© PHOENIX CONTACT 2010-12-17102898_en_03 CLIPLINE ECP-E… Data sheet 1D e s c r i p t i o n The ECP-E… electronic circuit breaker can be used in applications that cover all aspects of the switched-mode power supply unit. In the event of an overload, switched-mode power supply units reduce their output voltage, which means that all the connected loads are no longer sufficiently supplied, e.g., in the event of a short circuit at the load. The solution here is the ECP-E… electronic circuit breaker, which selectively protects all 24 V DC load circuits. The ECP-E… constantly limits the re sidual current to 1.8 times (or 1.5/1.3 times) the protected nominal current. Capacitive loads can thus be switched on and loads are only switched off in the event of an overload or short circuit. After detecting an overload or short circuit in the load circuit, the load output of the ECP-E… is disabled. The current flow in the faulty circuit is interrupted. The ECP-E… and therefore the circuit can be activated again via the electronic reset input (13;14) or manually on the device via the slide switch. A multi-color LED and the integrated status output (12) indicate the operating or error state. The ECP-E… offers quick and space-saving assembly, as it can be plugged onto the TMCP SOCKET M and has a low design width of just 12.5 mm.
1.1 Properties
– Selective load protection, electronic shutdown characteristic curve – Active current limitation when switching on capacitive loads up to 20,000 µF and in the event of overload/short circuit – Nominal current can be selected in fixed current strengths from 1 A ... 12 A – Safe overload shutdown from 1.1 x I N, even for long load cables or low cable cross-sections – Manual on/off switch (S1) –I n d i c a t i o n b y m e a n s o f LED, status output SF – Electronic reset input RE – Integrated failsafe element – Design width of just 12.5 mm per channel – Can be plugged into a modular base NOTE: Make sure that the cable cross-section of the relevant load circuit is adapted to the nominal current of the ECP-E… used. In the system or machine, take special precautionary measures to prevent system parts from restarting (according to Machinery Directive 2006/42/EC and EN 60204-1). In the event of an error (short circuit/overload), the load circuit is electronically shut down by the ECP-E…. NOTE: Make sure that the cable cross-section of the relevant load circuit is adapted to the nominal current of the ECP-E… used. Make sure you always use the latest documentation.

3.4 Time-current characteristic (T A = 25°C)
Figure 3 Time-current characteristic is 3 s. – The electronic current limit ation is typically activated from 1.8 x IN*. This means that under all overload conditions (regardless of the current supply and load circuit resistance), 1.8 times the nominal current* typically flows until shutdown. The shutdown time ranges from 100 ms to 3 s depending on the multiple of the nominal current or in the event of short circuit (IK). – Without the current limitat ion typically activated at 1.8 x IN*, a significantly higher overcurrent would flow in the event of an overload or short circuit. * Typical current limitation 1.8 x I N at IN = 1 A ... 6 A Typical current limitation 1.5 x IN at IN = 8 A or 10 A Typical current limitation 1.3 x IN at IN = 12 A Stop point typ. 1,1 x l 1 , 8xl Switching tim e [s] Multiples of IN N N 0,01 0,1 102 3 IK

4 Mounting on a modular base
The TMCP SOCKET M base is snapped onto a DIN rail and can accommodate two ECP-E… devices. The two-channel bases are modular, which means that larger distribution systems can be created. A connection element is inserted at both the start and end of the system. Current distribution on the individual channels with a common supply (positive pole) is achieved by inserting a power rail in the slot provided on the connection side of the modules. All electrical connections are established using spring-cage terminal blocks. The reference potential for the ECP-E… (GND pin 11) is also looped through and led to the side connection elements. By connecting together the individual bases, all the internal wiring is established for the ground potential and group error message. The ECP-E… has an integrated signal contact (PDT). The SC-S0 contact is used for the group error message. The contacts for this indication are already connected in series in the bases and are connected to the side connection elements via two connections (13, 14). In each base, the series circuit can be contacted using a test socket and any interruptions can thus be determined.
