Safety Contactor · 18A AC-3, 3-Pole, 120V AC Coil, 1NO+1NC Aux · FVNR Safety Design · Noark Electrical EX9CA1811G7
What this product is for
The EX9CA1811G7 is a safety contactor for machine safety and motor control circuits. It is built for applications that need a 3-pole contactor with a 120V AC coil and mechanically linked auxiliary contacts for status feedback in safety-related control systems.
Use for
- Safety relay and safety circuit outputs
- Motor starters and FVNR control panels
- HVAC equipment control panels
- Industrial automation cabinets
- Panel builds requiring mirror-contact feedback
Avoid for
- Applications needing a different coil voltage such as 24V DC or 240V AC
- Loads above the contactor's 18A AC-3 rating
- Installations requiring a reversing contactor assembly
- Standalone safety relays where a contactor is not the correct switching device
Best for
Best for electricians, OEM panel builders, and maintenance teams specifying a compact safety contactor for 120V AC control circuits. It suits machine panels and motor control assemblies where positively guided mirror contacts help confirm contact state.
Installed in
Typically installed on 35 mm DIN rail or panel mount inside industrial enclosures, automation cabinets, and commercial equipment control panels.
Why this product exists
Safety contactors are used where standard switching is not enough. The Ex9CA design adds mechanically linked mirror contacts to support safer control logic and feedback monitoring in safety-related parts of a control system.
Compared with similar products
Compared with a standard IEC contactor, this Ex9CA safety contactor is intended for safety function applications and includes mirror-contact functionality. Compared with higher-amp models in the same family, this 18A version is commonly selected for smaller motor loads and compact control panels. As typical guidance only, contactor selection should also consider motor horsepower, duty, control voltage, and local code requirements. Actual suitability depends on the full circuit design and installation conditions.
