£52.51
The Lovato P1MS3P040 is a compact three-pole modular switch disconnector designed for switching, disconnection and isolation of electrical power circuits. Part of the Lovato P1MS series, it provides a practical DIN rail mounted solution for industrial control panels, distribution boards and machine electrical systems.
Rated at 40 A, the P1MS3P040 is suitable for three-phase circuits with an IEC rated operational voltage of 400–440 V AC. Its AC-22A utilisation category allows it to switch suitable mixed resistive and inductive loads, while clear contact-status indication supports straightforward operation and maintenance.
The three-pole device occupies 3 DIN modules and mounts directly onto standard 35 mm DIN rail. With a rated insulation voltage of 1000 V, a 4 kV impulse withstand rating and compatibility with auxiliary-contact and padlockable accessories, it provides dependable isolation for modern industrial electrical systems.
Switch disconnectors such as the Lovato P1MS3P040 provide a defined means of switching and isolating electrical circuits for operation, servicing and maintenance. Its three mechanically linked poles enable simultaneous disconnection of all three phases in compatible three-phase electrical installations.
The P1MS series is designed for modular electrical panels and can also switch suitable resistive and inductive loads. Its compact DIN rail construction, clear contact indication and support for optional auxiliary-contact and padlocking accessories make the P1MS3P040 a versatile choice for industrial power distribution and machine-control systems.
