Product details

S00 frame, 110 V DC coil, spring-clamp terminals

The 3RT2017-2BF41: The coil draws a rated value of 110 V DC with an initial pickup threshold of 0.8 and a full-scale hold of 1.1, meaning the coil reliably pulls in at 88 V and stays sealed up to 121 V.

Temperature range and lifecycle

The typical mechanical life of the contactor is 30,000,000 operations, which is the wear limit of the spring-clamp mechanism and armature, not the contacts.
