Solid Industrial Construction

The build quality feels durable and professional. The adjustment dial moves smoothly, and the reset mechanism works reliably. I appreciate the IEC *****-4-1 compliance cause it gives confidence when working on industrial installations. Definitely not a lightweight component.
