The 45 mm width and 58 mm height keep the footprint compact for dense cabinet builds.
This contactor is rated for different switching frequencies depending on the load category. At AC-3 (motor starting / running), it handles up to 750 switching operations per hour; at AC-4 (plugging / inching), the rate drops to 250 operations per hour. The AC-1 resistive load rating is 1 000 operations per hour. These numbers define the thermal duty cycle — exceeding them accelerates contact wear, especially on inductive loads. The main contacts are rated for 20 to 12 A depending on the specific load and voltage, placing this unit in the lower end of the Size S00 power range. For auxiliary contacts, the switching capacity varies by voltage: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. The 400 V rating is notable — it confirms the auxiliary contacts can switch control circuits on 400 V line-to-line without derating.
Installation and environmental limits
These are fast enough for most motor control circuits but should be verified against any safety-rated off-delay requirements.
