The leading circuit breakerError prevention earth leakage circuit breaker (32GS-i) of green-orienter Kumsung!
Kumsung 32AGS-25 and 32GS-I earth leakage circuit breaker series
- 32AGS-25 (Auto recovery)
- It is an intelligent auto recovery earth leakage circuit breaker to detect a problem and its cause by monitoring the actual leakage on the load side using a detecting circuit instead of being supplied with power from a battery. The auto recovery is time-fixed type.
- - KC certification
- - Bidirectional communication (notification)
- - Circuit breaking and then line monitoring in an event of leakage
- - Auto recovery when the leakage is solved
- 32GS-I (Error prevention)
- It is an IGR earth leakage circuit breaker having a resistance to capacity leakage by resolving the malfunction of existing ones. By solving the trip due to the capacity leakage current between the wiring and the ground, it has been improved to have individual breaking values for capacity and resistance leakage, respectively.
- - IGR (resistance leakage), 24 mA
- - IGC (capacity leakage), 70 mA
- - Same working speed as normal circuit breakers
- - Improved resistance to power noise
