Highlights

Electrical engineering focused on operational continuity

The Pellizzari name is associated with a long tradition of Italian electromechanical engineering. That technical culture guides how today's protection range is selected and sized: dependable tripping under overload and short-circuit conditions, coordination between protection levels, operator safety and continuity of service in the most critical installations.

Overload protection

Thermal release protecting cables and loads against sustained overcurrents, preventing overheating and damage to the installation.

Short-circuit protection

Fast-acting magnetic release, with breaking capacities from 4 kA to 10 kA on miniature breakers and high performance on molded case and air breakers.

Industrial safety

1P to 4P configurations, fixed and withdrawable versions and operating accessories for safe running and risk-free maintenance.

Operational continuity

Selectivity between protection levels isolates only the faulty circuit and keeps the rest of the installation in service.

Three families, one complete protection range

From compact protection inside distribution boards to air circuit breakers for large plants: choose the right family and review the full technical data for every model.

Molded Case Circuit Breakers (MCCB)

Our molded case circuit breakers protect electrical circuits against overloads and short circuits. Robust and compact, they deliver reliable protection in industrial and commercial environments, ensuring safe and efficient operation. Range from 6 A to 1600 A in 2P, 3P and 4P versions.

Technical specs

Miniature Circuit Breakers (MCB)

A complete series of miniature circuit breakers, ideal for commercial installations, industrial panels and electrical distribution. Easy to install and maintain, they deliver a high level of circuit protection in a compact format, with breaking capacities from 4 kA to 10 kA and a DC version for photovoltaic systems.

Technical specs

Air Circuit Breakers (ACB)

For the most demanding and complex applications, air circuit breakers offer superior protection and optimal management of electrical loads. Engineered for heavy-duty industrial plants, generator sets, power distribution and critical infrastructures, where safety and reliability are essential. Range from 630 A to 6300 A, in fixed and withdrawable versions.
