Product Description
A power relay with a high capacity and high dielectric strength that can handle momentary voltage drops.
[Features]
·Wiring work is quicker than conventional screw terminals with the new push-in plus terminal block sockets now available in the product series (Wiring labor-hours are approx. 60% shorter than traditional screw tightening terminals.).
·Relay with forcibly guided contacts (EN/IEC 61810-3 VDE certified).
·Supports the CE marking of machinery (Machine Directive).
·Helps avoid hazardous machine status when used as part of an interlocking circuit.
·Available in 4-position and 6-position.
·Terminal arrangement simplifies PWB pattern design.
· Reinforced insulation between inputs and outputs. Reinforced insulation between some poles of different polarity.
[Applications]
·Helps avoid hazardous machine status when used as part of an interlocking circuit.
