About This Product

It detects abnormalities such as abnormal heat generation and shock in equipment and shuts off high voltage and large current direct current.

■POINT01 As a DC drive auxiliary equipment for EV/PHEV etc.

This is a cut-off device suitable for DC power supplies with higher voltage than conventional ones for driving auxiliary equipment such as EV/PHEV. It is possible to cut off power due to abnormal overheating of equipment without being affected by the amount of current.

■POINT02 Can cut off up to DC800V and 40A

A mechanism has been installed to reliably interrupt the arc between the contacts during the interrupt operation, making it possible to interrupt up to DC800V and 40A. We are also currently developing a product with high current specifications of 400V DC and 400A.

■Main uses

・DC drive power supplies and auxiliary equipment for EV/PHEV, etc. (battery packs, electric compressors, hot water heaters, etc.) ・Solar power generation equipment (junction box, power conditioner, etc.) ・DC power supply system

■Function

・Although it is small, it can cut off DC800V and 40A of live current. ・Attach directly to equipment overheating source to sensitively sense minute temperature changes ・Can also be operated by shock, overcurrent, or external signals

■Product features

・Detects abnormal temperatures, shocks, etc. of equipment and permanently shuts off the circuit. ・Simple structure/mechanism ・Can be set to optimal shutoff conditions ・Direct cut type using heat or impact, control type operated by external input signal
