For Current Transformers: Class 0.5s is more accurate when you got low values of current. For class 0.5s and with a current between 1-5% In, you got on class 0.5s a 0.75% error. For class 0.5 and...

These utilization categories determine what load the contactors are switching: AC-7a are for slightly inductive loads for household appliances for example mixers and blenders AC-7b are for motor...

Torque settings for NSX MCCB power terminals are below: 100amp and less rated frames = 10Nm 125-250amp rated frames = 15Nm 400-630amp rated frames = 50Nm These are for the top and bottom power...

The maximum earth loop Impedance figures can be found on the attached pdf files. 16A to 250A The standard MCCB's used for ratings of 16A to 250A with part numbers beginning with...

The GV range of motor protection circuit breakers (MPCB) can be used on a single-phase network by connecting 2 of the poles in series. In this way, all 3 motor protection circuit breaker poles are...

Internal Arc Classification IAC A-F, A-FL and A-FLR are defined in IEC 62217-200 and help to define internal arc performance of medium voltage or high voltage switchgear. The following definitions...

EcoStruxure Facility Expert TM evolution Schneider Electric is improving and enhancing your experience by transitioning from EcoStruxure Facility Expert to a new solution ecosystem. Here a...

Most industrial proximity sensors (inductive, capacitive, ultrasonic and photo electric) are solid state. The term solid state refers to the type of components used within the sensor. Solid state...

In order to identify in our code which M172 model we are using we need to use the two (2) internal variables located in "Operators and blocks". The variables are Par_POLI (Polycarbonate...

There is often confusion between the in-phase and the In-sync features of ASCO transfer switches. It is important to understand the difference between these features especially during the process of...

The software to program the Modicon M171O (optimized) is EcoStruxure Machine Expert HVAC. The software can be downloaded from our website:...

PNP and NPN type outputs are available as 3-wire sensors with a DC voltage power supply (the voltage limits are dependent on the specific sensor): PNP type: switching on the positive voltage load NPN...

For many years, mainland Western Europe has used a mains 3 phase electricity supply nominally rated at 380V AC 50Hz while the UK used 415V AC 50Hz. Currently, all Western European 3 phase supplies...

For many years, mainland Western Europe has used a mains electricity supply rated at nominally 220VAC 50Hz while the UK used 240VAC 50Hz. In 1994, the European Union state members decided to proceed...

In the majority of cases, the overload of a star delta starter is fitted below the delta contactor with wiring connections to one side of each of the motor windings. The other side of the windings...
