Our advantages are lower prices,dynamic sales team,specialized QC,strong factories,high quality products and services for Competitive Price for Moulded Case Circuit Breaker-FTM2 Supply to Ireland, We welcome new and old customers from all walks of life to contact us for future business relationships and mutual success!

Product Features

The FTM2 series of moulded-case circuit-breakers can be equipped with:

- thermomagnetic trip units, for direct and alternating current network protection, using the physical properties of a bimetal and an electromagnet to detect the overloads and short-circuits;

- electronic trip units, for alternating current network protection. Releases with microprocessor technology obtain protection functions that make the operations extremely reliable and accurate. The power required for operating them correctly is supplied straight from the current sensors of the releases. This ensures that they trip even in single-phase conditions and on a levelwith the minimum setting.

- Small size,compact design

- With the same frame size, the circuit breakers are available wi th different breaking capacities and different rated currents.

- Widely adjustable electronic trip units

- Frames made of rigid materials of recyclable enginnering plastics,

- Modular and easy-to-fit internal accessories

- The internal accessories are extremely easy to install. No tools are required because they are simply snapped into place in the accessories compartments to the left and right of the handle.

 Telecommunication trip unit

The main protection function: long time-delay overload protection, short time-delay short circuit protection, instantaneous short circuit protection, residual current protection, ground-fault protection.

telecommunication interface:

- The trip unit allows the circuit breaker to be integrated in a communication network based on the Modbus protocal,the devices provide standard RS485 interface as the physical means for tada transmission. It allows a wide range of information to acquired and transmitted remotely.

- programming the electronic trip unit in remote mode;

- to know the state of the circuit breaker(open/closed/tripped) in remote mode.
