Earth leakage protectors Contactor CJX22510 3P+1NO AC contactor for three phase control with DIN rail mounting This CJX22510 AC contactor is designed for three phase control applications where earth leakage protection is involved. It provides a compact, reliable switching solution with a 3pole main contact set and a 3P+1 normally open auxiliary contact, suitable for integration in control panels and protection circuits. Key features and benefits 3P+1NO normally open auxiliary contact: enables primary switching of a three phase circuit plus signaling or interlocking capability through the auxiliary contact. DIN rail mounted: designed for easy installation and removal in standard control panels and enclosures. Three phase, threepole configuration: suitable for controlling three phase loads in a compact form factor. No coil voltage supplied: coil voltage is not included with the unit, allowing you to select the appropriate coil voltage for your system. Coil voltage options: listed coil voltages include 24V AC, 220V AC, and 380V AC at 50 Hz, enabling compatibility with a range of control circuits. Color specification included: Color : 2501 Ac36v (as listed in the product title). Key specifications and attributes Model: CJX22510 Type: AC contactor Poles: 3P (3phase) with 3P+1 normally open auxiliary contact Mounting: DIN rail mounted Coil voltage: options include 24V AC, 220V AC, 380V AC at 50 Hz (coil not included) Application domain: suitable for earth leakage protection configurations and general threephase switching in control panels Color reference: 2501 Ac36v (as stated in the product title) Common use cases Control of threephase motors in protection circuits where earth leakage protection is implemented, enabling reliable switching with an integrated NO auxiliary contact for signaling. Panel installation in automation and control systems requiring a compact, DIN rail mounted threepole contactor with an auxiliary contact for control logic or interlock circuits. Integration into protective relaying schemes where a dedicated switching device is needed to isolate or connect threephase loads without a separate auxiliary contact assembly. What makes it useful Flexible coil voltage options allow compatibility with multiple control circuits without the need for multiple different parts. The 3P+1NO configuration provides both main switching capability and a builtin signaling/monitoring contact. DIN rail compatibility simplifies installation, maintenance, and replacement in standard control cabinets. Notes Coil is not supplied with the contactor; select the appropriate coil voltage for your system when . The product title includes details such as model CJX22510, 3P+1NO configuration, DIN rail mounting, and coil voltage options; ensure the coil voltage you choose matches your control circuit requirements. This description preserves the model, configuration, mounting method, and the listed coil voltage options while presenting clear, customerfriendly information to assist in decision making and integration.
