The door-coupling rotary operating mechanisms consist of a actuator, a coupling driver and a 130/330 mm long extension shaft
(6 mm x 6 mm).
The door-coupling rotary operating mechanisms are dimensioned for degree of protection IP64. For UL/CSA applications, they are
approved for Enclosure Types 1, 3R and 12. The door interlocking prevents accidental opening of the control cabinet door in the
ON position of the motor starter protector. The OFF position can be locked with up to three padlocks.
With the optional 3RV2926-0Q tolerance compensation, an offset can be compensated when installing the door-coupling rotary

Door-coupling rotary operating mechanisms for harsh conditions
The door-coupling rotary operating mechanisms consist of a actuator, a coupling driver, an extension shaft of 300 mm in length
(8 mm x 8 mm), a spacer and two metal brackets into which the motor starter protector/circuit breaker is inserted.
The door-coupling rotary operating mechanisms are designed to degree of protection IP65. For UL/CSA applications, they are
approved for Enclosure Types 1, 3R and 12. The door interlocking reliably prevents opening of the control cabinet door in the
ON position of the motor starter protector/circuit breaker. The OFF position can be locked with up to three padlocks.
Laterally mountable auxiliary releases and 2-pole auxiliary switches can be used.
The door-coupling rotary operating mechanisms thus meet the requirements for isolating functions according to IEC 60947-2.
With the optional 3RV2926-2Q tolerance compensation, an offset can be compensated when installing the door-coupling rotary
operating mechanism for harsh conditions.

One contact system always signals tripping irrespective of whether this was
caused by a short circuit, an overload or an auxiliary release. The other
contact system only switches in the event of a short circuit. There is no
signaling as a result of switching off with the actuator.
In order to be able to switch on the motor starter protector again after a short
circuit, the signaling switch must be reset manually after the error cause has
been eliminated.
The overall width of the signaling switch is 18 mm.

Enclosures for surface mounting
All enclosures are equipped with N and PE terminals. There are
two knock-out cable entries for cable glands at the top and two
at the bottom; also on the rear corresponding cable entries are
scored. There is a knockout on the top of the enclosure for indi-
cator lights that are available as accessories.
In the enclosure for motor starter protector size S2 there is also
room for the laterally mounted auxiliary release. There is no pro-
vision for installing a motor starter protector with a signaling
switch.
The molded-plastic enclosures of the size S2 motor starter pro-
tectors are fitted with a rotary operating mechanism.
The enclosures can be supplied with either a black rotary oper-
ating mechanism or with an EMERGENCY-STOP rotary operat-
ing mechanism with a red/yellow knob.
The rotary operating mechanisms can be locked in the Open po-
sition with up to 3 padlocks.
