ABB WBP Voltage Transformer Fuses - IEC Standard 7.2kV-36kV

ABB MV HV Medium - High Voltage Fuses

Indoor Fuses for MV Medium Voltage Cable Networks

ABB WBP Voltage Transformer Fuses - IEC Standard 7.2kV-36kV

 

ABB WBP instrument transformer fuse-links are used to protect medium voltage (MV) switchgear equipment against short-circuits into indoor voltage transformers. Protection of ABB medium voltage switchgear equipment is very effective due to unlimited breaking capacity and short circuit current limitation. Compact ABB fuse dimensions ensure ABB WBP fuse compatability with various types of MV-HV switchgear up to 33kV/36kV, including flame-proof types.

ABB WBP IEC Indoor Voltage Transformer Fuse Features

• Unlimited breaking capacity
• Short-circuit currrent limiting
• Small dimensions

 

ABB WBP Voltage Transformer Fuse Ratings - IEC 7.2kV-36kV

• Rated fuse voltage 7.2kV - 36kV
• Rated fuse current 0.4Amps - 0.8Amps
