Record Plus PremEon* S Electronic trip unit for frames FE and FG

PremEon is a new line of electronic trip units designed to offer uncompromising reliability in all network environments.

The first of the line, PremEon S, combines sophisticated 32 bit technology with a complete set of protection functions. Simple dials provide access to a wide setting range of 0.3 to 1 times In.

Designed to fit the Record Plus line of moulded case circuit breakers, the devices are available as 3 or 4 pole units in a current range of 7 to 630A.

PremEon together with the unique selective and current limiting line of Record Plus line circuit breakers offer strongly improved selectivity between upstream and downstream devices.

The use of highly accurate sensing technology and of state-of-theart electronics, reduces the tolerances on expected tripping currents and the associated time spans to a minimum.

The result as depicted in the time current curve: selectivity up to 10,000A between a upstream breaker set at 180A and a downstream breaker set at 145A.

PremEon makes selectivity possible between downstream and upstream devices with a ratio between settings of 1.25. Selectivity on higher currents is assured by the unique selective and current limiting properties of the implemented Record Plus FG630 (set at 180A) and FE160 (set at 145A) circuit breakers.

Integrated test kit

Simply connect a standard mobile phone charger to the micro USB port and the "TEST" button goes live. Depress it and it checks the full electronic circuit and then trips the connected breaker.
