Protection Relays & Controls

Wiring Diagram

FEATURES

BENEFITS

Arc-Flash trip time <1 ms

Limits arc-flash damage and risk of injury

Multiple sensors (up to 24)

Single module can monitor 6 sensors. Up to 4 PGR-8800 units can be linked into one system

Fail-safe system

Continuous monitoring of optical sensors and inputs ensures protection

Redundant trip circuit

Solid-state backup arc-detection circuit adds a second layer of safety

Adjustable light sensitivity

Allows for operation in bright environments and maximum sensitivity in dark environments

LED indication (on unit and each sensor)

18 LEDs provide at-a glance status for module and I/O state

Current detection

Phase-CT inputs provide overcurrent protection and prevent nuisance trips

Optical detection

Point and fiber-optic sensors provide wide detection area with sensor health trip indication

Digital inputs (6)

Two each: remote trip, inhibit, and reset inputs

Service mode

Allows for system test without tripping

Trip coil contact

Solid-state 24-300 Vdc/24-300 Vac IGBT

Indication contacts

Form C and status outputs

USB interface

Data logging and configuration software uses a USB interface with no drivers or software installation

Built-in sensor

Can be used in single-sensor systems, as a seventh sensor, and for calibration

Universal power supply/Battery backup

100-240 Vac, 14-48 Vdc, or 110-250 Vdc supply accepted. Ability to charge and run off an external, user-supplied

24 Vdc battery.

Data logging

On-board event recorder helps with system diagnostics

Modbus

Remotely view measured values, event records & reset trips

Upstream Tripping

Ability to trip upstream device if the local breaker fails to clear the fault

PGA-LS10 (A1000) Point Sensor

Line-of-sight light sensor detects an arc as small as 3 kA

within a 2-m half-sphere. Sensor health and trip indication.

Dimensions: See PGR-8800 Manual

PGA-LS20 (A2000)/PGA-LS25 (A2000.0020)/PGA-

LS30(A2000.0030) Fiber-Optic Sensor

360° light sensor for tricky installations with many shadows

or to run along bus bars. Sensor health and trip indication.

Dimensions: See PGR-8800 Manual

PGA-1100 (D1100) Diode Logic Unit

This module allows multiple PGR-8800 relays to trip the

same breaker, for example an upstream or a tie-breaker.

Dimensions: H 80mm (3.15”) W 20mm(.79”) D 70mm(2.76”)

Current Transformers

Eliminate nuisance arc-flash trips and use for

overcurrent protection.
