CI-tronic™ Electronic contactors Type ECI

ECI electronic contactors are designed for fast and demanding switching of loads such as heaters, solenoids, transformers and motors. ECI Electronic contactors utilize power chip with LTE (Low Thermal Expansion) technology. This unique power chip design ensures high switching capacity and long life.

The contactors are burst ﬁred for reduced EMC emission, have LED status indicators and accept universal control voltage ranges.

The units are DIN rail mountable, complete with heatsink and require no additional components.

Overheat protection If required the controller can be protected

against overheating by inserting a thermostat in the slot on the right-hand side of the controller.

Order: UP 62 thermostat 037N0050

The thermostat is connected in series with the control circuit of the main contactor. When the temperature of the heat sink exceeds 100 °C the main contactor will be switched OFF. A manual reset is necessary to restart this circuit.

IC.PD.C50.G4.02 | 5

Mounting instruction The controller is designed for vertical mounting.

If the controller is mounted horizontally the load current must be reduced by 50%. The controller needs no side clearance. Clearance between two vertical mounted controller must be minimum 80 mm / 3.15”. Clearance between controller and top and bottom walls must be minimum 30 mm / 1.2”.
