Siemens 3RV24111JA15 Motor Starter Protector Size S00

Product Description

The SIEMENS 3RV24111JA15 is a Size S00 motor starter protector (MSP) configured for transformer protection applications. Motor starter protectors combine short-circuit protection and motor overload protection in a single compact device, eliminating the need for a separate circuit breaker and overload relay. This unit is sized for the S00 frame class, making it suitable for low-amperage loads in tight panel or enclosure installations. Licensed electricians and industrial controls technicians typically specify and install this device as part of a motor control or transformer branch-circuit assembly.

This MSP is intended for transformer protection duty in industrial and commercial electrical systems. The S00 frame size targets smaller load ratings and fits directly into compatible Siemens MSP mounting and busbar systems. It is well suited for panel builders, MCC (motor control center) assemblers, and field electricians working on compact control circuits where space and branch-circuit protection requirements must both be addressed within a single device footprint.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the NEC and all applicable local electrical codes. De-energize and lock out the panel or enclosure before mounting or wiring this device. Verify that the connected load current rating falls within the MSP trip range before energizing. Do not exceed the device frame rating or use it as a substitute for a full motor protection relay without confirming the application requirements.
