Type overview
Type
N 535D51
Characteristics
Switching actuator N 535D51 can switch eight mutually independent groups of electrical consumers via
eight potential-free outputs.
The switching actuator can switch resistive loads (e.g. electric heater, incandescent lamps), inductive
loads (e.g. motor, low-voltage halogen lamps with upstream wound transformer) or capacitive loads
(e.g. low-voltage halogen lamps with upstream electronic transformer).
The device is suitable for switching loads with high inrush current spikes, particularly for fluorescent lamp
loads (AX) as per DIN EN 60669-2-1.
The permissible lamp loads are listed in the "Technical data" section.
The device is a rail-mounted device in N dimension for installation in arrangements and is installed on
35-mm rails as per standard IEC 60715. The switching actuator is connected to the bus connection with
a bus terminal block. The power supply is supplied via the bus voltage (no additional power voltage is
required). Every actuator output has a potential-free relay with switch position display. Via the relay, the
switch position can be changed with a tool.
Every actuator output has one terminal each for the supply voltage (rated operating voltage AC 230 V)
and the switched load.
The maintenance-free terminals are for connecting solid, fine-stranded and stranded conductors with
conductor cross-sections from 0.5 to 2.5 mm
into the terminals without ferrules.
The terminals have two terminal connections each, allowing, for example, the looping through of the
supply voltage from one actuator channel to the next.
Each of the outputs (relays) can be assigned different functions depending on the application, i.e.
switching actuator N53x consists of the device (hardware) and the application program (software).
