New compact E-T-A plug-in type circuit breaker

Thermal-magnetic circuit breaker for automation in industrial applications and buildings

E-T-A Circuit Breakers, quality designer and manufacturer of a broad range of electro-mechanical and electronic products for circuit protection, has introduced a new compact thermal-magnetic circuit breaker type 2216-S, increasing its plug-in mounting product range for automation in industrial and buildings applications. The single or double pole E-T-A 2216-S enables cost-effective integration of protection against overcurrent in a control cabinet or in a local area.
With an overall width of 12.5mm and a depth of only 70mm, the type 2216-S occupies very little space in the control cabinet. The new circuit breaker has specifically been designed 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 the DIN 43880 standard (built-in equipment for electrical installation).

Three characteristic curves for perfect adjustment to loads and lines

The single or double pole circuit breakers E-T-A 2216-S 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 has been designed for voltages up to 240 V AC and for up to 50 V DC (single pole version) or 80 V DC (2 pole version). Three different trip curves are available, allowing perfect adjustment to the load and line requirements. 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). The new circuit breaker type 2216-S will carry approvals to IEC EN 60934, UL 1077 and UL 508 and is therefore suitable for international use.

E-T-A designs and manufactures a broad range of electro-mechanical and electronic products for circuit protection, control and instrumentation, including the world’s largest range of circuit breakers for equipment (CBEs). E-T-A equipment is specified and installed by a wide variety of industrial OEMs and end-users, with key markets including air, sea and land transport, process control, computers and communications, medical equipment, domestic appliances, machine tools and robotics.

E-T-A is an international company with headquarters in Altdorf, Germany and production facilities in several other countries, together with marketing, sales and technical operations throughout the industrial world. Its European, North American and Far Eastern markets are served by some 1,500 employees.
