DEFINITE TIME OVER CURRENT RELAY Description and Specifications for Lab Tenders
DEFINITE TIME OVER CURRENT RELAY
module with insulated panel, definite time over-current relay, relay for
monitoring the current of a three-phase load (typically a motor) and performing
a protection with alarm. Max. adjustable set point, divided in 10 parts.
Adjustable timer (0.1 ... 30 s).
The delay time must start
as soon as the current exceeds the max set point. Adjustable initial timer (0.1
... 30 s).
The timer must activate
when the current exceeds 5% of the max range. Current range: 0.25 ... 5 A with
(galvanic isolation). For currents higher than 5 A an external CT.../5 A must
be used). One changeover contact: 5 A /
230 Vac with resistive load. NC contacts: device not supplied or in alarm.
Supply voltage: single-phase from main. 4 mm. safety terminals and 2 mm.
terminals included on the front panel for the electrical connection..
