Product details

The 3RT2017-1UB42: The 24 VDC coil (rated value 24 V) operates within a 0.8 to 1.1 × rated voltage range, meaning the coil pulls in reliably between 19.2 V and 26.4 V DC — a tolerance that covers most 24 VDC control supplies even under brownout conditions.

Switching frequency and contact ratings for motor duty

Mechanical endurance is 30,000,000 operations typical — this is the mechanical life before wear on the armature and spring mechanism, not the electrical contact life which depends on switching current and duty cycle.

Frequently asked questions

What is the auxiliary contact rating at 24 VDC for the 3RT2017-1UB42?

These are the specific DC switching limits — do not interpolate between them.
