Reduced Voltage Starters Solid State ASTAT XB, XBm Soft Starters Accessories

Section 2

Semiconductor Fuses Semiconductor fuses can be used with ASTAT XB and XBm soft starters to reduce the potential for damage to SCRs from transient overload currents and for Type 2 coordination. ASTAT XB and XBm soft starters have been tested to achieve Type 2 coordination with semiconductor fuses. Suitable Bussmann and Ferraz/Mersen semiconductor fuses are detailed below:
