The LELK121-1REC5-37275-50-G1- is a hydraulic-magnetic circuit breaker manufactured by Sensata-Airpax. These circuit breakers are designed to provide reliable overcurrent protection in various applications. Unlike thermal circuit breakers, hydraulic-magnetic breakers are less sensitive to ambient temperature changes, making them suitable for environments with fluctuating temperatures.

Applications

• Power distribution units (PDUs) in data centers.
• Uninterruptible power supplies (UPS)
• Marine and transportation equipment.
• Telecommunications equipment.
• Industrial control panels.

Features

• Hydraulic-Magnetic Technology: Provides stable and reliable overcurrent protection regardless of ambient temperature.
• Precise Trip Characteristics: Offers accurate and repeatable trip curves.
• Trip-Free Design: Prevents the breaker from being held closed during an overcurrent condition.
• Various Mounting Options: Available with different mounting configurations for versatile installation.
• RoHS Compliant: Meets Restriction of Hazardous Substances directives.

Benefits

• Reliable Protection: Ensures consistent and dependable overcurrent protection for sensitive equipment.
• Temperature Stability: Maintains accurate performance in varying temperature conditions.
• Prevents Equipment Damage: Protects valuable equipment from damage caused by overcurrents and short circuits.
• Long Lifespan: Designed for long-term reliability and minimal maintenance.
• Meets Industry Standards: Complies with relevant industry standards and regulations.

Additional Details

The specific current rating of the LELK121-1REC5-37275-50-G1- is 50 Amps, as indicated in the part number. The voltage rating and interrupting capacity should be verified in the product datasheet. These circuit breakers are typically constructed with a metallic housing and utilize high-quality internal components for robust performance. Resetting the breaker is achieved manually after the fault condition is cleared.
