Accessories and Spare Parts
For 3RT, 3RH Contactors and Contactor Relays
Accessories for 3RT, 3RH contactors and
contactor relays
Additional load module
• Size S00 for plugging onto the front of the contactors with and
without auxiliary switch block
Coupling links for mounting on contactors of sizes
S0 to S3
DC operation
IEC 60947 and EN 60947
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.
System-compatible operation with 24 DC V, operating range
17 V to 30 V.
Low power consumption in conformity with the technical
specifications of the solid-state systems. A light-emitting diode
indicates the circuit state.
Surge suppression
The 3RH19 24-1GP11 coupling link has an integrated surge
suppressor (varistor) for the contactor coil being switched.
Mounting
The 3RH19 24-1GP11 coupling link is mounted directly on the
contactor coil.
Solder pin adapters
The solder pin adapters for the size S00 contactors are available
in two versions:
• Solder pin adapter for contactors with one integrated auxiliary
contact
• Solder pin adapter for contactors with mounted 4-pole
auxiliary switch block
Screw adapters
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.
Optionally the adapters can be rotated through 90° before
mounting.
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.
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.
