The contactors are suitable:

• For switching resistive loads
• For isolating systems with ungrounded or poorly grounded neutral conductors
• For system transfers when alternative AC power supplies are used
• Use as contactors which only carry current and do not have to switch in case of inductive loads – e.g. variable-speed operating mechanisms
• For switching mixed loads in distribution systems (e.g. for supplying heaters, lamps, motors, PC power supply units) with p.f. > 0.8 according to IEC 60947-4-1, test conditions for utilization category AC-1.

For a general description of sizes S00 to S2 of 3RT contactors, see "Power contactors for switching motors" > "SIRIUS 3RT contactors, 3-pole up to 250 kW".
