The switching contact of this Siemens load feeder is electromechanical, providing reliable operation for direct starting applications.
The motor protection for this load feeder is of the bimetal type, which offers adjustable response current for current-dependent overload release.
The operating voltage at AC-3 is rated at a maximum of 400V, and the operating current at AC-3 at 400V is rated at 15.5A.
The main circuit of the 3RA1120-4BD26-0AP0 has 3 poles for the main current circuit, and it is designed to handle a service power at AC-3 at 400V with a rated value of 7.5kW.
This device requires an AC control supply voltage, with a rated frequency of 50Hz and a rated value of 230V at 50Hz for AC.
Yes, the product extension includes auxiliary switches, although it does not specify the number of NC, NO, or changeover contacts for auxiliary contacts.
The breaking capacity limit for short-circuit current (lcu) at 400V is rated at 50kA.
The load feeder is designed for snapping onto 60 mm busbar systems and can be mounted in various positions, including vertical with a rotation of +/-90° and tilting of +/-22.5°.
The dimensions are 45mm in width, 183mm in height, and 148mm in depth, with a center line spacing of 60mm. There are specific distances to be maintained from earthed parts and conductive elements for safe installation.
The electrical connection for the main current circuit is a screw-type terminal, compatible with various conductor cross-sections including solid, stranded, and finely stranded with conductor end processing.
