Phoenix Contact CBM electronic device circuit breakers

Phoenix Contact has released compact, all-in-one, multichannel CBM electronic device circuit breakers. With a choice of either a 4- or 8-channel CBM electronic device circuit breaker, users no longer need to stack single 18 mm-wide circuit breakers together in a control cabinet. At 41 mm wide, the compact design ensures technicians can place the device into smaller cabinets, leaving more space within the cabinet for technicians to add other components.

The electronic circuit breakers protect susceptible 24 VDC electronic equipment against voltage dips, overloads and short circuit currents. They feature remote status signalling and a remote reset to clear a tripped channel, eliminating the need for a technician to have to be present to reset a circuit — the channel can be cleared from the convenience of a programmable logic controller or at the operator interface.

The circuit breakers also feature an adjustable current per channel of 0.5 to 10 A. This allows technicians to choose from six ranges and to set the required protection level for individual circuits. An electronic locking mechanism prevents accidental changes to the set nominal currents and push-in technology enables fast and easy connection.

Each unit also comes with an in-built alarm that delivers an early warning when a channel exceeds 80% of the set nominal current. A multistage status indicator that is available for each channel provides constant information about the status of the connected loads.
