Design and Performance
Reliable Control Signal Switching for Control Circuits
As an auxiliary contactor, the 3RH2131-1BB40 switches control signals in the control circuit with standard-compliant terminal designations and reliable, time-saving connection technology.
Multiplied Outputs for Simultaneous Auxiliary Circuit Switching
Thanks to the multiplication of outputs, simultaneous switching of several auxiliary circuits is possible, simplifying control panel design for applications requiring multiple coordinated control signals.
Positively Driven Contacts for Safety Applications
All contacts are available with positively driven operation for safety applications, as well as SUVA versions, supporting compliance with functional safety requirements in machine control circuits.
Exceptional Mechanical Durability
Rated for a typical 30,000,000 mechanical operating cycles, this contactor relay supports long-term reliability in control circuits with frequent switching, minimizing the need for premature replacement.
Climate-Resistant, Globally Approved Design
Climate-resistant with high contact reliability, this relay is suitable for use worldwide thanks to corresponding approvals (including IEC and UL/CSA), and is available with AC or DC operation and screw or spring-loaded terminals.
