The Siemens Contactor Relay is an auxiliary contactor designed for controlling, switching, and signalling circuits within industrial applications. It features 4 normally open (NO) contacts and operates with a DC control supply voltage.
Yes, the Siemens Contactor Relay is designed for screw and snap-on mounting onto a 35 mm standard mounting rail according to DIN EN 50022, which makes it suitable for DIN rail installations.
The front side of the contactor relay is rated at IP20, providing protection against solid objects larger than 12.5 mm but not against water.
The ambient operating temperature range for the contactor relay is between -25°C and +55°C, making it suitable for a variety of industrial environments.
The control supply voltage required for the contactor relay is 24 V DC, which is the rated value for its operation.
The contactor relay has dimensions of 48 mm in height, 45 mm in width, and 68 mm in depth.
The contactor relay uses screw-type terminals for its electrical connections, providing a secure and reliable connection for auxiliary and control current circuits.
The B10 value for the contactor relay is 400,000 at 0.3 times the rated operational current (Ie), which indicates the number of operations before 10% of components typically fail under a high demand rate.
The T1 value for the proof test interval or service life according to IEC 61508 is 20 years, indicating the designed duration for reliable operation before a proof test or replacement is recommended.
The contactor relay is designed with finger-safe terminals to provide protection against direct contact with electrical parts, reducing the risk of electrical shock during installation or maintenance.
