EC-E... Electronic miniature circuit-breaker CLIPLINE Data sheet 103906_en_01 1 (c) PHOENIX CONTACT - 09/2009 Description The EC-E... electronic miniature circuit-breaker selectively protects all 24 V DC load circuits on power supply units. A combination of active electronic current limitation for short circuits and an overload shutdown function from 1.1 x IN upwards ensures that the miniature circuit-breaker can react to overloads faster than the power supply unit. In this case, the residual current is constantly restricted to 1.3 1.8 times the nominal current. This enables capacitive loads of up to 20, 000 F to be switched on; loads are shut down only in the event of an overload or short circuit. Once an overload or short circuit has been detected in the load circuit, the load output of the EC-E... is blocked. The current flow in the faulty circuit is interrupted. The EC-E... and, therefore, the current circuit can be activated again using the electronic reset input or manually on the device using the slide switch. Wiring and signaling tasks can be implemented easily using power rails and plug-in bridges. A multi-color LED and the integrated status output display the operating and fault state. The miniature circuit-breaker has a design width of 12.5 mm and can be snapped onto NS 35 DIN rails using a modular approach. It is equipped with screw connections. 1.1 - - - - - - - - - Properties Selective load protection, electronic shutdown characteristic curve Active current limitation when switching on capacitive loads of up to 20, 000 F and in the event of an overload/short circuit Nominal current can be selected in fixed current strengths from 0.5 A ... 12 A Safe overload shutdown from 1.1 x IN upwards, even with long load lines or small cable cross-sections Manual on/off switch (S1) Clear signaling by means of LED, SF status output, or F alarm output (signal contact), (can be combined) RE electronic reset input (option) Integrated fail-safe element, adapted to nominal current Straightforward wiring using LINE+ power rail and 0 V, as well as signal rails and signal bridges NOTE: Make sure that you adapt the cable cross-section of the relevant load circuit to the nominal current of the EC-E... being used. Take special precautions in the system or machine to eliminate the possibility of system parts restarting (in accordance with the Machinery Directive 2006/42/EC and EN 60204-1). In the event of a fault (short circuit/ overload), the EC-E... shuts down the load circuit electronically. Make sure you always use the latest documentation.

The electronic current limitation function is typically used from 1.8 x IN* upwards. This means that, typically, 1.8 times the nominal current* is flowing in the case of all overload conditions that lead to a shutdown (regardless of the power supply and load circuit resistance). The shutdown time ranges from 100 ms to 3 s depending on the multiple of the nominal current, or in the event of a short circuit (IK). Without the current limitation function used at, typically, 1.8 x IN*, a considerably higher overcurrent would flow in the event of an overload or a short circuit. Current limitation typically 1.8 x IN where IN = 0.5 A ... 6 A Current limitation typically 1.5 x IN where IN = 8 A or 10 A Current limitation typically 1.3 x IN where IN = 12 A 103906_en_01 PHOENIX CONTACT 8 EC-E... 3.7 Safe shutdown Safe shutdown of the EC-E... with different supply line lengths and cable cross-sections Specific electrical resistance for electrolytic copper: 0 = 0.0178 ( x mm)/m UB = 19.2 V DC (80% of 24 V DC) The voltage drop on the EC-E... and the tolerance of the shutdown point (typically 1.1 x IN = 1.05 ... 1.35 x IN) have already been taken into account.
