Square D JDA36100 3 Pole 100 Amp 600V Circuit Breaker

The Square D JDA36100 is a 100-amp, 3-pole, 600V PowerPact J-Frame molded case circuit breaker for I-Line plug-in applications. It provides thermal-magnetic LI protection with a 14 kAIC interrupting rating at 600VAC and 18 kAIC at 480VAC. The JDA36100 is 80% rated for continuous loading, features dual-break rotating contacts, and includes an integral push-to-trip button for manual testing. I-Line plug-in construction allows for tool-free installation and removal in Square D I-Line panelboards and switchboards. It is UL 489 Listed, CSA Certified, and IEC 60947-2 compliant. The JDA36100 is commonly used as a feeder or main circuit breaker in commercial buildings, industrial distribution panels, and motor control centers, and serves as a modern replacement for legacy FA36100, FH36100, and HFD3100 I-Line breakers.
