Important notes at the end of this document.

Notes:

1

The recommended cross section refers to pure copper. In other cases it must be matched to actual current, conductor

material properties and operation temperature (see: Cautions and warnings).

2

Detection time 10 µs: micro-openings ≤ 10 µs may occur between main contacts

3

Referring to IEC 60068-2-27

4

Referring to IEC 60068-2-6

5

Referring to IEC 60068-2-64

6

Freezing or condensing must be avoided.

7

Valid for base-model without accessory, other configurations will lead to deviations.

8

The specified values apply to unused contactors acc. to IEC 61810-1.

9

Referring to IEC 60947-4-1, 6000 operations make & break

10 Referring to IEC 60947-4-1, 50% of operations in positive and 50% in negative direction (see: Cautions and warnings)

11 Detection limit 10 mA

12 Measured at rated control voltage UC including contact bouncing time.

13 Specified referring to JIS C 5442 (temperature 15 °C to 35 °C, humidity 25% to 85% RH).

14

End of life is reached when insulation resistance is < 50 MΩ at 1000 V.

15 Duty cycle 50%, cycle duration 1 s, value represents B10 life time acc. to Weibull analysis.

16 Duty cycle 1%, cycle duration 600 s.

17 No fire and no explosion will occur after this break

18

Tested with resistive loads with τ ≤ 1 ms

19

Tested for maximum break at 1000 V, 450 A with τ ≤ 0.3 ms.

20 Tolerance ±10% at thermal equilibrium

21 For „make & break life curves“ duty cycle is 10% and cycle duration is 6 s. For “break-only life curves” duty cycle is 1%

and cycle duration is 600 s.

Cautions and warnings



To guarantee a satisfying performance of this contactor in the application we strongly recommend

to implement redundancy, take measures to prevent the spread of fire, take the possibilities of

malfunction into account, and perform regular maintenance.



It is also required to always use a suitable backup fuse for the contactor.



It is not allowed to use the contactor outside of the parameter range specified in this datasheet.

This also includes temperature and humidity. Overloading the contactor may destroy the

component.



The lifetime is dependent on several factors: e.g. load type, driving circuit and ambient conditions.

We recommend checking the performance of the part under actual conditions.



For capacitive loads, the inrush current through the contactor should not exceed the specified

limit of the estimated make & break life curves, otherwise tack welding and permanent failure will

occur.



Break of inductive loads with τ > 1 ms will shorten the lifetime and failure may occur.



In the event of a break under inductive load, the voltage at the connection terminals of the

contactor must not exceed the nominal operating voltage by more than 10 %.



For continuous high current operation, make sure that the temperatures of the connection

terminals do not exceed 130 °C by selecting an appropriate connection cable cross section or

active cooling.



The main connections of the contactor also act as a heat sink. Please ensure that the connection

surface area is fully covered with a matched cable lug or busbar and that the connection hole in

the busbar is according to DIN ISO 20273 (middle clearance).
