Product Details

CM-SRS Current Monitoring, Single Phase AC/DC

Depending on the configuration, the current monitoring relays CM-SRS.1 and CM-SRS.2 can be used for over- or undercurrent monitoring in single-phase AC and/or DC systems. The current to be monitored (measured value) is applied to terminals B1/B2/B3-C. The devices work according the open-circuit principle.

If the measured value exceeds resp. drops below the adjusted threshold value, the output relay(s) energize(s): on the CM-SRS.1 immediately, on the CM-SRS.2 after the set tripping delay TV.

Monitoring of DC- and AC-currents: CM-SRS.x1: 3mA - 1A and CM-SRS.x2: 0.3-15A
RMS measuring principle
One device includes 3 measuring ranges
Over- or undercurrent monitoring configurable
Hysteresis adjustable from 3-30%
Tripping delay TV adjustable 0.1-30s
CM-SRS.1: 1 c/o contact
CM-SRS.2: 2 c/o contacts
22.5mm width
3 LED's for status indication
