Protistor® sizes 602 aR, 4200VDC

Mersen DC offers provide a very high performant protection for railway power and auxiliary circuits. Mersen DC Semiconductor fuse-links were developed to provide improved performance required by today's new DC equipment. These fuse-links are typically operated at more elevated temperature than other fuse type, have lower I²t to minimize damage to protected components on short circuits, lower watts loss and longer life.

HelioProtection® NH fuse-links 800VAC gR

Mersen NH fuse-links 800VAC was engineered and designed
specifically for photovotaic systems. gR types are full range breaking
capacity fuse-links and are used to protect cables and equipment.
They can interrupt any fault current, from overloads up to their
breaking capacity, and so can be used alone as protection. They are
the perfect solution of protection when used with DC/800VAC Solar
inverters.
This fuse range is offered along with Mersen 800VAC
Fuse-switch-disconnectors, for a complete fuse-system protection.
