Description
VSP D2 is a single-phase preventor with an adjustable unbalance threshold and selectable reset mode, verified against Minilec’s own official product page. It is also called a phase failure relay or single phasing preventer: it trips the motor starter when a phase is lost or the three phase voltages are unbalanced beyond the set level, protecting the motor from overheating.
Minilec model VSP D2 is also written as VSPD2.

Choose a single phasing preventer
A single phasing preventer (phase failure relay) switches off the motor starter when a phase is lost or the three voltages become unbalanced, before the motor overheats. Choose by supply voltage, whether you also want under/over-voltage protection, the number of output contacts and the mounting.
