Phoenix Contact CBM electronic device circuit breakers

Phoenix Contact has released highly compact, all-in-one, multichannel CBM electronic device circuit breakers, designed to help save on panel space.

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. The multichannel circuit breakers combine up to eight channels within the one unit to reduce the need for space.

The 41 mm-wide breakers are extra slim for ease of use and the compact design ensures technicians can place the device into smaller cabinets. The unit has a smaller footprint, so there is greater space within the cabinet for other components.

Purpose-built, the circuit breakers protect susceptible electronic equipment against voltage dips, overloads and short circuit currents, and help deliver maximum system availability.

The devices feature a remote reset to clear a tripped channel, which eliminates the need to physically open a cabinet to reset a circuit. The channel can be cleared from a programmable logic controller or at the operator interface. The breaker comes with sophisticated remote status signalling concepts, which enable easy monitoring from any location.

The devices feature an adjustable current per channel of 0.5 to 10 A, allowing technicians to choose from six ranges and to set the required protection level for individual circuits. This eliminates the need for individual circuit breakers to be placed in the cabinet. An electronic locking mechanism prevents accidental changes to the set nominal currents.

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

The devices are available in 4- and 8-channel configurations to protect loads at 24 VDC against overload or short circuit currents. They feature push-in technology for fast, tool-free connection and wiring.
