Ramp characteristic curve

(“L” or “R” characteristic)

Over-current Releases (OCRs)

The AGR series of over-current releases (OCRs) featuring high reliability and multiple protection capabilities is available for

TemPower2

. Controlled by an internal 16-bit microprocessor, the OCR provides reliable protection against overcurrent.

The OCR range is divided into three groups: L-characteristic, R-characteristic (both for general feeder) and S-characteristic (for

generator protection).

Each group consists of:

Type AGR-11B: Standard OCR with adjustment dial

Type AGR-21B,22B: Standard OCR with L.C.D.

Type AGR-31B: Enhanced OCR with backlit L.C.D.

Optional protection functions of the OCR include those against ground fault, earth leakage, undervoltage and reverse power.

Pre-trip alarm function can also be installed.

Protective functions

Adjustable long time-delay trip function LT

RMS sensing is used to accurately read through distorted wave-

forms.

In addition to the standard L and S-characteristics, the R-char-

acteristic is available in five types for long time-delay trip.

The R-characteristic can be used to give selectivity with e.g.

fuses. (See P. 8).

HOT start mode (applicable to L-characteristic of AGR-

21B,31B)

HOT or COLD start mode is user-selectable.

In HOT start mode, the OCR operates faster than in COLD

start mode in response to an overload. The HOT start mode

gives protection, taking account of the behavior of loads under

heat stress.

Adjustable short time-delay trip function ST

The ST delay trip function has a “definite time delay character-

istic” and a “ramp characteristic”. These characteristics are

switch-selectable.

The ramp characteristic provides close selectivity with down-

stream circuit breakers or fuses.

The group AGR-L and AGR-R OCRs come in operation with

the definite time characteristic when the load current reaches

1000% or more of the rated current [

] (500% or more of the

rated current [

] for AGR-S).

The ST trip function is factory set to the definite time charac-

teristic.

Adjustable instantaneous trip function INST/MCR

The INST trip function trips the ACB when the short circuit cur-

rent exceeds the pickup current setting, irrespective of the state

of the ACB.

The making current release (MCR) trips the ACB when the

short circuit current exceeds the pickup current setting during

closing operation. After the ACB is closed, the MCR is locked

and kept inoperative.

The INST and MCR are switch-selectable for AGR-21B, 22B

and 31B. (AGR-11B is INST only , MCR is not selectable)

Note) The MCR needs the control power. If the control power

is lost, the MCR provides the INST trip function only.

Specifications

Undervoltage trip device (UVT)

The undervoltage trip device (UVT) trips the ACB when the

control voltage drops below the opening voltage. When the

control voltage is restored to the pick-up voltage, the ACB can

be closed. The pick-up voltage is fixed to 85% of the rated

voltage.

The UVT consists of a tripping mechanism and an undervoltage

trip control device. The trip control device is available in two

types: AUR-ICS and AUR-ICD.

Type AUR-ICS provides an instantaneous trip to the ACB when

the control voltage drops below the opening voltage. Type AUR-

ICD provides a delayed trip to the ACB when the control volt-

age remains below the opening voltage for at least 500 ms.

Adding a pushbutton switch (with normally opened contacts)

between terminals 24 and 30 allows the ACB to be tripped

remotely.

Undervoltage trip control circuit (for AC)

1 Tripping signal is 48 VDC/5 mA.

Apply tripping signal for at least 80 ms. If a constant
tripping signal is applied a n/o auxiliary switch must be
used in series with the PB.
