For high industrial loads

If currents above 10 A have to be switched, standard relays are subject to high wear and quickly reach the limits of their service life. Our power switches has been specially developed to control high AC loads. They are ideally suited for motors or heating elements up to 75 A and can be used in many other power applications.

Our product range

Power-solid-state relays (PSSR)

Our solid-state contactors are far superior to mechanical contactors. They achieve higher switching speeds and are more robust and durable. They switch ohmic and inductive loads silently, wear-free and reliably – even in dusty or chemically aggressive atmospheres. Our solid-state contactors are available for 1- and 3-phase mains.

Power-solid-state relays (PSSR)
Your benefits
  • Switching currents of up to 75 A
  • High shock and vibration resistance
  • Variants for mounting on DIN rail TS35
  • Variants for direct mounting on a metal surface
  • Output connections ring lug suitable


Conventional contactors are oversized for some power applications in which industrial relays wear quickly and only achieve a short service life. This is where our PWR miniature contactors are used. Thanks to switching currents of up to 30 A, a double-break contact and a significantly larger contact gap, they are able to switch industrial loads reliably.

Your benefits
  • 1 NO contact (30 A) and 2 NO contacts (25 A)
  • AgSnO Contact material
  • Double contact to increase contact opening
  • Direct mounting on DIN rail TS35
  • Built-in status indicator
