Switching Actuators N 53x

The new DIN Switching Actuators N 53x are intended for installation in

distribution boxes or small cabinets and are installed by snapping onto

a 35 mm top hat rail according to EN 60715-TH35.

All nine switching actuators have the following common features.

• The rated contact operating voltage of the switching actuators is

AC 230 V

• The products are equipped with maintenance-free terminals

• The terminals are designed for connection and through-wiring of

untreated single-core, stranded or multi-core conductors,

0.5 ... 2.5 mm². Stranded and multi-core conductors can be pushed

into the terminals without ferrules

• One relay contact per output as switching element (ON/OFF)

• Per output there is a mechanical display of the switching status via

a slide switch, which can also be used for direct manual operation

(ON/OFF switching) of the switching output

• The electronics of the devices are powered via the bus voltage

• All switching actuators are connected to the bus via bus terminal

block

• The device has a red LED for indicating activation of addressing

mode or device operation

• The housing is of plastic, N-system

• Color RAL 7035 (light grey)

• DIN rail mounted device for mounting on rail TH35 according to

DIN EN 60715

• Type of protection: IP 20

Automation functions

The switching actuators provide many control functions per output.

The basic function of the new DIN rail mounted devices is switching

with status feedback. Very powerful relays are also employed for swit-

ching capacitive loads. Via ETS conﬁguration the basic function can be

expanded by control functions (logic, timer, scenes, central switching

control), override functions (manual ON, continuous OFF, blocking,

forced control) up to diagnostic functions (counting of operating

hours and switching cycles without and with threshold monitoring).

The extent of the control, override and diagnostic functions is illustra-

ted in detail below.
