3RB3036 overload relay equipment
Position digits
①
Connection for contactor mounting:
In terms of their electrical and mechanical features and their design,
these pins are perfectly compatible with the 3RT2 contactors for the
direct mounting of overload relays. Stand-alone assembly is also an
option (in some cases in conjunction with a stand-alone assembly
module).
②
Switch position indicator and TEST function for wiring:
Indicates a trip and facilitates testing of the wiring.
③
RESET button
A device set to manual RESET can be reset locally by pressing the
RESET button. On the 3RB31 an electronic remote RESET is
integrated.
④
Electronics test (device test):
Enables a test of all major device components and functions.
⑤
Control circuit terminal (removable):
A screw-type or spring-loaded system can be used to connect the
control circuit terminal.
⑥
Main circuit terminal:
The main circuit can be connected using either the screw-type
connection system or through-hole technology with straight-through
transformer.
⑦
Selector switch for manual/automatic RESET and RESET button:
The slide switch is used to choose between manual and automatic
RESET.
⑧
Motor current setting:
The large rotary button provides an easy means of setting the device
to the rated motor current.

A sealable transparent cover can be optionally mounted on the solid-state overload relays in
the sizes S00, S0 and S2 (Accessories (Page 83)). It stops the motor setting being tampered
with.
Auxiliary contacts
3RB30 solid-state overload relays are equipped with an NO contact for the "tripped"
message and an NC contact for disconnecting the contactor.
