Square D S29382 Circuit Breaker Shunt Trip 12V Dc

Product Description

The SQUARE D S29382 is a shunt trip accessory designed for use with molded-case circuit breakers requiring remote trip capability. The shunt trip coil operates at 12 volts DC control voltage, allowing the breaker to be opened electrically from a remote location when a signal is sent to the coil. This type of accessory is commonly used in fire alarm systems, emergency shutoff circuits, and building automation panels where a controlled, remote-initiated trip is required. Licensed electricians install this component during panel construction or retrofit work.

The S29382 is suited for commercial and industrial electrical installations where H Frame, J Frame, or L Frame molded-case circuit breakers are deployed. Typical applications include emergency power-off systems, fire suppression tie-ins, and any control scheme that requires automatic breaker tripping based on an external low-voltage signal. The 12-volt DC operating voltage makes it compatible with standard control circuits commonly found in these installations.

Key Features

• Shunt trip coil operates at 12 volts DC control voltage
• Compatible with H Frame, J Frame, and L Frame circuit breakers
• Enables remote electrical tripping of the breaker from a control circuit
• Compact form factor for integration into existing breaker frames
• Sold as a single-unit accessory (package quantity of 1)

Compatibility

Designed for use with H Frame, J Frame, and L Frame SQUARE D molded-case circuit breakers that accept a shunt trip accessory module.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize the circuit breaker and verify the panel is completely powered down before installing or removing any breaker accessory. The shunt trip coil must be connected to the correct control voltage source as specified for this unit. Do not apply voltage to the coil terminals during mechanical installation.
