Siemens 3RV27111DD10 Thermal Magnetic Circuit Breaker

Product Description

The SIEMENS 3RV27111DD10 is a thermal magnetic circuit breaker listed to UL489, sized for S00 frame applications. It provides overcurrent and short-circuit protection in motor branch circuits and control panel installations. The UL489 listing confirms it is rated for branch-circuit protection, not just supplemental protection. Licensed electricians and panel builders install this device in industrial control panels, motor control centers, and machine tool enclosures where reliable, code-compliant protection is required.

This circuit breaker is suited for use in compact industrial control panel builds where S00 frame dimensions are specified. The S00 frame size makes it appropriate for space-constrained applications such as motor starters, drives, and automation equipment panels in both light manufacturing and process control environments. It ships one unit per pack.
