Susol TD-125NU - 50A, 3-Pole, Molded Case Circuit Breaker

Meet the Susol TD-125NU, a 50A, 3-Pole Molded Case Circuit Breaker designed to deliver reliable overcurrent protection in demanding electrical systems. Whether you’re wiring a distribution panel, a switchboard, or a motor control center, this breaker provides robust protection for three-phase loads with a compact, durable package.

• Three-pole protection for 3-phase systems—protects all phases simultaneously, making it ideal for motors, compressors, and three-phase feeders.
• 50A current rating—suitable for main feeders and branch-circuit protection in panelboards and MCCs without unnecessary tripping during normal inrush.
• Molded case enclosure—compact footprint and sturdy protection against dust and incidental impacts in industrial environments.
• Thermal-magnetic trip mechanism—provides fast fault isolation for short circuits and sustained overcurrents, helping prevent equipment damage and downtime.
• Versatile installation—designed for panelboards, switchboards, and control panels in industrial, commercial, and OEM applications; easy to integrate with standard mounting patterns.

Ideal for: technicians and engineers supporting motor control centers, distribution panels, and critical feeders where reliable protection and safe operation are non-negotiable. It’s also well-suited for OEM equipment where space is at a premium but protection cannot be compromised.

Key specifications

• Current rating: 50A
