HE-S Relays | Power Relays ( Over 2A )

Protective construction: Flux-resistant

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 contact	Min. 3.2 mm each contact
   Form B contact	Min. 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.
