Low-Voltage Replacement Circuit Breakers

Featuring Siemens WL operator

Low-voltage replacement circuit breakers provide a cost-effective way to upgrade to current technology while increasing equipment reliability and minimizing downtime. Our Low-Voltage Replacement Circuit Breakers 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 existing bus.  Our direct-rack connection eliminates the need for intermediate connections between the original bus and the new circuit breaker, therefore also eliminating potential heat and loss of efficiency due to increased resistance, and removing any additional points of failure or maintenance.  

The following circuit breakers are available as pre-engineered designs. Other manufacturer’s models and ratings can be engineered by Siemens by customer request.

Why upgrade to replacement circuit breakers?

  • Preserved investment in cubicles

  • Reduced downtime and minimal changeover time during upgrade

  • Increased reliability and performance

  • Improved employee safety

Why Siemens?

  • Direct-connect to the primary contact mitigates heat generation

  • WL operator is less prone to nuisance tripping

  • Tip modules for all applications

  • Secondary contacts mounted on front for safe, easy access

  • Remote operation and monitoring for safety

  • 24/7 support line

Safety related features:

  • Visible, ready-to-close indicator

  • Customizable interlocking, and mechanical trip indication

  • Available Siemens Dynamic Arc Sentry (DAS) provides an arc flash mitigation mode to lower th possible arc flash energy
