Features

Comprehensive product range

  • Wide choice of relays from DIN rail to panel mount, single-phase and three-phase options, and current ratings from 0.1 A to 125 A to meet your application needs.

Simplified installation and mounting

  • Compact solution with 6 mm width for SSL range reduces space and allows easy mounting on the socket.
  • Premounted version (relay mounted on socket) available in SSL range to ease selection and save installation time.
