Contactor Relays 3TH30
Reliability and safety are pre-requisites in the choice of the control contactor. Siemens 3TH30 contactor
relays satisfy these criteria and thus offer the right choice to the customer.
Applications
3TH30 are used in control circuits for switching and signaling
purpose. Also they are used for interfacing with the electronic
circuits.
Standards
Contactor relay conforms to IS /IEC 60947-5-1.
They also carry CE mark.
Range
Air break contactor relays are suitable for 10A, (AC15/AC14 rating)
at 240V AC and 10A, (DC13 rating) at 24V DC.
Benefits and features
Flexibility
• Choice of auxiliary contacts
3TH30 contactor relays comes with 4 contacts as a basic unit
(4NO, 3NO+1NC, 2NO+2NC). However the contacts can be
extended upto 8 contacts by adding maximum 4 auxiliary
contact blocks to this basic unit. This offers flexibly in selection
and configuration.
• Choice of mounting
3TH30 can be mounted on 35mm DIN rail and they are also
suitable for screw mounting.
Long Life
Superior design of current carrying parts, contact system and the
magnet system increases the reliability which also results into
higher electrical and mechanical endurance.
High reliability
• Double Break Parallel Bridge contact mechanism
This mechanism is available with 3TH30. Such contact
mechanism ensures reliable contact at low voltage and low
currents (5mA at 17V DC). It also offers unmatched reliability
as well as capability to integrate directly into PLC or
instrumentation circuits.

Auxilary Contacts
User friendliness and safety
• Positively driven contacts
3TH30 auxiliary contactors satisfy the conditions for positively
driven operation between NO and NC contacts. NO and NC
contact do not close at the same time. This is extremely
important when they are used in safety circuits of critical
applications. This ensures operator safety even during
abnormal condition.
• SIGUT Termination
– Figure touch proof terminals
It protects against accidental contact with live parts which
ensures operator safety.
– Funnel shaped cable entries
Reduce wiring time by facilitating quick location of the
connecting wire.
– Cable end-stop
It decides the insertion depth of the connecting wires. Since
the insertion depth is predetermined, insulation of the cable
can be cut accordingly and the possibility of insulation
getting inadvertently caught under the terminal is avoided.
– Captive Screws
This feature prevents the screws from falling down thereby
facilitates the wiring. Hence, the auxiliary contactors are
delivered with untightened terminals. This eliminates the
operation of untightening terminals before wiring.
– Lug less termination
This feature helps in reducing the termination time.
