Ratchet Relay G4Q
Caution
Product Description
[Features]
· Alternate switching operation due to unique ratchet structure.
· With each pulse, alternate switching to each contact of the 2 poles is carried out.
· Optimal for alternate operation, switching operation of motors, etc.
· Contact switching carried out due to unique ratchet structure.
· Clears voltage resistance AC2, 000V.
