ABB CR463M20CJA Lighting Contactor Mechanically Held

ABB CR463M20CJA Lighting Contactor, mechanically held, is a 2-pole device with 2 normally-open (2NO) contacts designed to switch lighting loads such as fluorescent ballast and other non-inductive lighting circuits. It employs a mechanical latch with a 2- or 3-wire electronic control module to latch the contactor and remove the coil from the circuit, reducing coil losses and enabling noise-free operation. The control options include both momentary (3-wire) and continuous-supply (2-wire) configurations, with a built-in 0.4-second delay to prevent misoperation from rapid command pulses. Part of ABB’s CR463M family, it is rated for 30 A circuits and is available in standard assembled forms or enclosed configurations (including NEMA Type 12/3R oversize options) to fit different installation requirements. The CR463M20CJA can be field-configured with latch mechanisms and auxiliary contacts to tailor control logic for specific lighting-control schemes. Typical applications include switching fluorescent or HID lighting loads, signage lighting, and other commercial/industrial lighting circuits where a latched-contactor provides reliable control with reduced standby coil energy.
