      • Features

        1. High-capacity
        2. Max. switching current: 40 A
        3. Detection of main contact welding makes it possible to construct a safety circuit (2a1b)
        4. Compact size
        5. Low operating power: 1,880 mW (holding power: 170 mW)
          The coil holding voltage can be reduced up to 30% V of the rated coil voltage. This equals to operating power of approximately 170 mW, which contributes equipment energy savings.
          * Coil holding voltage is the coil voltage after 100 ms from the applied rated coil voltage.
        6. Contact gap: 3.2 mm (VDE0126 compliant)
          Compliant with European photovoltaic standard VDE0126
          Compliant with EN61810-1 2.5 kV surge withstand voltage (between contacts) 
          Contact gap (initial)
          Form A contactMin. 3.2 mm each contact
          Form B contactMin. 0.7 mm
          Min. 0.5 mm (When Form A contact welded)
        7. Mirror contact mechanisms: Compliant with EN60947-4-1 mirror contact
          Detection of main contact welding makes it possible to construct a safety circuit.
          ・Designed so that Form A contact and Form B contact will not close at the same time.
          ・When Form A contact welded, Form B contact gap of at least 0.5 mm is maintained.
          Note)  Form B contact, when used to monitor the condition of Form A contact, can be used exclusively as an auxiliary contact.
