Soft starter 250 kW, 400 V, with bypass

Soft starter 250 kW, 400 V, with bypass. A soft starter ramps the voltage at start-up, lowering starting current and mechanical shock for fixed-speed loads such as conveyors, crushers, compressors and pumps.

Key features

• Power: 250 kW
• Bypass: built-in
• Comms: Modbus option
• Adjustable start and stop ramps, current limit and motor protection

When to choose a soft starter instead of a drive

• The load always runs at full speed: a soft starter is cheaper and more efficient at full load.
• If the load varies (fans, pumps), a variable speed drive saves far more energy.

Connecting to Plantmargin

Use the Modbus option, or wire run and fault contacts to a digital input module. Plantmargin reads starts, current and faults every 10 seconds through the edge gateway, stores it for years as hourly figures, draws it against its normal band, and uses it in cost per unit, alarms and verified savings. The installer pack for your plant lists the exact register or channel to use.

Installation

• Size for the motor current and the number of starts per hour; heavy starts (crushers, mills) need a larger unit.

Warranty and support

• Manufacturer's warranty, usually 12–24 months from delivery; the exact period is stated on your quotation.
• Supplied with the datasheet and manual; calibration or test certificate where the product has one.
• Installation, commissioning and connection to Plantmargin can be quoted with the product.
