6. Selection Recommendations
- Voltage requirements: Confirm that the URRHH is compatible with your system’s control voltage.
- Load type: For inductive loads, use snubber circuits to prevent arcing.
- Redundancy: Pair it with redundant power supplies for critical applications.
7. Installation & Maintenance
- Wiring: Use AWG 14–16 wires for load connections and follow NEC 110.14 guidelines.
- Environmental protection: Install it in IP54-rated enclosures for dusty or wet environments.
- Testing: Regularly check the contact resistance (should be less than 50 mΩ).
