CB Series Relays

Panasonic's CB Series is a compact and high capacity DC switching automotive relay available as an SPST (1FormA) or SPDT (1FormC) contact arrangement with Mini-ISO (International Organization for Standardization) terminals. The standard type switching capacity is 40A however there is also a high capacity version rated up to 70A @ 14VDC. The sealed and flux-resistant construction types are available with either PCB or plug-in type terminals and an optional bracket mount. The CB Series offers a built-in resistor option for coil protection against EMF and high heat resistance up to 125 DegC. Both 12V and 24V coils are available as standard part numbers.
