Information About S29387
The S29387 is a shunt trip accessory developed for Schneider Electric PowerPacT H-, J-, and L-frame molded case circuit breakers. It is used to provide remote tripping functionality by electrically actuating the breaker when the control voltage exceeds the specified threshold. H- and J-frame breakers may use either thermal-magnetic or Micrologic electronic trip units, while L-frame breakers are equipped exclusively with Micrologic trip units, ensuring compatibility across multiple configurations. This accessory is commonly applied in safety systems, emergency shutdown circuits, and automated control schemes requiring reliable remote breaker operation.
Key Features
- PowerPacT Compatibility: Designed specifically for use with Schneider Electric PowerPacT H-, J-, and L-frame circuit breakers.
- MX Shunt Trip Functionality: Electrically trips the breaker when control voltage reaches at least 70% of its rated value.
- 208–277 VAC Operation: Supports common control voltages used in commercial and industrial power systems.
- Impulse and Maintained Signal Support: Accepts momentary signals of 20 ms or longer as well as continuous control inputs.
- Ground-Fault System Integration: AC shunt trip can be used in ground-fault protection systems when paired with a Class I sensing element.
- Secure Terminal Connections: Designed for AWG 18–14 conductors with defined tightening torque for reliable wiring.
- Certified Accessory: CSA certified to support compliant installations in regulated electrical environments.
The S29387 delivers the reliability and precision required for remote tripping and safety control of PowerPacT circuit breakers in commercial and industrial electrical systems.
