Module 17plus Description Module 17plus is a mounting and power distribution system for use with the following plug-in type devices: ● ● ● Circuit breakers type 2210-S, 3600, 3900 Electronic circuit breakers and protectors type ESS20, ESX10 Solid state remote power controller E-1048-7.. Each module accommodates two breakers with an individual housing width of 12.5 mm and fits onto all industry standard mounting rails. The two-way modules are mounted side-by-side to provide as many ways as required with a terminal block fitted at each end for connection of signalling circuits. Electrical connections are by means of screwless spring-loaded terminals. Fitting a busbar on the terminal side of the modules provides power distribution onto the individual ways with a common line entry. When plugging in multipole circuit breakers, the busbar cannot be used. In this case each pole has to be individually connected. All internal wirings for the ground potential and the group signal are established by the side-by-side mounting of the individual modules (centre pieces, terminal blocks). The suitable circuit breakers or SSRPCs have integral signal contacts (break and make contacts). Depending on the application they can be used for single or group signalling. When using multipole breakers, auxiliary contacts are required in each pole so as not to interrupt the current loop of the group signalling by missing auxiliary contacts. Fitted with 2210-S: The integral auxiliary contacts of thermal–magnetic circuit breaker type 2210-S (make and break) can be used for single or group signalling, depending on the application. For group fault signalling all required terminals (make contacts, they open in the event of a failure) within the Module 17plus are connected in series. Group signalling is realised via the terminals on the side (13, 14). Single signalling requires connection of the break contacts (they close in the event of a failure). In this case one side of the contacts in the modules is connected in parallel (pin 11). The second contact side is accessible per module way and can be connected via terminal (pin 12). Both types of signalling are available at the same time, if the circuit breaker type used has auxiliary contacts (please note when ordering). Fitted with 3600/3900: The integral auxiliary contacts of thermal–magnetic circuit breaker types 3600/3900 (make and break) can be used for single or group signalling, depending on the application. For group fault signalling all required terminals (make contacts, they open in the event of a failure) within the Module 17plus are connected in series. Group signalling is realised via the terminals on the side (13, 14). Single signalling requires connection of the break contacts (they close in the event of a failure). In this case one side of the contacts in the modules is connected in parallel (pin 11). The second contact side is accessible per module way and can be connected via terminal (pin 12). Both types of signalling are available at the same time. 1 17plus Fitted with ESS20-1: The reference potential for the ESS20-1.. (Gnd pin 11) is also looped through and connected to the terminal elements at the sides. The integral signal output SF of the ESS20-124 can be tapped at terminal 12 of the relevant channel (single signalling). The reset input RE can be connected via terminal 13 or 14. Fitted with ESX10: The reference potential for the ESX10 (Gnd pin 11) is also looped through and connected to the terminal elements at the sides. The integral signal output SF of the ESX10-104/-124 can be tapped at terminal 12 of the relevant channel (single signalling). The reset input RE can be connected via terminal 13 or 14 (ESX10-124) or terminal 12 ((ESX10125). The integral control input IN+ of type ESX10-115 is fed in via terminal 12. Depending on the option, a potential-free auxiliary contact is also available (ESX10-103/-115)-125). Fitted with E-1048-7xx: The reference potential for the ESS20-0.. (Gnd pin 11) is also looped through and connected to the terminal elements at the sides. Actuation of the SSRPC (IN+), referenced to GND), is via the separate terminal 12 per way beside the LOAD terminal. The SSRPC has an integral auxiliary contact (break contact) used for group fault signalling. For this type of signalling, all contacts in the Modules 17plus are connected in series and are connected via two terminals (13, 14) to the terminals blocks on either side. It is possible with a test probe to contact the series connection in each module and detect possible interruptions. All internal wirings for the ground potential and the group signal are established by the sideby-side mounting of the individual modules. Fitted with ESS20-0: The reference potential for the ESS20-0.. (Gnd pin 11) is also looped through and connected to the terminal elements at the sides. All internal wirings for the ground potential and the group signal are established by the side-by-side mounting of the individual modules (centre pieces, terminal blocks). The integral make contact of the ESS20-001 (SC-SI) can be tapped at terminal 12 of the relevant channel (single signalling). The integral break contact can be tapped at terminal 12 of the relevant channel (single signalling). The ESS20-003 features an integral auxiliary contact (change-over). The contact SC-SO is used for the group fault indication. For this type of signalling, all contacts in the Modules 17plus are connected in series and are connected via two terminals (13, 14) to the terminals blocks on either side. It is possible with a test probe to contact the series connection in each module and detect possible interruptions. 2012/13 (051212) www.e-t-a.de 1 - 47
