Siemens 38 3AFS 1500 56 AC 2000A

The Siemens 38 3AFS 1500 56 AC 2000A is a high‑performance low‑voltage molded case circuit breaker engineered to provide dependable overcurrent protection, robust fault interruption, and reliable switching for industrial, commercial, and institutional electrical distribution systems. Manufactured by Siemens, this breaker is designed to safeguard power circuits against overloads, short circuits, and fault conditions while ensuring stable electrical distribution in demanding applications.

Rated at 2000 amperes with an alternating current (AC) voltage class typically up to industry standard levels (often 600 VAC depending on configuration), the 3AFS 1500 56 AC breaker is suited for high‑capacity circuits including feeders, switchboards, distribution panels, and motor control centers. Its solid construction and high interrupting rating help protect critical electrical infrastructure in manufacturing facilities, data centers, utilities, commercial buildings, and other heavy‑duty environments.

The breaker’s protection system typically incorporates thermal‑magnetic trip units (or optional electronic trip units), offering reliable detection of overloads and short‑circuit faults. These protective mechanisms help prevent equipment damage and minimize downtime by interrupting fault currents promptly and effectively. Configurable trip settings enable coordinated protection with upstream and downstream devices, improving system selectivity and enhancing overall electrical safety.

Constructed with a rugged molded case, tight mechanical tolerances, and durable internal components, the 3AFS 1500 56 AC breaker delivers consistent performance even under frequent operation and elevated electrical stress. Its secure connection interfaces and stable contact system support reliable installation and long‑term service life with minimal maintenance.

Optional accessories such as auxiliary contacts, shunt trips, and undervoltage releases can extend the breaker’s functionality, enabling remote operation, signaling, and integration with control or monitoring systems. This flexibility makes the breaker suitable for use in advanced power management and automated electrical environments.

Engineered to meet industry standards for safety and performance, the Siemens 38 3AFS 1500 56 AC 2000A molded case circuit breaker is a reliable solution for high‑current low‑voltage power distribution applications where robust protection and operational reliability are essential.
