The PC-Series, AC Residual Current Circuit Breaker with Overcurrent Protection (RCBO), combines the ground fault protection of a GFCI with the familiar overcurrent tripping characteristics of a normal circuit breaker. It detects lower level ground faults that do not trip ordinary circuit breakers, but could lead to shock hazards and fires in installations near water. Innovative features include status LED indicators distinguishing if a breaker is closed with line voltage present, or has opened due to leakage current, or has opened due to over current, or is closed with no line voltage present. It also offers an optional Hot/Neutral reversal detection and protection.

Product Highlights

  • Meets latest UL 943 standards
  • GFCI Self-test auto-monitoring & end-of-life indication
  • Integrated push-to-reset button
  • Overload, short circuit and ground fault protection in a single package
  • Status LED indicators
  • Single circuit solution for AC branch ground fault protection
  • Optional panel seal

Typical Applications

  • Generators

  • Marine
  • AC main ground fault protection for a boat's entire AC electrical system

Carling Technologies TB-Series Tandem-Pole


The TB-Series is a space saving, tandem pole circuit breaker specifically designed to fit a two pole breaker into a one rack unit, making it ideal for datacom and PDU applications.

The TB-Series is designed with a common trip linkage ensuring if one pole trips, the tandem pole simultaneously trips. It also features a trip-free mechanism, a safety feature making it impossible to manually hold the contacts closed during overcurrent or fault conditions. TB-Series options include available handle guard to prevent inadvertent actuation and an auxiliary switch.

2 poles; ratings from 0.10 to 20 amps, up to 120/240VAC; UL 489 Listed, TUV, IEC/EN 60947-2.

Electric Power Grid Upgrade

Recently, an electric power company selected a 2 pole, 15 amp, UL489 listed CX-Series (CX2-B0-12-615-2DA-13G) as the hydraulic magnetic breaker to use in substation racks as an effort to improve its networking capabilities.  The goal is to create a smart grid by converting their existing remote terminal units from serial communications protocol to Internet protocol. Using this approach with an Ethernet connection allows it the flexibility to interface faster and in real time with corporate servers and thus establishing a smarter service grid.

Industry Trend

Further, "under the American Recovery and Reinvestment Act of 2009, the Department of Energy was charged with investing $4.5 billion to modernize the U.S. electric grid through the deployment of smart grid technologies" (Hoffman, Patricia -Assistant Secretary DOE). This creates a real opportunity for increased sales of the CX-Series circuit breaker for this type of application.

The CX-Series circuit breaker features an innovative configuration that allows the breaker to safely handle high amperage and high DC voltage applications in a compact package. By using a magnetic flux boosting terminal configuration, a strong magnetic field is created thus motivating the arc into an enhanced arc chamber.

Permanent magnets combined with the upper and lower arc runner increase the magnetic blow out force and aid in motivating the arc off of the contacts and into the arc chamber. The arc chamber features arc splitter retainers with integrated pressurizing walls, which facilitates heat transfer from the arc providing additional cooling and quick transition into the magnetically induced splitter plates. In turn, the twelve (12) splitter plates attract, segment and cool the arc for full extinction.
