Chapter 1

TeSys GV5PB / GV6PB devices are equipped with toggle switch handles as standard.

The device operating controls, operation indicators, settings, and locking mechanisms are located on the front of the device.

Optional rotary handles are available in black or yellow. See Devices with Rotary Handle.

For devices with a rotary handle:

• The device operating controls are located on the front enclosure cover.

• The operation indicators and settings are accessible when the door is open.

• The locking mechanisms are located on the front enclosure cover (door closed).

Optional rotary handles are available in two colors:

• Black

• Yellow

NOTE: See instruction sheet GHD16292AA for information on mounting the extended rotary handle.

The rating plate on the front of the device identifies the device and its characteristics. The rating plate depends on the breaking performances.

Use sealing accessories to prevent device operations.

• GV5PB and GV6PB Motor Protection Circuit Beakers may be used between –13 to +158°F (–2 to +7°C). For temperatures higher than 104°F (40°C) inside the enclosure, devices must be derated. See Temperature Derating below.

• Circuit breakers should be put into service under normal ambient, operating-temperature conditions.

• The permissible storage temperature range for GV5PB and GV6PB Motor Protection Circuit Breakers

  in the original packing is –58 to +185°F (–0 to +85°C).

GV5PB and GV6PB Motor Protection Circuit Breakers are equipped with electronic trip units.

Electronic trip units are not affected by variations in temperature. If the trip units are used in high temperature environments, the Micrologic™ trip unit setting must take into account the temperature limits of the circuit breaker.

Changes in temperature do not affect measurements by electronic trip units.

• The built-in CT sensors with Rogowski coils measure the current.

• The control electronics compare the value of the current to the settings defined for 104°F (40°C).

Because temperature has no effect on the CT measurements, the tripping thresholds do not need to be modified.

However, the temperature rise caused by the flow of current combined with the ambient temperature increases the temperature of the device. To avoid reaching the thermal withstand value, it is necessary to limit the current flowing through the device, that is the maximum Ir setting as a function of the temperature.

See following indicates the maximum long-time (LT) protection setting Ir (A) depending on the ambient temperature.

TeSys GV5PB / GV6PB devices are designed to operate in industrial atmospheres as defined in IEC/EN 60947-2 standard for the highest level of pollution (level 3).

They are tested for extreme storage conditions according to the following standards:

It is recommended to install the device in a properly ventilated switchboard without excessive dust.

TeSys GV5PB / GV6PB devices are tested against vibration.

Conformity tests are carried out in accordance with IEC/EN 60068-2-6 standard at the levels required by merchant marine inspection organizations such as Bureau Veritas and Lloyd’s Register:

• 2 Hz to 25.0 Hz with an amplitude of +/- 0.063 in (+/- 1.6 mm)

• 25.0 Hz to 100 Hz at an acceleration of +/- 4.0 g

Excessive vibration may cause tripping, breaks in connection, or damage to mechanical parts.

TeSys GV5PB / GV6PB devices are immune to electromagnetic disturbance.

Overcurrent protection tests are carried out in accordance with the electromagnetic compatibility (EMC) standard (IEC/EN 60947-2 standard appendixes F and J).

Check for compliance with EMC standard by testing for immunity to:

• Overvoltages produced by the operation of electromagnetic switchgear.

• Overvoltages produced by atmospheric disturbance that pass through the electrical network (for example, lightning).

• The use of apparatus emitting radio waves (such as radio transmitters, walkie-talkies, or radar).

• Electrostatic discharges produced by the operators themselves.

Conformity with EMC standard as described above helps to ensure that:

• The device operates correctly in a disturbed environment:

  • Without nuisance tripping.

  • In accordance with the trip time.

• There is no disturbance to any type of industrial or commercial environment.

TeSys GV5PB / GV6PB devices are designed to operate within specification at altitudes of up to 6,600 ft (2,000 m).

Above 6,600 ft (2,000 m), modifying the characteristics of the surrounding air (dielectric strength, cooling capacity) causes derating as follows:
