The Tesla DCO2P25 is a 2 Pole 25A DIN Rail Mounted Changeover Switch, designed for safe and reliable manual switching between two power sources. Engineered for compact switchboard integration, it is ideal for residential, commercial, and light industrial applications where changeover functionality is required.

Key Features:

  • Centre-Off Switching Function: Manual 2-position + centre off changeover operation for isolating and switching between alternate power sources (e.g. grid and generator).
  • 25A Rated Current Capacity: Suitable for AC21 and AC22A category applications—handling resistive and slightly inductive loads.
  • Compact DIN Rail Mount Design: Occupies only 2 modules (35mm) in width, making it ideal for modern distribution boards.
  • Dual Power Compatibility: Rated for 230V AC operation at 50/60Hz, making it compatible with standard single-phase systems.
  • Durable & Safe: Built to IEC 60947-3 standards with 10,000 mechanical operations and a short-circuit current rating of 1200A.
  • High Build Quality: Designed to operate safely within a wide temperature range (-5°C to +50°C), with a tough and reliable contact mechanism.
