2 - Operating features
Introduction
Ekip Dip has been developed and certified to function in specific environmental, electrical and mechanical
conditions; full details are available in the Technical catalog.
The following sections describe the electrical and power supply characteristics that enable Ekip Dip and the
relative electronic accessories to operate correctly.
Electrical characteristics
The Ekip Dip measurement and protection functions described in this document are guaranteed with current
values within the following nominal ranges:
Parameter Rated operating range
Primary current 0,004 ÷ 16 In
(1)
Rated frequency 45 ... 55 Hz (with fn= 50 Hz) / 54 ... 66 Hz (with fn= 60 Hz)
Peak factor Complying with standard IEC 60947-2
(1)
range with reference to each phase; In refers to the rated size defined by the Rating plug installed on the Trip
unit, available in models from 100 A to 6300 A
Self-supply
The internal current sensors are able to supply the Trip unit directly
Parameter Operating limits
Minimum three-phase turn-on
current
> 30 A (E2.2 with Rating Plug < 400 A)
> 80 A (E2.2 with Rating Plug ≥ 400 A and E4.2)
> 160 A (E6.2)
Auxiliary power supply
Ekip Dip can be connected to an external auxiliary supply source, which is useful when certain functions such
as communication via Local Bus, recording manual operations, certain measurements and the datalogger
must be activated.
The auxiliary supply can be provided by modules from the Ekip Supply range or via a direct connection
to the terminal box; the direct connection must be made when the following operating conditions can be
guaranteed:
Parameter Operating limits
Voltage 24 VDC galvanically isolated
Tolerance ± 10%
Maximum ripple ± 5%
Maximum inrush current @ 24 V 10 A per 5 ms
Maximum rated power @ 24 V 4 W
Connection cable
Insulated with grounding cable (same characteristics as Belden
3105A/B or higher)
IMPORTANT: if connection is direct, the power supply must be galvanically insulated
and provide the insulation characteristics established by standard IEC 60950 (UL
1950) or equivalent.
