SE_P14x_OC

MiCOM P14x shaped phase overcurrent element (ANSI 50/51) with the four IEC 60255-151 inverse-time curves, definite time and an instantaneous high set.

When to use it

Use SE_P14x_OC when a feeder, transformer incomer or motor circuit needs a graded phase-overcurrent characteristic modelled in the PLC — for interlocking, load-shedding logic, a digital twin of a substation, or an operator-training simulator — alongside the real relay that does the tripping.

Supervised control write

SE_P14x_OC commands a real actuator. It is written to sit underneath your own interlock, permissive and protection logic — not to replace it. Commission it as you would any control block you wrote yourself.
