Why Choose the Lovato GLX421001 1000 A Fourth Pole Add-On?
The Lovato GLX421001 is a heavy-duty 1000 A fourth pole add-on designed for compatible Lovato GL series switch disconnectors. It provides an additional power pole for installations requiring four-pole switching and isolation, extending a compatible three-pole switch disconnector into a four-pole configuration.
As part of the Lovato GL switch disconnector accessory range, the fourth pole operates simultaneously with the main switch disconnector poles. This coordinated switching arrangement makes it suitable for three-phase systems where an additional conductor, typically the neutral, must be switched and isolated together with the phase conductors.
Designed for demanding industrial power applications, the 1000 A GL fourth pole platform provides a 1000 A conventional free-air thermal current rating, 1000 V rated insulation voltage and 12 kV rated impulse withstand voltage. Its robust high-current construction makes it suitable for switchboards, distribution systems and industrial equipment requiring dependable four-pole isolation.
