Maasarent IS0FP-125 125A Four Pole Isolator Switch

Long Description

The IS0FP-125 125A Four Pole Isolator Switch is a heavy-duty electrical isolation device engineered to safely disconnect three-phase electrical circuits along with the neutral conductor during maintenance, servicing, and inspection. Designed for manual operation, it provides complete isolation of all four poles, ensuring maximum safety for personnel and connected equipment.

Featuring a 125A rated current and a Four Pole (FP) configuration, the IS0FP-125 simultaneously disconnects all three phases and the neutral conductor, making it suitable for high-capacity electrical installations such as industrial plants, manufacturing facilities, commercial buildings, generator systems, HVAC installations, motor control centers, and power distribution networks.

Manufactured using premium flame-retardant thermoplastic housing and precision-engineered contacts, the isolator delivers excellent insulation, low contact resistance, and long mechanical and electrical life. Its compact DIN rail-mounted design enables quick installation in distribution boards, switchgear panels, and electrical control cabinets. Four-pole isolators in this class are commonly manufactured in accordance with IEC 60947-3 and DIN rail installation practices.
