This Schneider Electric LV429414 undervoltage release is designed for professionals needing reliable remote opening or emergency shutdown for Compact NSX, PowerPact Multistandard, and EasyPact circuit breakers. Its key benefit is ensuring circuit protection by automatically opening the breaker when control voltage drops critically low, preventing damage. A caveat is its fixed mounting mode, requiring specific installation considerations. This device acts as a crucial safety auxiliary for power circuit breakers, off-load switches, and motor safety switches.

Its primary function is to automatically trip open the associated circuit breaker when the control voltage drops to below 35% of its nominal value, serving as a safety mechanism for remote opening or emergency shutdown.
It is designed for use with Schneider Electric Compact NSX, PowerPact Multistandard, and EasyPact CVS circuit breakers.
The response time is approximately 50 milliseconds.
No, this undervoltage release is designed for tripping the breaker upon voltage loss and does not facilitate automatic reclosing.
It has a rated voltage of 250 VDC.
This model features a fixed mounting mode, intended for permanent installation onto compatible circuit breakers.
It features screw connection terminals for electrical connections.
Verify the control voltage supply is indeed dropping below 35% of its nominal value. Check all wiring connections to the undervoltage release and the circuit breaker for security. Ensure the undervoltage release is correctly installed and compatible with the circuit breaker.
Check for loose wiring connections at the undervoltage release or control power source. Investigate potential sources of electrical noise or interference affecting the control voltage. Confirm the control voltage is stable and not fluctuating outside acceptable limits.
Ensure the control voltage is applied to the correct terminals of the undervoltage release. If the unit has been subjected to excessive voltage or physical stress, it may require replacement. Consult the circuit breaker's manual for any specific reset procedures.
Setup: The LV429414 features a fixed mounting mode, meaning it is designed to be permanently installed onto compatible Schneider Electric circuit breakers like the Compact NSX, PowerPact Multistandard, and EasyPact CVS series. Installation involves securely attaching the release unit to the designated points on the circuit breaker and connecting the control voltage wires to the screw terminals. Ensure power to the circuit breaker and control system is disconnected before beginning installation.
Compatibility: This undervoltage release is specifically designed for use with Schneider Electric Compact NSX, PowerPact Multistandard, and EasyPact CVS circuit breakers. Verify compatibility with your specific circuit breaker model before installation. It operates with a rated voltage of 250 VDC.
Care: As an electrical component, the undervoltage release requires minimal physical care. Keep the area around the installed unit clean and free from dust and debris. Regularly inspect electrical connections for tightness. Ensure the control voltage supply remains within the operational parameters to guarantee the release's functionality. No routine maintenance is typically required for the release itself, beyond ensuring the associated circuit breaker is maintained as per its guidelines.
