ABB VD4 Shunt Release Coil 220V 110V 48V Closing Opening MU MO1 MC New

The ABB VD4 Shunt Release is a critical spare part for the world-renowned VD4 Vacuum Circuit Breaker. These coils are the "trigger" of the medium-voltage power grid, responsible for remote closing, opening, and undervoltage protection. Designed for precision and extreme durability, Fradwell provides the full range of genuine VD4 releases to ensure your switchgear operates safely and responds instantly to control signals.

Product Highlights

Original Precision: 100% compatible with ABB VD4 series (1VNA/1VCP series), ensuring perfect mechanical fit.
Universal Voltage Support: Available in all standard grid voltages (24V to 240V AC/DC) for global compatibility.
Instant Response: High-speed electromagnetic activation ensures circuit interruption or closure within milliseconds.
Maintenance Essential: A must-have spare part to minimize downtime in power plants and industrial substations.

Frequently Asked Questions

Q1: What is the difference between MC and MO1 coils?

A: MC is the Shunt Closing Release used to close the breaker; MO1 is the Shunt Opening Release used to trip/open it.

Q2: Can I use a DC coil on an AC circuit?

A: Many VD4 coils are dual-rated (AC/DC); however, please verify the specific voltage range on the product label.

Q3: How do I find the correct part number?

A: Check the side of your existing coil for the 1VNA or 1VCP prefix followed by a numerical code.

Q4: Is the Undervoltage Release (MU) mandatory?

A: It is optional but highly recommended to automatically trip the breaker if supply voltage drops dangerously low.

Q5: What other spares should I buy with this?

A: We recommend the "Maintenance Trio": Shunt Release, Auxiliary Contact, and Charging Motor.

Q6: What is the lead time for 110V versions?

A: Standard 110V and 220V versions are always in stock for immediate 1-3 day shipping.
