Schneider Electric Vigirex 56274 Residual Current Protection Relay - RH99P - Front Panel Mounting - 30mA To 30A - 380/415V AC - 50/60Hz

Features

Protection: when detecting significant leakage current in the line it monitors, the relay trips the breaker at the top end of it, through its shunt trip auxiliary

Monitoring: signalling leakage current by LED, bargraph or digital display on front, and by an output dry contact. Available in single-line and multi-line variants monitoring up to 12 different distribution lines.

Residual current sensitivity ranging from 30 mA to 30 A, fixed or adjustable, for A type relays,
and 30 mA to 3 A for B type relays

Trip time delay ranging from 0 to 4.5 seconds, fixed or adjustable
o Networks with operating voltage up to 1000 V, and frequency up to 400 Hz
o lines with current carrying capacity up to 3200 A
o main switchboards (at the foot of the transformer) in most demanding industrial environments (overvoltage withstand category IV)

Type A or type B as per IEC 60 755

Compliant with standards:
o IEC 60 755 and IEC 60947-2 appendix M (certificates by Kema laboratories available)
o UL 1053 listed, CSA C22.2 N° 144 for North-America
o EAC for Russia, CCC for China

DIN profile, to clip on rail or secure on backplate

72x72mm, for switchboard front plate or door mounting, using clips
o Closed toroids; for new installations (new switchboards or extensions), with cable capacity up to 630 A for A type relays, 250 A for B type relays
o Rectangular sensors; for lines with capacity up to 3200 A (busbars, or cables above 630 A)
o Split toroids; to equip distribution lines already in operation, with cable capacity up to 250 A

Applications

Electrical networks operating with voltage above 500 V (up to 1000) or frequency higher than 60 Hz (up to 400)

Distribution lines with capacity 630 A and above (up to 3200)

Upgrade of switchboards already in operation
