Description

Monitoring voltage relay HRN-55Relay monitors phase sequence and failure ( e.g monitoring of correct motor winding etc.)in 3 phaze mainDESCRIPTION Monitoring of correct motor winding etc.. fixed delay T1 (500ms) and adjustable delay T2 (0.5-10s). Monitoring voltage relay in two variants:HRN-55: supply from all phases, which means that function of relay is applicable also if one phase fails.HRN-55N: supply L1-N, it means that relay also monitors break of neutral point. Faulty state is indicated by LED and output contact of relay is OFF.TECHNICAL PARAMETERS Monitored power voltage: HRN-55: 3 x 400 V HRN-55N: 3 x 400 V/ 230 V Umax: 125% of monitored voltage. Umin: 75% of monitored voltage. Output contact: 1x changeover 8 A/250 V AC1 (AgNi, 2500 VA). 1-MODULE, DIN rail mounting.
