MPQ – Molded Case Circuit Breakers (MCCBs) for Industrial Power Distribution

MPQ refers to a comprehensive range of Molded Case Circuit Breakers (MCCBs), also known internationally as molded case switches or compact circuit breakers. These devices are designed to protect electrical circuits from overloads and short circuits, with ratings typically from 16A up to 1600A, in configurations such as 3P, 4P, and sometimes 2P. They feature adjustable thermal and magnetic trip units, high breaking capacities (up to 100kA at 415V AC), and are available with various accessories like shunt trips, undervoltage releases, and auxiliary contacts. The MPQ series ensures reliable performance in industrial environments, with options for fixed or plug-in mounting and compliance with IEC 60947-2 standards.

These MCCBs are essential in industrial power distribution systems, motor control centers, and main switchboards. They are widely used in manufacturing plants, commercial buildings, data centers, and renewable energy installations like solar farms and wind turbines. Their robust design makes them suitable for harsh environments, including those with high ambient temperatures or vibration. They also serve as main disconnects in electrical panels and as protection for large motors, transformers, and capacitor banks.

The MPQ category includes several subcategories such as fixed type MCCBs, withdrawable units, and electronic trip versions. Key article codes follow a pattern like MPQ-3P-100A, MPQ-4P-250A, or MPQ-ET-630A, where the suffix indicates poles, amperage, or trip type. For example, MPQ-3P-160A denotes a three-pole, 160A breaker. Other variants include MPQ-4P-400A for four-pole applications and MPQ-ET-800A for electronic trip models. These codes are standardized for easy identification and ordering.
