Product Description P/N: STR23SP
Description
The Schneider Electric STR23SP is an advanced electronic trip unit designed to provide precise overcurrent and short-circuit protection within Compact NS circuit breakers. This solid-state module continuously monitors electrical loads and directs the breaker mechanism to safely disconnect power during hazardous fault conditions. By delivering highly accurate fault detection, the unit prevents catastrophic equipment damage and maintains operational continuity in commercial electrical distribution networks.

Information About STR23SP
The STR23SP is a direct-replacement microprocessor-based module engineered exclusively for seamless integration into Schneider Electric and Merlin Gerin Compact NS400 to NS630 series molded case circuit breakers. It features robust solid-state circuitry that remains largely unaffected by ambient temperature fluctuations, offering superior reliability compared to traditional bimetallic thermal-magnetic units. Facility managers and electrical technicians deploy this component to safeguard heavy-duty branch circuits and feeder lines requiring accurate, adjustable protection parameters. The architecture includes accessible dial settings on the front faceplate, allowing operators to fine-tune long-time and short-time tripping thresholds to match specific facility load profiles precisely.
Key Features:
● Solid-State Sensing: Utilizes microprocessor technology to provide highly accurate electrical current monitoring without ambient thermal interference.
● Adjustable Protection Parameters: Features integrated rotary dials for precise calibration of long-time and short-time overcurrent trip thresholds.
● Breaker Compatibility: Engineered specifically to integrate directly into the chassis of Merlin Gerin and Schneider Electric Compact NS400 to NS630 breakers.
● Instantaneous Fault Clearing: Initiates an immediate breaker trip response when extreme short-circuit currents are detected to prevent severe infrastructure damage.
● Front-Facing Diagnostics: Keeps all calibration dials and operational test ports easily accessible for routine electrical maintenance and safety audits.
● High-Dielectric Enclosure: Housed within a rugged polymer casing that shields sensitive internal electronic components from mechanical shock and dust.
The STR23SP delivers the reliability and precision required for secure power distribution and highly customizable fault prevention in commercial electrical networks.
