Accessories for 3RT, 3RH contactors and
contactor relays
Additional load module
Solder pin adapters
• Size S00 for plugging onto the front of the contactors with and
without auxiliary switch block
The solder pin adapters for the size S00 contactors are available
in two versions:
• Solder pin adapter for contactors with one integrated auxiliary
contact
Coupling links for mounting on contactors of sizes
S0 to S3
• Solder pin adapter for contactors with mounted 4-pole
auxiliary switch block
DC operation
IEC 60947 and EN 60947
Screw adapters
The coupling link is suitable for use in any climate. It is finger-
safe according to EN 50274. The terminal designations comply
with EN 50005.
Plug-on adapters improve the accessibility of the screw fixing for
size S0 contactors. As a result it is possible to position the
screwdriver vertically even when using insulated screwdrivers or
power screwdrivers.
System-compatible operation with 24 DC V, operating range
17 V to 30 V.
Optionally the adapters can be rotated through 90° before
mounting.
Low power consumption in conformity with the technical
specifications of the solid-state systems. A light-emitting diode
indicates the circuit state.
Sealable covers for sizes S00 to S12
When contactors and contactor relays are used in safety-
oriented applications, it must be ensured that it is impossible to
operate the contactors manually.
Surge suppression
The 3RH19 24-1GP11 coupling link has an integrated surge
suppressor (varistor) for the contactor coil being switched.
For SIRIUS contactors there are sealable covers available for
this purpose as accessories; these prevent accidental manual
operation. These are transparent molded-plastic caps with a
bracket that enables the contactor to be sealed.
Mounting
The 3RH19 24-1GP11 coupling link is mounted directly on the
contactor coil.
