Description
ABB BSD0750: Product Overview
The ABB BSD0750 is a three-pole molded case circuit breaker (MCCB) from the BSD Series, designed for low-voltage power distribution systems requiring reliable circuit protection. As a core component in industrial and commercial electrical networks, it safeguards downstream equipment (motors, transformers, control panels) by detecting and interrupting abnormal currents (overloads, short circuits).
The BSD Series is engineered for versatility, featuring adjustable trip units that allow customization of protection settings to match specific load requirements. The BSD0750 is typically installed in switchboards, motor control centers (MCCs), or distribution boards, serving as the first line of defense against electrical faults. Its compact design and modular construction simplify integration into new or retrofit projects, aligning with global standards (IEC 60947-2) for safety and performance.

Typical Applications
The ABB BSD0750 is widely used in low-voltage power distribution systems:
-
Industrial Facilities: Protects motor circuits in manufacturing plants, conveyor systems, and HVAC units.
-
Commercial Buildings: Safeguards distribution boards in offices, hospitals, and shopping malls.
-
Infrastructure: Used in data centers, water treatment plants, and renewable energy substations.
-
Marine & Offshore: Suitable for shipboard electrical systems (with corrosion-resistant coatings).
Example: In a manufacturing plant, the BSD0750 protects a 750A motor control circuit, interrupting a 40kA short-circuit fault within 10ms to prevent damage to the motor and upstream transformer.
