General Electric CR305B102 Magnetic Contactor

GE CR305B102 Magnetic Contactor is a Size 0, 3‑Pole device with a 120V coil designed to switch power in electrical control circuits. The coil is energized by a control circuit, causing magnetic force to close the three main contacts; when the coil is de‑energized, springs return the contacts to the open position. This makes it an electrically operated switch for remote control of line loads in panels and equipment. The CR305B102 designation identifies the GE part number and its Size 0 frame, providing a compact option for panel installations where multiple conductors must be switched in one device. With a 3‑Pole configuration, it can manage three conductors within a single unit, suitable for controlling line loads in 120V control environments and integration with standard control relays in electrical systems. Install and wire per applicable electrical codes.
