INSTALLATION CONTACTOR, 40A 4N0; Operating Voltage: 400V AC; Switching Power AC1: 8.8kW; Switching Power AC3: 3.7kW; ...
The is an Installation Contactor with 4NO contact configuration. ESB series relay for loads to be automatically controlled through high number of operations. They are part of a complete range of DIN rail products and can be integrated easily in dedicated panels. The ESB contactor is fitted with a DC solenoid actuator and therefore hum-free. The noise during switching is barely audible making it beneficial. An incorporated varistor protects the coil against remote lightning strikes and over volts up to 5kV. In addition, limiting of the interference voltage peaks of the solenoid system. The contactor can therefore be combined with programmable logic controllers. There is no need for a protective circuit. The solenoid system is provided with radio interference suppression.
