Legacy RL Low Voltage Power Breakers

WL Power Circuit Breakers

Siemens continues to manufacture RL and LAC circuit breakers to support the demand for replacements and extensions of existing low voltage lineups.

Our commitment to quality, performance, and reliability of the RL and LAC breakers remains our focus as it has since 1961. The RL family of low voltage breakers is designed for up to 600v service whilst replacement LAC breakers are designed to fit into existing switchgear without modifications, offering interchangeability with existing type LA breakers from 1961 to present.   Furthermore, they are both available in fused or unfused applications.

RL Low Voltage AC Power Circuit Breaker​

Exact duplicates are provided with no modifications required to install.

 

Replacement RL breakers are now supplied with the serial number visible from the front cover, eliminating the need to open the panel door. Electrically operated, manually operated, or a combination of electrically and manually operated breakers are available. The following designations are available:

RL – Standard Interrupting​

RLE – Extended Interrupting​

RLF – Fused Type​

RLX – Extended Interrupting (legacy)​
