Compact plug-in circuit breaker for automation
15 May 2012
E-T-A Circuit Breakers has introduced a compact thermal-magnetic circuit breaker, increasing its plug-in mounting product range for automation in industrial and buildings applications. The single or double pole E-T-A 2216-S provides protection against overcurrent in a control cabinet or in a local area. And with an overall width of 12.5mm and a depth of only 70mm, the unit occupies very little space in the control cabinet.
The new circuit breaker is suitable for side-by-side, snap-in installation in new E-T-A rail-mountable sockets - the 80plus (with screwless PT connecting terminals) or the 81plus (with screw terminals). The sockets allow time-saving power distribution and signalling by means of plug-in type jumpers. In addition, coding pins ensure ease of allocation between breaker and socket according to the “lock-and-key principle”. The dimensions of type 2216-S with socket meet the requirements of DIN 43880 (built-in equipment for electrical installation).
Single or double pole circuit breakers are available in different current ratings from 0.5A to 16A. Auxiliary contacts are optionally available (change-over contacts) for initiating alarm circuits and subsequent switching operations or for status indication of the main contact.
Type 2216-S is suitable for voltages up to 240Vac and for up to 50Vdc (single pole version) or 80Vdc (2 pole version). Three different trip curves are available: the instantaneous F1 curve for dc circuits corresponds to the standard A characteristic of circuit breakers; the fast trip curve F2 and the medium delay curve M1 are suitable for both ac and dc applications. The F2 curve corresponds to trip characteristic B and the M1 curve corresponds to the C characteristic to IEC/EN 60898/1 (DIN VDE 0641-11).
