S00 to S12 sizes up to 250 kW
S00 to S12 sizes up to 250 kW
Standard:
IEC 60947-1,EN 60947-1,
IEC 60947-4-1,EN 60947-4-1
IEC 60947-5-1,EN 60947-5-1 (auxiliary contact)
The 3RT6/3RT5 contactors are climate-tested for use in any climate conditions worldwide.
The environment in which the equipment is applied does not correspond to the standard industrial environment (as specified in EN 60721-3-3).
At the same time, it is necessary to consider the impact of the environment on product reliability and service life, and to take
corresponding protective measures. Contact Siemens Technical Support if necessary.
The 3RT6/3RT5 contactor has the "finger touch protection" function specified in EN 50274.
Add auxiliary contact
The S00 specification contactor body integrates an auxiliary contact (1NO or 1NC).
The S0 specification contactor body integrates 2 auxiliary contacts (1NO 1NC).
S2/S3 specification contactor body without integrated auxiliary contact.
S6/S10/S12 specification contactor body integrates 4 auxiliary contacts (2NO 2NC).
All size contactors can continue to be equipped with removable auxiliary contact blocks.
• S00/S0/S2/S6/S10/S12 specifications can add up to 4 contacts.
• The S3 specification can add up to 8 contacts.
For all specifications, the number of normally closed contacts shall not exceed 4.
Contact reliability
Switching at a voltage not exceeding 110 V or a current not exceeding 100 mA,
The auxiliary contact on the 3RT6/3RT5 contactor or the 3RH61 intermediate relay has a very high
of reliability.
These contacts also meet the requirements for use in solid-state circuits, with minimum on-line power at 17V.
Flow 1 mA.
Motor reference power
The motor power mentioned in the sample is the reference motor shaft output power (according to the nameplate).
Rated control voltage
All contactors are available in either DC or AC AC operated models. S6 to S12 gauge
The grid contactor coil is of the AC/DC universal type (AC 40... 60Hz,DC).
Surge suppression
The 3RT6/3RT5 contactor can provide resistance-capacitance absorption (RC), varistor, suppression two
Four types of surge suppression, diode and diode combination (zener diode and diode combination)
to suppress coil surges.
The S6 to S12 specification contactor coil has an integrated piezoresistive surge suppressor.
Note:
The use of surge suppressor to suppress the coil overvoltage will cause the contactor normally open contact NO to break.
delay and normally closed contact NC turn-on delay (the suppressor diode will increase the delay by 6 to 10
times, the diode combination will increase the delay by 2 to 6 times, and the varistor will increase the delay by 2
5 ms）。
