Plug-in type circuit protector [Labor reduction]

Plug-in type circuit protector [Labor reduction]

Introducing a circuit protector that can be easily installed with a plug-in system! Just plug it into the socket mounted on the DIN rail!

This is a plug-in type circuit protector. 1. Easy to attach and detach 2. Standardization of design 3. Shortened manufacturing lead time These features help reduce labor costs! 1. Easy to attach and detach Installation is as simple as plugging it into a dedicated socket mounted on a DIN rail! It can be easily attached and detached during repairs and maintenance. 2. Standardization of design Even if there is a change in the load current value, you only need to adjust the current value of the circuit protector! By only determining the width of the dedicated socket, you eliminate the need for redesign, enabling standardization. 3. Shortened manufacturing lead time First, a standard panel is manufactured, and once the current value is determined through customization, you simply plug in the circuit protector! Since there are no changes to terminal connections due to the change of the circuit protector, it allows for time savings during manufacturing.
