FEATURES
1. High-capacity and long life 35A 277V AC 5×10

(long life
type)
2. Electrical life (resistive load)
3. Compact size and low operating power
W: 30 × L: 36 × H: 40 mm W: 1.181 × L: 1.417 × H: 1.575 inch
Operating power: 1,880 mW (holding power: 170 mW)
4. Reduced coil holding voltage contributes to saving
energy of equipment
The coil holding voltage can be reduced up to 30%V of the
nominal 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 nominal coil
voltage.
5. Contact gap: 3.2 mm .126 inch (VDE0126 compliant)
Compliant with European photovoltaic standard VDE0126
Compliant with EN61810-1 2.5 kV surge breakdown voltage
(between contacts)
6. Insulation distance (initial)
• Between Form A contact and coil: Min. 11.0 mm .433 inch
(Clearance/Creepage)
• Between Form B contact and coil: Min. 3.2 mm .126 inch
(Clearance/Creepage)
• Between contact sets: Min. 8.2 mm .323 inch (Clearance/
Creepage)
7. Contact gap (initial)
• Form A contact: Min. 3.2 mm .126 inch/each 1a contact
• Form B contact: Min. 0.7 mm .028 inch
Min. 0.5 mm .020 inch (When Form A contact
welded)

Detection of 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.
• Designed so that a contact interval of at least 0.5 mm .020
inch is maintained.
* Form B contact, when used to monitor the condition of Form A contact, can be
used exclusively as an auxiliary contact.
