If the motor's rated current is 300A or less, you can use the TSB300AT.

If the motor's rated current is 300A or more, a current transformer that matches the rated current is required.

The TSB400AT for 400A or less and the TSB500AT for 500A or less are available upon request.

Although the connection method differs from that of a three-phase motor, it can be used as long as the current value is within the current setting range.

Please select from the ED series or SB series.

Please select the TSB400AT product for which you have received a quote.

Only the ED series is compatible with inverter motors. (Frequency range: 20Hz to 200Hz)

In addition, the SB series and 150 series can be used within the range of 30Hz to 60Hz.

Pole change motors cannot be used because the current value changes between 4 poles and 8 poles, for example.

It is not compatible with any Shock Relay.

If the current changes with the heater, you can use Shock Relay. Select the maximum current.

This is not possible.

It cannot be used with the current transformers (CT) provided by our company.

However, if a commercially available high voltage CT is used, it can be used in combination with TSB152.

We recommend purchasing directly from the current transformer manufacturer.

Please select based on the rated current value.

When the ED series is set to "self-hold," the current value for one time remains. After resetting, the current value disappears.

If the operating power supply is turned on while current is flowing through the current transformer, it may malfunction, so be sure to turn on the operating power supply before starting the motor.

The case, base, and transformer must be replaced to panel specifications, and we do not recommend that you replace them yourself.

Please contact a trading company with which you do business and we can reassemble it for you.

Shock Relay 150 series does not support switching between "self-hold" and "Auto reset."

The higher of the two phases is displayed.

The monitor lamp does not light up. Please check the operation by pressing the test button.

Internal components (transformers, power circuit components, etc.) may become damaged due to heat generation.

The current transformer can be connected to any of the U, V, or W phases.

It is also required for the ED series. It is also required for all Shock Relay series.

Changing the DIP switch will not damage the device, but it will not function properly if used as is.

It doesn't matter if you have already switched it over, but be sure to turn off the power once.

The SB series and ED series are CE marked products and comply with IEC standards.

When using Shock Relay for impact stopping, there is a delay in the shock time plus a time delay in the motor contactor, and even if it is possible to stop the motor, there is a risk of damage to the device due to the instantaneous mechanical shock, so it is considered difficult to use.

It doesn't matter whether you connect it to the primary or secondary side.

This varies depending on the conditions, so please make your own judgment based on actual driving.

Instruction Manuals specifies the motor side and the power supply side, but in reality it doesn't matter which side you wire it from.

We do not issue material certificates.

This means that the motor is operating on a starting (locked) current, and there may be an excessive load that prevents the motor from starting.
