| Datasheet | Download Datasheet |
The Schneider Electric 841CS5-UNI is a 17.5 mm current monitor relay with SPDT output and rated 15 A at 240 V AC (50/60 Hz), 15 A at 24 V DC, driven by a 24-240V AC input.
It watches the monitored current for AC overcurrent.
The current is sensed by a inner shunt (terminals A1-B1); direct sensing or through an external current transformer.
Its trip point adjusts anywhere across 0.5-5 A AC.
It trips after 0 to 10 s (adjustable).
It has DIN Rail mounting and screw terminals.
