TJJ426200WL **Older Style** - 200Amp Circuit Breaker

TJJ426200WL **Older Style** - 200 Amp Circuit Breaker

The TJJ426200WL molded case circuit breaker is designed for dependable circuit protection in your commercial and industrial electrical distribution systems requiring a 200 amp, 2-pole breaker configuration. Built as part of the trusted Q-Line family, this breaker features an older style black face design and a thermal magnetic trip unit with internal common trip functionality for coordinated protection against overloads and short circuits. Its cable-in/cable-out lug-lug configuration allows for straightforward installation in compatible switchgear and panelboard applications where maintaining proper fit and function is essential.

With interrupting capacities rated up to 42k A.I.C. at 240VAC, 30k A.I.C. at 480VAC, and 22k A.I.C. at 600VAC, the TJJ426200WL is well suited for demanding electrical environments that require reliable fault interruption capabilities. The breaker includes both line-side and load-side lugs, helping you to simplify field installation while supporting secure conductor terminations. HACR rating compatibility also makes it suitable for heating, air conditioning, and refrigeration equipment applications. Built with long-lasting molded case construction, this breaker is intended to provide consistent operation in properly maintained legacy electrical systems where exact compatibility matters.
