RMU Mechanism FAQ
RMU MechanismTechnical FAQ
Use these checkpoints to distinguish mechanism duty and prepare a complete RMU operating mechanism enquiry.
What information is needed to select an RMU operating mechanism?
Provide the RMU application, switching function, panel general arrangement, mounting face, linkage or shaft direction, operating sequence, interlocks, control voltage, auxiliary contacts, quantity, and destination.
How do I distinguish load-switch, isolation, and circuit-breaker mechanisms?
Start with the switching duty and operating sequence. Then coordinate the drive type, earthing function, interlocks, control circuit, shaft or linkage interface, panel clearances, and the selected switch or breaker.
Can an RMU mechanism be matched to an existing panel?
Suvell can assess a compatible mechanism or adaptation from the panel layout, mounting face, shaft or linkage direction, operating clearance, interlock logic, and available mechanism photographs or drawings.
What should be included in an RMU mechanism RFQ?
Send the single-line diagram and panel drawing, switching duty, operating sequence, interlocks, control voltage, auxiliary-contact schedule, site conditions, quantity, destination, and any existing nameplate or mechanism photographs.
