According to E-T-A ElectroTechnical Applications , trailing cables, blocked motors, defective peripherals are some of the risks in modern factory automation and process control as they can be dangerous to both 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 reduces such risks.

The E-T-A track-mountable series, 4220-T thermal magnetic circuit breaker, comes with a slim housing of 12.5 mm.

Current ratings in graded steps from 0.1A through 32A ensure overcurrent protection for loads, optimising their supply lines. Five sets of trip characteristics are available to suit different load conditions.

An integral busbar design, serves for power distribution, configures signalling, and facilitates the connection of multipole circuit breakers. The 4220-T thermal magnetic circuit breaker is suitable for a single pole base unit and a double pole or three pole configuration.
