This Siemens contactor relay is an auxiliary contactor designed for various control applications. It features 4 normally open (NO) and 4 normally closed (NC) contacts, suitable for switching and controlling circuits.
Yes, the contactor relay is designed for screw and snap-on mounting onto a 35 mm standard mounting rail according to DIN EN 50022.
The front side of the contactor relay has a protection class of IP20, which means it is protected against solid objects larger than 12.5 mm but not against water.
At AC-15, the operating current ratings for the contactor relay are 10 A at 230 V and 6 A at 400 V.
The ambient operating temperature range for the contactor relay is between -25°C and +55°C.
This contactor relay is equipped with screw-type terminals for making auxiliary and control current circuit connections.
The control supply voltage for this contactor relay at AC is rated at 230 V at 50 Hz and 277 V at 60 Hz.
The B10 value for the contactor relay is 1,000,000 at 0.3 times the rated operational current (Ie), which indicates the number of operating cycles expected before 10% of a batch of contactors could fail.
The T1 value for proof test interval or service life according to IEC 61508 is 20 years for this contactor relay.
To ensure safety when using the contactor relay, it is important to follow the installation guidelines provided by the manufacturer and ensure that the device is used within its specified ratings and environmental conditions.
