIN rail mounting inside standard distribution boards and control panels
Applications requiring universal control voltage compatibility from 12 to 230V AC or DC
When it may not be suitable
This device is not designed to switch electrical loads that exceed the specified 16 A current capacity or 250V AC ratings. It is also unsuitable for environments that require specialized waterproof or heavy-duty outdoor enclosures without additional protective housing.
Key specifications
Current capacity: 16 A
Voltage rating: 250V AC
Contacts: 2 normally open (NO) potential-free contacts
Mounting type: DIN 60715 TH35 rail mounting
Width: 1 module (18 mm), depth: 55 mm
Control voltage: Universal 12 to 230V AC (50-60Hz) and 12 to 230V DC
Operation time: 100% duty cycle
How to use
Installation should be performed by a qualified electrician in accordance with local electrical safety regulations and guidelines. Mount the relay securely onto a standard DIN rail inside an appropriate enclosure or distribution board. Connect the universal control voltage wires to the designated terminals and wire the load to the potential-free contacts observing the maximum current and voltage limits. Verify all connections before restoring power to the circuit and utilize the manual control and switch position indicator to test functionality.
What to consider before purchase
Verify that your electrical load requirements do not exceed the 16 A current limit
Check that your control voltage falls within the universal 12 to 230V AC or DC range
Ensure there is sufficient space on your DIN rail within the distribution board
Confirm whether professional electrical installation is required for your specific setup
Always disconnect the main power supply before installing, inspecting, or servicing the electrical relay to prevent electrical shock or equipment damage.
