AB 100C12EJ10 is an IEC-standard contactor produced by Allen-Bradley (a brand of Rockwell Automation), mainly used for frequent on/off control of AC circuits in industrial automation systems (e.g., motor starting, load switching). Below are its detailed specifications:
- Rated Operating Current (AC-3): 12A(AC-3 is the IEC standard for "squirrel-cage motor starting, running, and stopping" — the most common scenario for this contactor.)
- Coil Voltage: 230V AC (50/60Hz, universal frequency design for global compatibility)
- Power Rating (at AC-3):
- 4kW @ 230V AC
- 7.5kW @ 400V/415V AC
- 11kW @ 690V AC(Matches the power requirements of small-to-medium squirrel-cage motors.)
- Main Contacts: 3 Normally Open (NO)(Standard 3-pole design for 3-phase AC circuits, suitable for 3-phase motor or 3-phase load control.)
- Auxiliary Contacts: None (basic model; auxiliary contacts need to be added separately if signal feedback/control is required)
- Mounting Method: 35mm DIN Rail Mounting(Complies with IEC 60715 standard, the most common rail type in industrial control cabinets for easy assembly and wiring.)
- Connection Type: Screw-Terminal Connection
- Conductor Size: 16–10 AWG (solid/stranded wire, with wire ferrules recommended for stranded wire to ensure stable contact)
- Torque Requirement: 0.8–1.1 N·m (to prevent loose connections or terminal damage)
- Dimensions (Approx.):
- Height: ~85mm; Width: ~45mm; Depth: ~75mm(Compact design, saves space in control cabinets.)
- Temperature Range:
- Operating Temperature: -25℃ to +60℃ (suitable for most industrial workshops and indoor control environments)
- Storage Temperature: -55℃ to +80℃ (supports long-term storage in harsh warehouse conditions)
- Humidity Resistance: 5%–95% RH (non-condensing, prevents moisture-induced electrical faults)
- Protection Degree: IP20 (front panel; prevents fingers or small objects from entering, suitable for installation inside closed control cabinets)
Complies with global safety and electromagnetic compatibility (EMC) standards, ensuring use in different regions:
- China: CCC (GB standard compliance)
- Europe: CE (EN 60947-4-1 standard)
- North America: UL/cUL (UL 508 standard for industrial control equipment)
- International: IEC 60947-4-1 (global IEC electrical safety standard)
- Auxiliary Contact Expansion: This model has no built-in auxiliary contacts. If you need signal functions (e.g., "contactor on/off status feedback"), match it with Allen-Bradley’s 100S series auxiliary contact blocks (e.g., 100S-C09).
- Coil Voltage Confirmation: The coil is fixed at 230V AC; do not connect to other voltages (e.g., 110V AC, 380V AC) to avoid coil burnout.
- Maintenance: Regularly check terminal tightness and contact wear (replace if contacts are oxidized or pitted) to ensure reliable operation.
