© PHOENIX CONTACT 2009-11-17100464_en_05 CLIPLINE ECP… Data sheet 1D e s c r i p t i o n The ECP… electronic circuit breaker, which has a design width of just 12.5 mm, selectively protects all 24 V DC load circuits. This is achieved using a combination of active electronic current limitation and proven circuit breaker technology including electrical isolation. The ECP… can be plugged onto the proven TMCP SOCKET M base, which ensures quick and easy mounting. The ECP… can be used in a pplications that cover all aspects of the switched-mode power supply unit. In the event of an overload, switched-mode power supply units reduce the output voltage, which means that all the connected loads are no longer sufficiently supplied. This means that if an error occurs in one load of a system, the voltage will be affected in all load circuits. The ECP… solves this problem by always limiting the maximum possible current to 1.8 times (or 1.5 times) the value of the set nominal current. Capacitive loads can thus be switched on and loads are only switched off in the event of an overload or short circuit. An LED and integrated signal contacts indicate the operating and error states.

1.1 Properties

– Selective load protection with electrical isolation in the event of an error – All load types can be connect ed (small DC motors, etc. on request) – Active current limitation is typically 1.8 x I N (or typically 1.5 x IN at IN = 8 A or 10 A) when capacitive loads up to 20,000 µF are switched on and in the event of overload/ short circuit – Electronic shutdown characteristic curve – Safe overload shutdown from 1.1 x I N, even for long load cables or low cable cross-sections – Nominal current can be selected in fixed current strengths from 1 A ... 10 A or set to two levels (1 A/2 A or 3 A/6 A) using switches on the device – Manual on/off switch (push/push actuation) – Clear indication – 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… used. Make sure you always use the latest documentation.

3.3 Time-current characteristic (T A = 25°C)

Figure 3 Time-current characteristic time is 5 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 (short circuit (I K) to 5 s (in the event of overload with high cable attenuation)). – Without the current limitation typically activated at 1.8 x IN*, a significantly higher overcurrent would flow in the event of an overload or short circuit. – If the ECP... has detected an overload or short-circuit condition, the LED changes from green to orange. When the circuit breaker trips, the LED goes out. – The circuit breaker cannot be reset until the integrated bimetal has cooled down (approximately 10 s).

4 Mounting on a modular base

The TMCP SOCKET M base is snapped onto a DIN rail and can accommodate two ECP… 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... (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… 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.
