Lovato RM148 Earth Leakage Relay - Modular Residual Current Protection Relay 24-48VAC/DC
The Lovato RM148 is a modular earth leakage relay designed for residual current monitoring and electrical protection applications.
Featuring Type A residual current detection, a single fixed operating threshold, fixed tripping time, and compatibility with
24-48VAC/DC auxiliary supply, this relay provides reliable earth fault monitoring for industrial and commercial electrical installations.
The unit is designed for 35mm DIN rail mounting and requires an external toroidal current transformer.
Product Overview
The Lovato RM148 earth leakage relay is part of the Lovato RM series of modular residual current monitoring devices.
Designed for installation on standard 35mm DIN rails according to IEC/EN 60715, it operates with an external toroidal transformer
to detect earth leakage currents. The relay provides one fixed operating threshold, fixed trip delay, SPDT relay output,
front TEST button, and configurable automatic or manual reset functions.
