Frequently Asked Questions

What does IEEE 841 guarantee?

A tighter spec than standard severe-duty: defined temperature rise, vibration limits, bearing life, and sealing for petroleum/chemical reliability.

Is IEEE 841 the same as explosion-proof?

No. IEEE 841 is a reliability/durability standard, not a hazardous-location listing. If your area is classified, you need explosion-proof.

Why pay more for IEEE 841?

Lower failure rate and longer service life in critical process service, where downtime is far costlier than the motor.
