Monitoring current relay
MCR 515
! To monitor heating rods in shunts, heating cables, consumption of
one-phase motors, indicates current flow
! Flexible adjustment by potentiometer, choise of 6 ranges:
0.05 - 0.5 A; 0.1 - 1 A; 0.2 - 2 A; 0.5 - 5 A; 0.8 - 8 A; 1.6 - 16 A
.
! Adjustable delay 0.5 - 10 s to eliminate short current peaks
.
! Possible to use current scanning from current transformer - up to 600 A
.
! Universal supply AC 24 - 240 V and DC 24 V
.
! Supply is not galvanically separated from measured current, it must
be in the same phase
.
! Output contact: 1 x changeover 8 A
.
! 1-phase, 1-MODULE, DIN rail mounting

Description
Function description
Monitoring relay MCR 515 serves to monitor current level
in one-phase AC circuits. Gradual setting of actuating
current of monitoring relay enables many different
applications. Output relay is in normal state open. After the
set current level is reached, relay closes after the set delay
(0.5-10 s). When returning from faulty to normal state there
is a hystersis (5 %). Multi-voltage of this relay is an advantage.
It is possible to monitor load which doesn´t have the same
supply as monitoring relay MCR 515. Range of MCR 515
can be increased by an external current transformer.
