Description
Product Overview
The ABB ARCOL 0346 is a 3-pole, 46A, 690V AC thermal-magnetic circuit breaker engineered for industrial and commercial applications requiring robust overcurrent protection. Designed with ABB’s signature reliability, this breaker combines thermal overload and magnetic short-circuit protection to safeguard critical systems against damage from excessive currents, short circuits, and ground faults. Unlike motor control modules (e.g., ARCOL 0338/0339), the ARCOL 0346 focuses on circuit protection, making it ideal for power distribution panels, motor control centers (MCCs), and heavy machinery where precise fault interruption is essential.
Key components include a bimetallic strip for gradual overcurrent detection and a solenoid-driven magnetic trip mechanism for instantaneous short-circuit response. The module’s IP20-rated enclosure resists dust and solid particles, ensuring durability in harsh environments like manufacturing plants or outdoor substations. With a compact design optimized for DIN rail mounting, the ARCOL 0346 integrates seamlessly into existing switchgear or new installations, supporting auxiliary contacts and shunt trip coils for remote monitoring and control.
In automation systems, the ARCOL 0346 acts as a foundational layer of safety, preventing equipment failure and downtime. Its adjustable thermal trip settings (0.7–1.0x motor rated current) and fixed magnetic trip threshold balance flexibility with precision, while CE and UL 60947-2 certifications ensure compliance with global safety standards. By reducing maintenance costs through modular replaceable parts and hot-swap capabilities, the ARCOL 0346 delivers long-term value for industries ranging from water treatment to oil & gas.

Key Features and Advantages
Dual-Element Protection:
The ARCOL 0346 employs thermal-magnetic tripping technology to address both gradual overcurrents and sudden short circuits. The bimetallic strip responds to prolonged overloads by bending and triggering a mechanical trip, while the solenoid-based magnetic element interrupts high-energy faults within milliseconds. This dual-layer protection minimizes downtime and extends equipment lifespan in applications like pumps, compressors, and conveyor systems.
