Industrial E305318 Molded Case Circuit Breaker

The Altech E305318 is a two-pole, 20 A C20 miniature molded‑case circuit breaker (UL 489) in the L Series, designed for DIN‑rail mounting with a 10 kA interrupting capacity. This UL 489 listed device supports AC and DC applications in its family and uses C and D trip characteristics for reliable short‑circuit protection, making it suitable for motor control circuits, power supplies, and other distribution tasks in industrial panels. It accepts conductors from 14 AWG to 3 AWG (14–3 AWG: torque 17.7 in‑lb / 2.0 Nm; 18–16 AWG: torque 25 in‑lb / 2.8 Nm) and features front‑mounted terminals with IP20 protection at the front. Operating temperature ranges from -25°C to 60°C, with storage temperatures from -25°C to 75°C, and its mounting orientation is listed as in any plane on a DIN rail via top and bottom clips. The compact profile and DIN‑rail compatibility make the E305318 a practical choice for compact protection in distributed control panels where a 2‑pole, 20 A breaker with a 10 kA short‑circuit rating is required.
