[Protective construction] Flux-resistant

Please refer to "the latest product specifications" when designing your product.
Please refer to "Cautions For Use" in the catalog, and "Related Information" on our website.

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 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.
