• Saves material costs
• Reduces installation costs
• Enables fast connections
• Permits vibration-resistant connections
• Enables maintenance-free connections
• Enables fast connections
• Permits vibration-resistant connections
• Enables maintenance-free connections
• Allows the use of the relays at high temperatures
• Prevents premature tripping
• Allows compact installation of the controlgear
• Simplifies configuration
• Enables space to be saved in the controlgear
• Provides safe protection for the loads even after
• Reduce the number of variants
• Minimize the engineering outlay and costs
• Minimize storage overhead, storage costs,
• Enables solutions for very fast starting motors
• Enables heavy starting solutions
• Reduces power consumption and energy costs
• Minimizes temperature rises of the contactor and
• Direct mounting to contactor saves space, even
operating personnel in the event of short-circuits
due to insulation faults or faulty switching
operations
space-saving direct mounting
(only one point of contact)
and fast).
without derating
cabinet without space between the units/load

years of use in severe operating conditions
tied-up capital
requiring special protection (e.g. Ex motors)
(up 98% less power is used than for thermal
overload relays).
controlgear cabinet – in some cases this may
eliminate the need for controlgear cabinet cooling.
for high motor currents (i.e. no heat decoupling is
required).
