Trailing cables, blocked motors, defective peripherals - these are all unacceptable risks in modern factory automation and process control as they are potential dangers, both to personnel and equipment. Plant designers must be careful to avoid hazardous machinery conditions in accordance with Machinery Directive 98/37/EG and to comply with the requirements of the EN/IEC 60204-1 standard "Safety of Machines, Electrical Equipment of Machines". The use of integral selective reliable protection against overloads and short circuits in electrical systems makes a significant contribution to the reduction of such risks.

The E-T-A track-mountable series 4220-T thermal-magnetic circuit breaker is ideally suited to the task and packs a powerful punch within an ultra-slim housing of just 12.5 mm. Current ratings in finely graded steps from 0.1 A through 32 A ensure overcurrent protection for loads and their supply lines can be optimised, while 5 sets of trip characteristics are available to suit different load conditions.

An integral busbar design - sophisticated, but easily manageable - serves for power distribution, configures signalling, and greatly facilitates the connection of multipole circuit breakers. Whether a single pole base unit is required, or a double pole or three pole configuration, the electrical performance and switching capability of the slim yet robust series 4220-T will never fail to impress.
