Why Choose the PMA50A240?
The Lovato PMA50A240 pump protection relay safeguards single-phase and three-phase installations by supervising maximum AC current and minimum COSΦ, and by detecting phase loss or incorrect phase sequence. Operating from 220…240VAC with one relay output, it offers rated current Ie options of 5 A or 16 A. Simple configuration via potentiometers makes setup straightforward for panel builders and maintenance teams.
Designed to the PMA50 platform, this relay combines durability and electrical robustness, with 6 kV impulse withstand and a mechanical life of 30,000,000 cycles. It operates reliably from -20 to +60 °C and accepts secure terminations up to 0.8 Nm. Conformity includes IEC/EN 60255-5, 61000-6-2, 61000-6-3, UL 508 and CSA C22.2 n° 14, supporting wide-ranging control panel requirements.
