DEFINITE TIME OVER CURRENT RELAY

Model HV-EXP5215
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 direct insertion (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..
