Low-voltage retrofit circuit breakers
Featuring Siemens' innovative direct-rack design
Low-voltage retrofit circuit breakers provide a cost-effective way to upgrade to current technology while increasing equipment reliability and minimizing downtime. Our low-voltage retrofit solutions utilize the proven Siemens' WL circuit breaker for the core operator, main contacts, and accessories, and are designed so that the primaries connect directly to the original bus.
Our innovative direct-rack design eliminates the need for intermediate connections between the original bus and the new circuit breaker. This design eliminates additional heat generation and loss of efficiencies due to increased resistance that can be caused by intermediate connections, thus removing potential points of failure and maintenance.
At Siemens, "legacy" doesn't mean we stop supporting you or your product. The RL circuit breaker is still alive, well, and fully supported.
In addition to our state-of-the-art retrofit solutions, Siemens continues to manufacture the Siemens type RL circuit breaker, supporting the demand for replacement circuit breakers for existing low voltage type R switchgear lineups. Our commitment to quality, performance, and reliability of RL circuit breakers has remained a priority since 1981. The RL family of low voltage power circuit breakers is designed for up to 600 V service and are UL certified.
