Ratchet Relay G4Q

Caution
Product Description
An alternating operation type ratchet relay with a unique ratchet mechanism.
[Features]
· Each 2-pole contact performs alternating operation switching with each pulse.
· Uses a unique ratchet mechanism for contact switching.
· Features a dielectric strength of 2, 000 V AC.
[Applications]
· Ideal for alternating operations or transfer/switching operations on motors etc.
