200 amp Circuit Breaker for Comm. Shelf

Manufacturer Part Number: CMDR-200

The Newmar CMDR-200 is a high-current circuit breaker designed for use in compatible communications power shelves and DC power distribution systems. It provides circuit protection for telecommunications equipment by interrupting current during an overload or fault condition. Intended for specialized communications infrastructure, it supports maintenance and protection of power distribution equipment used in network cabinets, radio installations, and telecom equipment rooms. The manufacturer and supplier identify the part as a 200 A circuit breaker for a communications shelf.

The CMDR-200 is intended for integration with a compatible communications shelf rather than general-purpose household distribution equipment. Its high current rating makes correct shelf compatibility, cable sizing, operating voltage, and fault-current protection especially important. The exact voltage rating, breaker pole configuration, trip mechanism, and interrupting capacity could not be independently verified from the available listing, so these should be confirmed using the equipment label or manufacturer documentation before installation.
