1S30Arc Sensor
1S30A
Single through hole sensor 3m detection range 5 – 6 m spacing
1S30B
Dual sensor 5 – 6 m spacing
1S30Arc Sensor
Mounted in each segregated switchgear chamber
Provides detection in the forward direction through 180º
Also detects reflected arc light - so mounting position not critical
Insensitive to day light or general
artificial lighting

1S23 Application
1S23 is Designed to Interface with an Overcurrent Relay
1S23 Outputs are fed into the Binary inputs of the Overcurrent Relay
An ARC trip may be Current Checked using a fast Overcurrent element in the Overcurrent Relay
The ARC trip may also be implemented without any form of interlocking using the Overcurrent Relay
The Overcurrent Relay is needed to perform the Circuit Breaker Tripping and 1S23 Supervision Alarming
