CB Automotive Relays

Panasonic CB Automotive Relays are compact and high-capacity DC switching automotive relays available in SPST (1 Form A) or SPDT (1 Form C) contact arrangement. These relays offer an International Organization for Standardization (Mini-ISO) terminal arrangement. The CB Mini-ISO automotive relays feature a 40A standard-type switching capacity and up to 70A @ 14V_DC high-capacity version. These relays provide a built-in resistor option for coil protection against EMF and high heat resistance up to 125°C. The CB Mini-ISO automotive relays are ideal for automobiles (cell motors, air compressors, ABS, and EPS), construction equipment, conveyor, and agricultural equipment.
