Products we supply
Circuit breakers, contactors, motor starters, power-factor correction and metering, selected as one coordinated low-voltage protection system.
01Overview
Powersense supplies air, moulded-case and miniature circuit breakers, residual-current devices, contactors, drives and measuring equipment, and engineers their coordination: fault levels, selectivity, power-factor correction and monitoring, so that protection behaves as one system.

02Scope and process
The prospective short-circuit current at each board is taken from the network study (IEC 60909), together with load and diversity data.
Rated current, breaking capacity (Icu and Ics), utilisation category and trip curves are selected to IEC 60947-2 and IEC 60947-4-1.
Discrimination between upstream and downstream devices is verified from manufacturer tables or time-current curves, and back-up protection is applied where it is used.
Residual-current devices and automatic disconnection of supply are verified against fault-loop impedance and disconnection times (IEC 60364-4-41).
Capacitor banks and controllers are sized from measured demand, with detuned reactors or filters where harmonics are present.
Network analysers and communicating devices are specified to report current, power, power factor and harmonics to the SCADA or BMS.
03Standards
These standards form the technical basis for design and equipment selection. The exact set is confirmed for each project against the national regulations in force.

06Technical notes
Icu is the ultimate breaking capacity and Ics is the service breaking capacity, stated as a percentage of Icu. After breaking a fault up to Ics, the breaker remains fit for service. Both are compared with the prospective fault level.
No. A soft starter limits starting current and mechanical shock. Energy savings on pumps and fans come from AC drives that match motor speed to demand.
