3120-N521-H7T1-W01D-20A is a 3120-N thermal circuit breaker/switch combination unites overcurrent protection and the function of an ON/OFF switch within a single component. The trip element is a thermobimetal. This type is ideally suited for overload protection of motors, pumps, transformers, and cables. After tripping, it can reliably, easily, and quickly be reset. The positively trip-free mechanism ensures reliable disconnection of the circuit even with the actuator blocked. Functional extension options with add-on modules for low voltage release, auxiliary contact function, remote trip or fast magnetic trip. Typical application includes medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, audio equipment, machine tools, household, hobby, and garden equipment, industrial equipment control, and medical technology.
