Ground fault indication

relay - H550

Code requirements

Features

NFPA 70, the U.S. National Electrical Code (NEC) requires

that services of 1000 amps and larger in capacity which

Suitable for indicating a ground fault condition on a

generator set which is either locally or remotely

operate at more than 150 volts from line-to-neutral must be grounded.

provided with ground fault equipment. Generator sets rated

Power - Operates on 24 VDC (nominal) control power -

fully functional at voltages from 18-30 VDC.

at 100 amps and larger which serve as emergency power

must be provided with ground fault indication equipment.

Health care facilities that utilize ground fault protection

equipment must be provided with a coordinated multi-level

ground fault system.

Direct connection - Suitable for direct connection to

generator sets operating at voltages up to 600 VAC (line

to line).

Ground fault current settings - 100-1200 A, in 10

discrete settings: 100, 150, 200, 250, 300, 450, 600,

750, 800, 1200 A.

Cummins Power Generation ground fault indication

equipment is designed for use in emergency/standby power

systems, for indication of ground fault conditions during

generator set operation.

Monitoring - Provides continuous monitoring of

neutral-to-ground with LED indication for open

connection.

Factory mounted controls - Available factory-

mounted and interconnected to Cummins Power

Generation Detector™ series PowerCommand^®controls.

Link reconnection - For use with either 3-pole (solid

neutral or 4-pole (switched neutral) transfer switches.

Indicating lamps - For Relay on (green), ground fault

current over setting (red), loss of ground connection

(red).

Time delay settings - 0-1.0 seconds.

Circuit board - One-piece molded case fully potted.

Contacts - One set of form C output, rated 1100 VA,

250 VAC, 5 A continuous, 3 A breaking @ 240 VAC.

“Test” - Push-button.

“Reset” - Push-button.

Percent full scale metering output - 0-1 mA full

scale.

Bonding jumper - Sized per NEC requirements.
