ABB S3N100 Three-Phase Molded Case Circuit Breaker

ABB S3N100 is a three‑pole molded‑case circuit breaker from ABB’s SACE Isomax family, rated for 100 A and up to 600 V AC (600 V / 500 V DC). It provides thermal‑magnetic protection with distinct long‑time and instantaneous trip elements and carries a short‑circuit current rating of 25 kA at 480 V and 35 kA at 415 V. This bolt‑on MCCB is designed for industrial power distribution, intended to protect three‑phase feeders in panels and switchboards where a fixed, non‑interchangeable trip is required. Typical applications include guarding motors, pumps, and other industrial loads in manufacturing and processing facilities, delivering reliable protection in low‑voltage electrical distributions.
