1. Overview

TCM1 series of moulded case circuit breaker is one of our new type productsdeveloped and manufactured by adopting international advanced technology. It is used for distributing power, protect the lines, power and devices from overload, undervoltage and short circuit in the electricity distribution networks. It features small volume, high short circuit breaking capacity and perfect protection functions, which is the good method of improving power supply reliability.

It conforms with the standards of IEC61009 and GB14048.2-2008.

2. Application

TCM1 series of moulded case circuit breaker is applicable to a line of AC 50Hz/60Hz, rated voltage 400V for low voltage distribution system. and rated current up to 630A. It can protect the line and motor from ground fault. It can also be used for indirect protect people from potentially deadly electrical shock hazards. It is used for distributing power, protect the lines, power and devices from overload, undervoltage and short circuit in the electricity distribution networks. It can also be used for infrequent line conver-sion and infrequent motor start.
