The CKDC2 Series CKDC2B12/P7 contactor is rated for 50/60 Hz AC circuits up to 690V and DC circuits up to 440V. In AC3 service at 380V it supports remote switching and frequent motor starting and stopping up to 85A circuit current.

The contactor accepts auxiliary contacts or air-delay contacts and supports AC and DC coil control, electric and pneumatic timing modules, and reversible coil terminals. Combined with a thermal overload relay it forms a complete electromagnetic motor starter.

Key Features

• Main contacts: 3NO + 1NO auxiliary contact
• Coil voltage: 230VAC 50/60Hz for direct mains connection
• Accepts auxiliary contact or air-delay contact add-ons
• Compatible with electric and pneumatic timing modules
• Reversible coil terminals — power or load terminal orientation

Product Benefits

• 12A AC3 rating covers frequent motor start/stop cycles without derating
• Works across AC (up to 690V) and DC (up to 440V) systems from a single unit
• Combined with a thermal overload relay it provides full electromagnetic motor-starter protection
• Space-saving rail-mount design with modular expansion via add-on contacts
• Reversible coil terminal simplifies panel wiring in restricted cabinet layouts
