Allen-Bradley 700-NA20 Low Voltage AC Contactor

The Allen-Bradley 700-NA20 Low Voltage AC Contactor is a replacement contact cartridge in Allen-Bradley’s 700-series modular control line. It provides the main switching contacts used to control low‑voltage AC circuits that power inductive loads in industrial equipment. Designed to be used with a compatible 700-series frame and accompanying accessories, the NA20 cartridge forms the heart of a complete contactor assembly by providing the essential conductive path that closes and opens under control of an AC coil. Energized by a low‑voltage AC coil, this cartridge is intended for panel-installed control systems where serviceability matters, allowing the contact pair to be replaced without discarding the entire assembly. Before installation, verify compatibility with your frame size, coil voltage, and contact configuration to ensure safe, code-compliant operation. The 700-NA20’s role is to interface with a control supply and control circuitry to perform switching in machines such as conveyors, fans, pumps, and other loads that require reliable, modular contactor functionality.
