  • Page 3: General Description

    DC current sent through the secondary windings of a CT can bias its core enough to shift the trip point outside specification on sensitive settings. For the CT supervision to work, either the special Eaton’s Cutler- Hammer C311CT zero sequence current transformer with a turns ratio of 10000:1, or the standard family of Series A2 C311CT zero sequence current transformers with a turns ratio of 500:1 must be installed, as specified in section 3.2.
  • Page 4: Operation

    PUB 50413 D64RPBH13 SERIES B1 GROUND FAULT RELAY Pull-apart terminal blocks simplify connection of field wiring. They have two 12 AWG screw clamps per pole with 90° and 180° orientation. Captive screws secure the blocks to the relay, safe from the effects of shock and vibration.

    200 Amps to 2000 amps when using the special Eaton’s Cutler-Hammer C311CT zero sequence current transformer with a turns ratio of 10000:1. With Inhibit Enabled, if the ground fault current exceeds the inhibit level the output circuit breaker will be inhibited until the ground fault current drops below the inhibit level.
  • Page 6: Ground Fault Trip Delay

    2.2.2 GROUND FAULT TRIP LEVEL The ground fault TRIP LEVEL range is either 50 - 1200 Amps when using the special Eaton’s Cutler- Hammer C311CT zero sequence current transformer with a turns ratio of 10000:1 or 2.5 – 60 Amps when using the standard family of C311CT zero sequence current transformers with a turns ratio of 500:1.

    PUB 50413 D64RPBH13 SERIES B1 GROUND FAULT RELAY 2.2.4 OUTPUT CIRCUIT BREAKER OPERATING MODE –CONTACT STATE The two different OPERATING MODES are described under the glossary of terms. The setting of DIPswitch 12 determines the operating mode of the D64RPBH13 output circuit breaker. This is shown in Table 4.
  • Page 9: G/F Test - Reset

    PUB 50413 D64RPBH13 SERIES B1 GROUND FAULT RELAY Two .25 s flashes every few seconds means that the ground fault current exceeded the Trip Inhibit Level but the upstream device failed to trip during 1.2 s. The D64RPBH13 then tripped as a last resort. The contactor should be replaced since its contacts may well be damaged.
  • Page 10: Memory After Loss Of Control Voltage

    PUB 50413 D64RPBH13 SERIES B1 GROUND FAULT RELAY MEMORY AFTER LOSS OF CONTROL VOLTAGE When control voltage is removed from the D64RPBH13, the LAST TRIP registration will be memorized (for at least one week). Pressing the Reset pushbutton before restoring control voltage will light either the green LED or the red LED, green indicating no trip was registered and red indicating the opposite.
  • Page 11: External C311Ct Current Transformer

    D64RPBH13 SERIES B1 GROUND FAULT RELAY EXTERNAL C311CT CURRENT TRANSFORMER The D64RPBH13 is designed to operate with either, a special Eaton’s Cutler-Hammer C311CT zero sequence current transformer with a turns ratio of 10000:1 or, the standard family of C311CT zero sequence current transformers with a turns ratio of 500:1.
  • Page 12: Catalog Numbers

    For mounting dimensions and additional information on C311CT current transformers refer to the current Eaton’s Cutler-Hammer catalog. The D64RPBH13 is designed to operate with special Eaton’s Cutler-Hammer C311CT current transformers having a turns ratio of 10,000:1. Each C311CT is epoxy molded for exceptional mechanical properties and has a high-grade silicon iron core for excellent coupling characteristics.
