Phoenix Contact Circuit Breaker Bases & Accessories
Phoenix Contact circuit breaker accessories are device modules, optional attachments, and field-installed components used to add control, signal feedback, and advanced switching functions to Phoenix Contact circuit breakers for industrial automation, control, and OEM equipment protection. These accessories provide standardized interface points for remote tripping, alarm indication, and integration with auxiliary signals in machine-level or panelboard-level installation.
These UL-rated accessories mount directly to Phoenix Contact circuit breakers, reducing installation time and helping to maintain compact wiring in control panels or distribution nodes. By adding switch signal status indication, alarm detection, or a remote breaker trip function, operators can enhance the safety and monitoring of their automated circuits. For OEM panels, machine builders, and process equipment suppliers specifying Phoenix Contact circuit breakers, these accessories offer a convenient upgrade path to advanced control options without sourcing custom or third-party field kits. The modular accessory approach ensures a factory-matched fit to the breaker body and guarantees accessory compatibility with breaker series for fast installation and commissioning.
FAQs – Phoenix Contact Circuit Breaker Accessories (Top 5% SEO)
What accessories are available for Phoenix Contact circuit breakers?
Phoenix Contact offers accessories such as auxiliary contacts, alarm contacts, shunt-trip modules, and remote-signaling devices — all designed to expand breaker function beyond overcurrent protection and support control, monitoring, and emergency shutdown use cases. Phoenix Contact+2RS Components+2
What does a shunt-trip accessory do?
A shunt-trip accessory lets a circuit breaker be tripped (opened) remotely via an external electrical signal; this is useful for emergency shutdowns, fire-alarm integration, or automated safety control systems, allowing quick disconnection without manual intervention. Phoenix Contact+1
When would I use an auxiliary contact or alarm contact on a Phoenix breaker?
Auxiliary or alarm contacts provide remote status feedback — showing whether a breaker is open or closed, or indicating a trip event. This lets automation systems, SCADA, or building-management systems monitor circuit status and trigger alerts if a breaker trips or is manually opened. Phoenix Contact+1
Are Phoenix Contact breaker accessories compatible with both TMC 7 and TMC 8 series breakers?
Yes — many accessories such as shunt-trip modules, auxiliary and alarm contacts are designed to be compatible with both TMC 7 (UL 1077 supplemental protectors) and TMC 8 (UL 489 branch-circuit breakers) series, giving flexibility across control- and power-circuit applications.
How do Phoenix Contact breaker accessories improve system safety and reliability?
By enabling remote shutdown, status signaling, and integration with control or alarm systems, Phoenix Contact breaker accessories help prevent unsafe restart conditions, enable fast emergency response, and improve visibility into power distribution — reducing downtime and enhancing overall safety and compliance.
