Chint JD-8 Integrated Motor Protector 20-80A,0.25~80kW, 220V, AC-3 380V for Squirrel Cage Motor
DESCRIPTION
Advantage
• Compact installation
> Contactors to 38A and protection components are only 45mm wide
> Surge suppressor installation requires no tools and can be inserted directly into the contactor without taking up more space
> Reversible contactor is only 90mm wide, mechanical interlocking does not take up extra space, installation takes almost no time
> Starter components provide pre-wired modules for quick and easy assembly
• Highly integrated
> to 100A contactor integration 1 normally open / 1 normally closed auxiliary contact
> DC coil with built-in bidirectional suppression diode
> Reversible contactor group with built-in bidirectional suppression diode
• Safe and reliable
> The main circuit and control circuit of the control and protection components are clearly distinguished
> Mirrored contact design that meets safety standards, ensuring 10 million reliable actions
> Protective cover prevents accidental contact of the contactor
• outstanding quality
