400+ Amp
100-800 Vdc Contactor
G V240
FEATURES
PCB mountable option allows lowest cost OEM solution by eliminating need for cables, wires and connector.
Hermetically Sealed – Designed to meet: UL1604 for Class I & II, Div 2 and Class III for use in hazardous
locations, IP67 for temporary water immersion for 30 min, SAE J1171 - external ignition protection, and
ISO8846 for protection against ignition around flammable gasses.
Meets CE Conformance standards.
High Efficiency Dual DC Coils – Very low 12, 24, or 48VDC continuous coil power with no EMI emissions or
cross-talk on your system control power. Ideal for battery powered systems or where low power is needed.
PWM coil options provide additional drive control flexibility.
Built-in coil suppression for all DC coils – Saves you engineering time and parts cost to add external coil suppression.
Not position sensitive – can be mounted in any position for ease of installation.

APPLICATION NOTES
• Contactors feature internal transorb for coil suppression. No external
diodes should be added across the coil.
• Power switching lifecycles are based on current flow from A1(+) to
A2(-). For best breaking performance, the contactor should be installed
so that current flows from A1(+) to A2(-). There are cases where the
contactor will interrupt power in the opposite direction but please contact
GIGAVAC to confirm suitability. Direction of current flow is not relevant
during make or when flowing on closed contacts. For bi-directional
contactors, please contact GIGAVAC.
• Applications with capacitors will require a pre-charge circuit.
• Electrical life rating is based on resistive load with 27µH maximum
inductance in circuit. Because your application may be different, we
suggest you test the contactor in your circuit to verify life is as required.
• End of life is defined as when the dielectric, insulation resistance or
contact resistance exceeds the specifications listed.
Notes & Definitions:
1/ Auxillary contact rating - 2A, 24Vdc Resistive load, 100,000
cycles. Minimum current is 1mA, 5V. The auxiliary contact is
mechanically linked to the main power contacts.
2/ 50 Mohms after life.
3/ Contactor can operate up to 125°C in special cases - contact
GIGAVAC for details.
4/ Customer must provide an external economizer that meets
the Pick-up Current, Coil Current, and Pick-up Current Time. For
detailed information click here Application Note AN-016 or visit
www.gigavac.com/application-notes.
5/ Because the contactor is operated by a coil that changes
resistance with temperature, the maximum coil voltage will be
lower than indicated at temperatures above 25C, and higher than
indicated at temperatures below 25C.
6/ Contactor has two coils. Both are used for pick-up, and then in
approximately 75 milliseconds, one coil is electronically removed
from the coil drive circuit. The remaining coil supplies low continu-
ous hold power sufficient for the contactor to meet all of its
specified performance specifications. This provides the lowest
coil power possible without the use of PWM electronics that have
been known to cause EMI emissions and/or cross-talk on your
system control power.
7/ Because the contactor is operated by a coil that changes
resistance with temperature, and because Nominal Coil Voltage
has been assumed for the Pick-up Current, Coil Current and
Coil Power specifications, Current/Wattage will be lower than
indicated at temperatures above 25C and higher than indicated at
temperatures below 25C.
8/ For Pick-up testing of contactors with dual coils, the voltage
can not be ramped up slowly, but must be applied instantly to
at least the maximum Pick-up Voltage or Current. Otherwise, the
contactor will not pick-up.
9/ Because the contactor is operated by a coil that changes
resistance with temperature, Pick-up Voltage and Drop Out
Voltage will be lower than indicated at temperatures below 25C
and higher than indicated at temperatures above 25C.
10/ These DC coils have built-in coil suppression. The use of
additional external coil suppression can slow the release time and
invalidate the life cycle ratings, or can cause the contactor not to
be able to interrupt the maximum current specified. If lower coil
back EMF is required, please contact GIGAVAC for assistance.
11/ All contact ratings and coil versions may not be UL
recognized. Contact GIGAVAC for a copy of the applicable
sections of the test report.
12/ Rated voltage refers to max voltage for which make/break
load cycles are provided. Contactor can be used in higher voltage
systems. Contact GIGAVAC for more info.
