Phase Monitor Relay 460-600V AC
The Macromatic PMP575 is a plug-in phase monitor relay designed for industrial electrical control panels. It protects three-phase equipment by monitoring voltage conditions across a 460 to 600V AC input range. The unit features an octal base with eight pins for secure socket mounting. It suits maintenance engineers and panel builders responsible for motor protection.
Monitors Overvoltage Undervoltage Phase Loss
This relay continuously checks for overvoltage, undervoltage, phase loss, phase reversal and phase unbalance. Contacts are rated at 10 A at 277V AC and 7 A at 30V DC with an SPDT form. The auto and manual restart modes include a configurable delay from 1 to 300 seconds. Electrical operating durability is rated for 100, 000 cycles.
Replaces Fixed-Timer Or Non-Monitoring Relays
The PMP575 upgrades basic control circuits that lack comprehensive phase monitoring or adjustable restart logic. It adds automatic fault detection and flexible recovery timing in a compact 2.9 in deep body. The jump is worth it when equipment downtime from phase faults must be minimised without external timing modules. Not for single-phase systems or voltages outside the 460-600V AC range.

Questions about this item
How do I choose between the auto and manual restart modes on this relay?
The relay supports both auto and manual restart; select auto for automatic recovery after a fault clears, or manual when you want an operator to confirm before restart.
What does the 10 A contact rating at 277 V AC mean for my control circuit?
It means the SPDT contacts can switch up to 10 amps at 277 volts AC, so size your control wiring and protective devices for that maximum load.
How does the 8-pin octal base affect installation in my panel?
The octal 8-pin plug-in base fits standard octal sockets, allowing quick mounting and removal without hard-wiring each terminal.
