Minimum current is 0.1mA, 5V. The auxiliary contact is mechanically linked to the main power contacts. 2 Contact resisitance measured at currents higher than 100A. 3 Operation time is measured at 25°C and includes maximum 7ms bounce. F = 48 Vdc, Internal Coil Suppression Coil Termination Notes & Definitions: 4 Insulation resistance is 50 Mohms after life. D = Coil Screw, M4 Blank = None B = SPST, Normally Open C = SPST, Normally Closed APPLICATION NOTES • Contactors feature internal transorb for coil suppression. No external diodes should be added across the coil. 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. • Power switching lifecycles are based on current flow from A2(+) to A1(-). For best breaking performance, the contactor should be installed so that current flows from A2(+) to A1(-). 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. 5 Contactor can operate up to 125°C in special cases - contact GIGAVAC for details. 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 continuous hold power sufficient for the contactor to meet all of its specified performance specifications. This provides low coil power without PWM electronics that can cause EMI emissions and/or cross-talk on control power. 7 Contactor is operated by a coil that changes resistance with temperature. Since pick-up current, coil current and coil power are specified at nominal voltage, they will be lower than indicated at temperatures above 25°C and higher than indicated at temperatures below 25°C. Similarly, pick-up and drop-out voltages will be higher than indicated at temperatures above 25°C and lower than indicated at temperatures below 25°C. 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. Otherwise, the contactor will not pick-up. 9 For AC power switching cycles, contact factory. Limit make current to 1000A to avoid contact welding. • 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 fails the specifications listed.
