the answer is ;
using System.Collections.Generic;
using UnityEngine;

public class DW : MonoBehaviour {

public Transform DestroyedVersion;
public float magnitudeCol, radius;
private bool callOnce;

void OnCollisionEnter2D(Collision2D other)
{
	if(other.relativeVelocity.magnitude >  magnitudeCol && !callOnce)
	{
		callOnce = true;
		Destroy (gameObject);
		Instantiate (DestroyedVersion, transform.position, transform.rotation);
	}
}

}

Problem seems to be that your speed is triggering mutliple collisions. Simplest way might be to just mark that you’ve already hit something.

public float magnitudeCol, radius;

private bool canBreak = true;

 void OnCollisionEnter2D(Collision2D collision)
 {
     if(canBreak && collision.relativeVelocity.magnitude >  magnitudeCol)
     {
         canbreak = false;
         Destroy (gameObject);
         Instantiate (DestroyedVersion, transform.position, transform.rotation);
     }
 }
