NIKKO ELECTRIC MFG. CO., LTD. To manufacturer site ▶

As a specialist of breaker products, we have delivered a lot of products for railroad vehicles, signals, and broadcasting equipment. Characteristically, for the overload current sensing devices, fully magnetic breakers with a number of advantages are used. For example, working current on them are not affected by ambient temperature. We also manufacture customized products which utilize those advantages of the fully magnetic breakers.

 
PICK UP & NEW ITEM



Direct current high-voltage switch for solar energy generation Supporting
DC300V/10A
Breaker for wiring with leakage alarm function and neutral line open-phase protection Breaker for wiring with direct current leakage alarm

*For switch of joint box for solar energy generation

  • ・The switch can open and close DC300V-10A in 2-pole series connection.
  • ・Suitable for switches used for joint boxes for solar energy generation

*Supporting print-circuit boards

  • ・In addition to tab terminals, printed board terminals are available.

*Supporting the JWDS-0029 standard

  • ・The standard of Japan Electrical Wiring Devices and Equipment Industries Association, JWDS-0029, is supported.

These breakers for wiring have the leakage alarm function and the neutral line open-phase protection function.
In addition to the overload protection and short-circuit protection functions as a circuit breaker, the leakage alarm function and the neutral line open-phase protection function are integrated into one breaker. Accordingly, a body can be small and light.

Install a unit on nongrounding direct current of a control source of the power generating or substation facility, and the unit detects earth current and sends alarms when earth current is generated due to deteriorated insulation of the direct current circuit.
In addition to the overload protection and short-circuit protection functions as a circuit breaker, the direct current earth alarm function is integrated into one breaker. Accordingly, the body can be small and light.

This way makes the size of the board smaller than the separated setting of a breaker, leakage relay, and CT.
When this unit is used for a circuit with a number of branches, the cost can be lower compared to the case where a multi-channel earth detection relay is used.
