Phoenix Contact SCB Compact string combiner boxes

Phoenix Contact has launched the SCB Compact string combiner boxes with inline fuses that are even smaller, more flexible and powerful than its predecessors.

String protection is achieved outside the control cabinet, which reduces the thermal stress inside the connection box, since it allows the fuses mounted on the outside to release their waste heat into the environment. The inline fuse and all other components in the string combiner box, such as the circuit breaker, surge protection and monitoring system, are exposed to lower operating temperatures. Over the long term, this means better performance and longer service life for the entire system and also allows operation at higher ambient temperatures.

Moving the fuses to the outside makes the design of the connection boxes significantly smaller. The lower volume reduces transportation and storage costs, while the product’s light weight means that a single person can install it.
