Altitude
Refers to the height of the site where the equipment is located, expressed in
meters above the sea level.
Ambient temperature
Temperature of the air surrounding the unit.
Circuits
• Auxiliary circuit
All the conducting parts of a contactor, intended to be included in a circuit
different from the main circuit and the control circuit of the contactor e.g.
signalization, interlocking circuits etc …
• Control circuit
All the conducting parts of a contactor (other than the main circuit) included in
a circuit used for the closing operation, or opening operation, or both, of the
contactor.
• Main circuit
All the conducting parts of a contactor included in the circuit which it is designed
to close or open.
Coil operating range
Expressed as a multiple of the rated control circuit voltage Uc for the lower and
upper limits.
Cycle duration
Total time of the on-load + off-load period.
Endurance / durability
• Electrical endurance
Number of on-load operating cycles (i.e. with current on the main contacts) a
contactor can achieve, varies depending on the utilization category.
• Mechanical endurance
Number of off-load operating cycles (i.e. without current on the main contacts) a
contactor can achieve.
Inching
Energizing a motor once or repeatedly for short periods to obtain small
movements of the driven mechanism.
Insulation class according to the VDE 0110 and NFC 20-040
Characterizes contactors suitability in accordance with environment and
utilization conditions. A contactor can be classifi ed depending on its own
clearance and creepage distances in the insulation classes A, B, C, D which
correspond to different insulation voltage values.
The insulation class C is applicable to most of the industrial applications.
Equipment described in this catalogue correspond to insulation class C.
Intermittent duty
Duty in which the main contacts of a contactor remain closed for periods of time
insuffi cient to allow the contactor to reach thermal equilibrium, the current-
carrying periods being separated by off-load periods of suffi cient duration to
restore equality of temperature with the cooling medium.
Mounting positions
Stated by the manufacturer. Please note restrictions when applicable.
On-load factor
Ratio of the current fl ow time to the total time of the cycle x 100.
Plugging
Stopping or reversing a motor quickly by interchanging two supply leads whilst
the motor is running.
Rated breaking capacity; Rated making capacity
Value of r.m.s current a contactor can break or make at a fi xed voltage value,
within the conditions specifi ed by the standards, depending on the utilization
category.

Technical data
Technical terms and defi nitions
Rated control circuit voltage Uc
Control voltage value for which the control circuit of the unit is sized.
Rated insulation voltage U
Voltage value which designates the unit and to which dielectric tests, clearance
and creepage distances are referred.
Rated impulse withstand voltage U
The highest peak value of an impulse voltage of prescribed form 1.2/50, which
does not cause breakdown under specifi ed conditions of test.
Rated operating current I
Current value stated by the manufacturer and taking into account the rated
operating voltage U
the electrical contact life and the type of the protective enclosure.
Rated operating voltage U
Voltage value to which utilization characteristics of the contactor are referred, i.e.
phase to phase voltage in 3 phase circuits.
Conventional thermal current I
Value of current the contactor can withstand with poles in closed position, in
free air for an eight hour duty, without the temperature rise of its various parts
exceeding the limits specifi ed by the standards.
Resistance to shocks
Requirements applicable for instance to vehicles, crane operation or switchgear
slide-in module systems.
At the quoted permissible «g» values, contactors must not undergo a change in
switching state and O/L relays must not trip.
Resistance to vibrations
Requirements applicable to all the vehicles, vessels and other similar transport
systems. At the quoted amplitude and vibration frequency values, the unit must
be capable to achieve the required duty.
Short-circuit protection co-ordination
Achieved by using back-up protection devices such as circuit-breakers, H.R.C.
fuses or standard fuses.
Co-ordination types a, b, c are defi ned in IEC 292-1 publication, VDE 0660, NFC
63-650 standards. Co-ordination types "1" and "2" are defi ned in IEC 947-4-1.
• Type 1 co-ordination
There has been no discharge of parts beyond the enclosure. Damage to the
contactor and the overload relay is acceptable.
• Type 2 co-ordination
No damage to the overload relay or other parts has occured, except that welding
of contactor or starter contacts is permitted, if they are easily separated.
Switching frequency
Number of operating cycles per hour.
Time
• Closing time
Time between energization of the coil until the moment the contacts of the fi rst
current path to be closed actually close.
• Opening time
Time from the beginning of state causing breaking until the moment when the
contacts of the last current path to be opened are open.
• Minimal operation time
Shortest control duration to ensure complete closing or opening of a contactor.
• Short time current permissible
Value of current which the contactor can withstand in closed position for a short
time period and within specifi ed conditions.
• Time constant
Ratio of inductance to the resistance : L/R = mH/Ohm = ms.
