Fuji Elect-CP31,CP31D,CP32D circuit protectors

　


Description

The CP31 and CP32 have a similar functions to a molded case circuit breaker and they can be used for normal switching ON and OFF operations while breaking both overload and short-circuit currents. They are available in two time-current versions¡Xan instantaneous and a time-delay version. A suitable type should be selected to match the thermal and permissible current requirements. These are recommended for sequential control circuits, motor control circuits, solenoid-operated valves, heaters and solid-state applications.

　


Features

● Excellent arc interruption Since the arc extinguisher uses a loop blow-out system the arc is rapidly extinguished.
● Highly visible handle indication ON shows red and OFF or TRIP blue.
● When positioned at ON the operating handle is completely housed inside the molded case and does not protrude. This helps to prevent erroneous operation.
● Trip-free mechanism
● Also available with auxiliary switch SPDT.
● Two time-current versions - instantaneous operation and a time delay type. Select the model best suited to your protection needs.
● CP31D and CP32D types are of front and rail dual mounting.

　


Time-delay tripping type

　


Typical applications

These CP31 and CP32 protectors are used for normal on-off switching of the power supply while also providing overload protection of the load circuits.

　


Time-delay tripping type

● Control circuits
● Solenoid valves and motor circuits
● Heater circuits

　


Instantaneous tripping type

● Semiconductor circuits
● SCR (Silicon controlled rectifier) and triac circuits
● Computer peripheral equipment
