This component is essential for industrial control systems requiring stable electrical performance and protection against transient voltage spikes in 120-230V AC/DC applications.

## Long description

The Phoenix Contact V3-120-230UC is a specialized plug-in module engineered for seamless integration with ECOR-3 relay sockets. This component serves as a critical protective element within industrial control systems, incorporating an integrated varistor to safeguard sensitive relay circuits against transient voltage spikes and electrical surges. Designed for versatility, it supports a wide input voltage range of 120-230V AC/DC, ensuring consistent and reliable performance in demanding electrical environments.
Advantages
The primary benefit of this module is its robust protection capability, which effectively mitigates the risk of damage to relay coils and connected control electronics caused by voltage fluctuations. Its plug-in design facilitates rapid installation and replacement, significantly reducing maintenance downtime in complex control cabinets. Furthermore, the inclusion of a varistor provides a compact, space-saving solution for surge suppression, eliminating the need for external protective circuitry while maintaining high operational standards and compliance with international safety certifications.
Suitable for
Industrial automation and control systems
Protection of relay coils in 120-230V AC/DC circuits
Electrical panels requiring surge suppression for switching components
Applications where space-saving modular protection is prioritized
When it may not be suitable
This module is specifically designed for use with compatible ECOR-3 relay sockets and may not be compatible with other relay base types or different mounting standards. It is not intended for use in high-voltage power distribution networks or applications exceeding the specified voltage tolerance range.
Key specifications
Input voltage range: 120-230V AC/DC (± 20%)
Integrated component: Varistor
Compatibility: ECOR-3 relay sockets
Certifications: UL, cUL, cULus
How to use
To install the module, ensure the power supply to the control circuit is disconnected to prevent accidental contact. Align the pins of the V3-120-230UC module with the designated slots on the ECOR-3 relay socket. Gently press the module into the socket until it is securely seated. Once installed, verify that the module is firmly attached before restoring power to the system. The module operates automatically to suppress voltage transients without requiring manual configuration.
What to consider before purchase
Verify that your existing relay socket is an ECOR-3 model
Confirm that your operating voltage falls within the 120-230V AC/DC range
Check the space availability in your control cabinet for the plug-in module
Ensure compliance with your local electrical safety standards
Usage recommendations
Always ensure that the module is fully inserted into the socket to maintain proper electrical contact and protection. Periodically inspect the module for signs of physical damage or discoloration, especially after significant electrical disturbances in the system.
