Siemens 3RA61 Series Load Feeder, 1.5kW Power, 4A Current - 3RA6120-1CB32


This load feeder is a Compact direct-on-line starter designed for three-phase motor control and protection in industrial settings. It accepts 24 V AC/DC control supply and switches up to 690 V AC in the main circuit while providing adjustable overload protection for currents from 1 A to 4 A. The unit is intended for DIN-rail installation with screw and Snap-on mounting and offers IP20 front protection for use in controlled electrical cupboards.

Features and Benefits:


• Adjustable overload range 1 to 4 A protecting motors from overloads
• 690 V insulation voltage enabling high-voltage switching capability
• 3-pole design providing three-phase motor control and isolation
• Low holding power 2.8 W AC reducing control-circuit energy draw
• Mechanical endurance 10 000 000 cycles ensuring long operational life

Applications


• Suitable for starting small three-phase motors up to 1.5 kW
• Used with industrial control panels requiring IP20 protection
• Ideal for OEM assemblies needing Snap-on screw mounting
• Can be used in installations demanding CSA, UL and EAC approvals
• Used for straightforward DOL motor starting and Basic motor protection

What control voltages can the unit accept?


It operates from 24 V AC or 24 V DC for the control circuit (50/60 Hz).

How is short-circuit protection implemented for auxiliary circuits?


Auxiliary and signalling circuits require gL/gG fuses of specified ratings such as 10 A or 4 to 6 A depending on the circuit.

What are the endurance expectations for electrical contacts?


Auxiliary contact electrical endurance reaches up to 200 000 switching cycles at AC-15, 6 A, 230 V.
