THED113020WL **Black Face** - 20Amp Circuit Breaker

THED113020WL **Black Face** - 20Amp Circuit Breaker

When your dependable circuit protection is required in a commercial or industrial electrical system, the THED113020WL Black Face molded case circuit breaker provides the ratings and configuration needed to keep equipment and power distribution systems operating safely. Designed as a 20 amp, 1-pole THED series circuit breaker, this unit features a non-interchangeable thermal magnetic trip unit that responds to both overloads and short-circuit conditions, helping you to protect conductors and connected equipment from electrical faults.

With an impressive 65kA interrupting capacity at 277VAC, the THED113020WL is commonly found in applications where higher available fault currents demand a breaker capable of safely interrupting fault conditions. The included line-side and load-side lugs help you streamline installation, while the compact molded case design makes it well suited for switchboards, panel installations, distribution equipment, and other commercial or industrial power systems. For facilities maintaining existing THED-series equipment, this breaker delivers the form, fit, and function needed for a compatible replacement while preserving the original system design. Built for long service life, it remains a practical solution for electrical maintenance and repair projects.
