Siemens SPD69160NT Circuit Breaker

Siemens SPD69160NT is a three‑pole, 1,600 A molded‑case circuit breaker rated for up to 600 V, designed to protect high‑current feeders in industrial power distribution. It uses a Solid‑State Sensitrip III electronic trip unit (ETU) for precise overcurrent protection, offering long‑time and instantaneous trip functions to coordinate with upstream protections. Distributor listings consistently cite an interrupting capacity of 35 kA at 480 V for this model, and it is configured for bolt‑on mounting with lugs not included. As part of Siemens’ Sentron low‑voltage line, SPD69160NT is intended for use in panels, feeders, and motor control centers where reliable, high‑current protection is required in demanding industrial environments.
