What type of component is this?
This is a Siemens SIRIUS power contactor used for switching electrical loads in industrial control circuits. It is a 3-pole contactor with an integrated normally open auxiliary contact.
What is the rated motor power at 400 V AC-3?
The contactor is rated for 3 kW at 400 V under AC-3 utilisation, making it suitable for small motor switching applications.
What coil voltage does this contactor use?
It uses a 24 V DC control coil. For the standard 3RT1015-2HB41 version, the coil operating range is listed as 0.85 to 1.1 times the rated control supply voltage.
How many main contacts are fitted?
The contactor has three normally open main contacts for the main current circuit and no normally closed main contacts.
Does it include an auxiliary contact?
Yes. It includes one instantaneous normally open auxiliary contact and no instantaneous normally closed auxiliary contacts.
What connection type is used?
The contactor uses Cage Clamp spring terminals for the main current circuit, auxiliary circuit and control circuit connections.
What size is the contactor?
It is a Siemens SIRIUS size S00 contactor, with compact dimensions of approximately 45 mm wide, 60 mm high and 73 mm deep.
Can it be mounted on a DIN rail?
Yes. It can be screw mounted or snapped onto a 35 mm standard mounting rail in accordance with DIN EN 50022.
What is the rated operational current at AC-3?
At 400 V AC-3, the rated operational current is 7 A.
What is the AC-1 current rating?
At 400 V AC-1, the rated current is 18 A at 40 °C ambient temperature. At 60 °C ambient temperature, the rating is 16 A.
What ambient temperature range is it designed for?
The operating ambient temperature range is -25 °C to +60 °C.
What is the IP rating?
The front of the contactor is rated IP20, and the terminal area is also listed as IP20.
What conductor sizes can be connected?
For main and auxiliary contacts, the terminals accept solid conductors from 0.25 to 2.5 mm², finely stranded conductors with end processing from 0.25 to 1.5 mm², and AWG conductors from 24 to 14.
What fuse ratings are specified for short-circuit protection?
