Overview
The REL52015 is a Schneider PowerLogic universal protection relay rated at 48.0 W on a 230 V supply, housed in a 20TE package with IP54 front protection. It carries 1 watchdog and 5 outputs, plus 1/5 A CT inputs for phase and residual current and a 100 V/110 V VT voltage input. The relay includes an LCD 128 x 64 pixel display with single-line diagram, embedded HTTP server, and conformal coating for harsh environments. It is certified to IEC standards.
Comparison with REL52011
Compared to the REL52011, the REL52015 draws double the power (48.0 W vs 24.0 W) and operates at a fixed 230 V supply versus the REL52011's 48 V. The REL52015 uses ring-lug CT terminals, while the REL52011 uses pin terminals for CT connections. The operating threshold is 110...230 V AC/DC on the REL52015 versus 24...230 V AC/DC on the REL52011.
