S&C SM-4, SM-5 Power Fuses for Outdoor Distribution Equipment Protection Power fuses are like overdraft protection on checking accounts, and in this case, outdoor power equipment is the bank. Power overloads are like bouncing a check, and fuses respond to overdraws accordingly, protecting the system and keeping it balanced […]

Fusing for Instrument Transformer Circuit Protection

Voltage Transformer or Potential Transformer

If you read our post on “Medium Voltage Fuses for Power Distribution Transformers, you know that power transformers don’t generate electrical power. They transform and transfer power safely between circuits. Current Limiting Fuses for Instrument Transformers Instrument Transformer Fuses are current-limiting fuses with high interrupting ratings used […]

Dual-Element Time-Delay Fuses

Dual-Element Time-Delay Fuses

Dual Element Time-Delay Fuses are designed for AC power distribution system mains,branch and feeder circuits with inductive loads (transformers, motors) or non-inductive loads (heating, lighting) where the short-circuit current is not beyond 200,000 RMS symmetrical amps. Dual-Element Time-Delay Fuses are among the most frequently used fuses in industry because of their economy, particularly in […]
