The EZC100H2045 is a 2-pole EasyPact EZC100H thermal-magnetic circuit breaker rated 45 A at 40 °C (trip unit TM-D). The 45 A rating at 50 °C means the breaker is calibrated for continuous load at elevated panel temperatures — no derating guesswork for a warm enclosure. Breaking capacity spans 10 kA Icu at 125 V DC (1P) up to 100 kA Icu at 110–130 V AC, with 30 kA at 380–400 V AC and 20 kA at 440 V AC. The 2-pole configuration with front-front connections makes it a direct fit for single-phase or two-wire DC branch circuits in panelboards.
Deployment context
Fixed backplate mounting with a 25 mm connection pitch — this breaker is designed for distribution panels where the busbar spacing matches standard 25 mm centers. IP20 finger-safe terminals and IK07 impact resistance suit it for enclosed panel installation where accidental contact is a concern.
