PMA30240 - CURR.REL.1OUT.24-240VAC/DC MIN-MAX CURR.

Why Choose the PMA30240?

The Lovato PMA30240 current monitoring relay delivers dependable AC/DC minimum or maximum current control across single- and three-phase systems. With a broad 24...240VAC/DC supply range and one relay output, SKU PMA30240 integrates easily into new builds and retrofits. Select 5 A or 16 A rated current and fine-tune thresholds using front potentiometers for precise, repeatable protection and signalling.

Built on the PMA30 platform, this compact unit withstands 4 kV impulse surges and operates from -20 to +60 °C for reliable performance in control panels. An Ith (IEC) of 8 A and mechanical life of 30,000,000 cycles support durability, while compliance with IEC/EN 60255-5, 61000-6-2/6-3, UL 508 and CSA C22.2 n° 14 aids specification and approval.
