Type Description

N 360 N 360 peak load limiters

• For peak load limitation in plants with tariff-based power

measurement

• Value of an energy pulse configurable in watthours

• Configurable peak load limit of 30... 1000 kW, with configurable

warning limit of 25 ... 1000 kW

• Configurable measuring period of 15, 30 or 60 minutes for the

calculation of the power mean value

• Configurable cycle time of 15, 30, 60, 120 or 240 seconds for

the load extrapolation interval

• Up to 120 loads assignable to peak load limitation

• State monitoring and switching of loads over the KNX

• With parameters assignable per load

• Power consumption of the load

• Turn-off priority (1 ... 10)

• Release/locking of load

• Minimum make time

• Minimum break time

• Maximum break time

• Number of permissible switching cycles in 24 h

• Transmission of extrapolation data via KNX after each

extrapolation

• Transmission of statistics data via KNX at the end of each

measuring period

• 3 LEDs for display of availability (operational voltage), of an

impending exceeding of the maximum value and of a

missing synchronization pulse

• 5 LEDs for display of the current time interval within the

measuring interval

• 8 LEDs for status indication of the first 8 loads

• Inputs for connection of energy pulses generated by utility

company counters and for connection of synchronous

pulses and high/low-tariff contacts

• Electronics powered over an integrated power supply unit for

230 V AC

• Integrated bus coupling units

• Bus connection over bus terminal and contact system to

data rail

• Modular installation devices for mounting on

TH35 EN 60715 mounting rail

• Width 4 MW (1 MW = 18 mm)
