4 - Operating features

Introduction Ekip Touch 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 Trip unit and
the relative electronic accessories to operate correctly.

Electrical characteristics The Ekip Touch measurement and protection functions described in this document are provided with
primary voltage and current values within the following nominal ranges:
Parameter Rated operating range
Primary current 0,004 ÷ 16 In (1)
Primary voltage 5 ÷ 690 V AC (2)
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, depending on the circuit-breaker model
used
(2) for Ekip Touch rated highest line-to-line voltage connected directly to Trip unit, also to sockets
inside the CB; external transformers must be used for higher voltage values, consult the chapter
dedicated to the Measurement modules

Self-supply The internal current sensors are able to supply the Trip unit directly; Ekip Touch versions Hi-, G, G Hi- are
also fitted with the Measurement enabler with voltage sockets module, which allows the Trip unit to be
supplied by the installation voltages as well:

Parameter Operating limits
> 30 A (E1.2-E2-2-E4.2 with Rating Plug < 400 A)
Minimum three-phase turn-on current > 80 A (E1.2-E2-2-E4.2 with Rating Plug ≥ 400 A)
> 160 A (E6.2)
Minimum three-phase turn-on voltage > 80 V

Auxiliary power supply Ekip Touch 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 if available.
The auxiliary supply can be provided by modules from the Ekip Supply range or by direct connection to
the terminal box.
Direct connection must guarantee the following operating conditions:
Parameter Operating limits
Voltage 24 V DC galvanically isolated
Tolerance ±10%
Maximum ripple ±5%
Maximum inrush current @ 24 V 10 A per 5 ms
Maximum rated power @ 24 V 4 W
Insulated with grounding cable (same characteristics as
Connection cable
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.
