Description

The ST-520 capacitor trip unit is part of Square D's Class 9810 product line, engineered to supply the necessary energy to trip circuit breakers during power outages or insufficient control power scenarios. This unit charges a capacitor to store energy, which is then released to operate the trip mechanism of a circuit breaker when needed. The ST-520 is particularly useful in systems where maintaining the ability to trip breakers during power failures is essential for safety and equipment protection.

Features:

  • Provides stored energy to trip circuit breakers during power loss
  • Ensures safe operation of electrical systems in critical conditions
  • Compact design for easy integration into existing setups
  • Reliable performance in various industrial applications
