Merlin Gerin

Merlin Gerin

In 1920, Paul-Louis Merlin and Gaston Gerin created the Merlin Gerin Company and, in 1921, introduced the world's first range of high voltage, oil circuit breakers. Over the next 70 years, the strength of the MERLIN GERIN brand grew as the company expanded its operations worldwide.

Key MERLIN GERIN innovations include the pneumatically operated circuit breaker, the first 245,000 volt Hexabloc metal clad substation, the MULTI-9™ range of low voltage circuit breakers, the MASTERPACT® molded case circuit breaker, and the COMPACT™ NS circuit breaker. in 1992, Schneider Electric completed the acquisition of Merlin Gerin. Today, MERLIN GERIN remains a leading international brand in IEC type electrical circuit protection products.

Multi 9 GFP Ground-fault Protectors

For equipment ground-fault protection from 30 mA to 300 mA.Multi 9™ GFP Ground-fault Protectors help reduce downtime needed to repair equipment by detecting low-level ground faults before they cause damage. They automatically open the circuit when a ground fault detected between a phase and ground is greater than 30, 100, or 300 mA.
