| Description | Voltage Monitor Relay; Over/Undervoltage; 240V AC; 0.5 s fixed; SPDT |
| Datasheet | Download Datasheet |
The Macromatic VMP240A is a voltage monitor relay with SPDT output and rated 10 A at 240 V AC, 7 A at 30 V DC, driven by a 240V AC input.
It watches the supply for Over/Undervoltage, measuring true RMS.
Its upper threshold adjusts across 180 to 300V AC, and its lower across 135 to 285V AC.
The drop-out point is fixed at 95% of the pick-up setting.
It trips after 0.5 s (fixed), picks up after 0.5 s and re-energises 1 s after the fault clears.
It has Socketable mounting and Plug In terminals.
