NF Series Intermediate Relays

Effective control enables continuous operation

The NF Series intermediate relays are based on AF technology, offering multiple advantages over traditional technology with electronically controlled coils. With ABB's extensive product range, each application achieves optimal configuration.

Key Advantages

? Significantly streamlined product models help optimize logistics and reduce management costs

? The same model is suitable for almost all global applications; global technical support is available

? Coil energy consumption reduced by 80%, greatly saving energy costs

? AF technology effectively handles instantaneous control voltage drops or losses, ensuring normal operation

Key Features

? Available in 4-pole and 8-pole models; 8-pole models include permanently fixed 4-pole auxiliary contacts

? Supports screw, spring, and ring connections

? Built-in surge suppressor

? NF33/11 and NF51/11 models feature both traditional and advanced contacts

? Snap-on accessories for easy use

? Mechanically interlocked contacts
