Features
- Our products are equipped with a various series of types with LED operating
display lamps, built-in diodes (DC surge suppressors), built-in C-R circuit
(AC surge suppressors)
- Our products coils are AC4 rated (AC100/110, 110/120, 200/220, 220/240)
and DC2 rated(DC100/110).
- Our products with four poles are equipped with Arc Barrier.
- Our products can endure the voltage of AC 2,000V (for a minute).
- Our products contacts are gold plated to increase even small amount of load
and contact reliability.
