S100 type, S200 type, S100PJ type

This protective device (lightning arrester) combines a high performance 3-electrode ceramic arrester combined with a high quality ZNR varistor and, though compact in size, is very sturdy and provides excellent surge protection and current withstand capacity.

 

S111 type, S112 type, S1112 type

These devices are used as lightning protection for railroad signal level crossing control systems (HO type) open track circuits. The device is a single, compact protective device (arrester) that has the same performance as the S100 protective devices (for signals) that conventionally exist separately on the DC 26V power supply, on the track and on the relay output.

 

S24 type

This protective device (arrester) protects equipment from irregular voltage, such as lightning surges that may enter signal equipment power supply circuits and signal circuits.

 RoHS approved
These are highly reliable, high performance lightning arrester tubes that are used in a variety of protective devices for railroad standard signals, communications and power transforming, and protect people, weak electrical current equipment and signal cables, communication cables and control cables from the ground potential rise that may occur in the event of a substation accident, etc., as well as from irregular current from lightning surges that may have been induced along cables, etc.

 

 SU10L[ ]type, SU10H[ ]type

This product is a protective device that protects equipment from irregular voltage and current that may be applied to communication transmission circuitry and the like from lightning surges, etc.

 

[ ]model

This protective device (arrester) is used to protect insulators on AC train lines in the event of insulator flashover, and to prevent ground potential rise in platforms as well as electropotential rise in substation earthing systems in the event of a bus ground fault at an AC substation.

 
 
 

Relay coil

   
Relay coil    

SU type, SUR type

This device is a relay coil fitted with a protective device that protects people and equipment from irregular current that may be induced onto railroad tracks when a relay coil has been installed between communication equipment and track and track and communication equipment, in order to match impedance and lessen induction voltage.
