48VDC UVR coils holding in for too long
(OP)
Has anyone ever dealt with DC Undervoltage Release coils taking a long time to drop out. I have never had this problem with AC coils. These should be less than 100ms but are ocassionally hold as long a 900ms. I am thinking residual magnetism, any ideas?

Is this a new issue or are your units consistently taking too long?

The point is: a reduced air gap may make a relay or solenoid "sticky".
