The MGP1003NAX is classified as obsolete by the manufacturer.
Rated 100 A and certified to BS EN 60947-3 for isolation, this 3-pole switch disconnector is intended for use as a visible-break isolator in panelboard feeders up to 250 A or 400/630 A panelboard mains. The utilisation categories AC-22A and AC-23A cover switching of mixed resistive and inductive loads, including motor loads within the rated current — AC-23A specifically permits switching of motors and other highly inductive loads. DC-22A and DC-23A extend the same capability to DC circuits. The short-time withstand current rating of 1600 A for 1 s (1800 A for 3 s, 690 A for 20 s) defines the fault-current duration the switch can carry without damage — critical for selective coordination in a distribution board. The rated short-circuit making capacity of 2.6 kA peak confirms it can close onto a fault without welding contacts. The IP40 enclosure protection keeps tools and fingers out but is not washdown-rated; the backplate mount is standard for panelboard integration. Electrical durability is specified at 35,000 cycles at 440 V at In/2 and 20,000 cycles at 440 V at In — this is the contact life under load, not the mechanical life of 50,000 cycles. The toggle control provides a clear visual contact-position indicator, confirming the isolation state required by BS EN 60947-3.
Certified to BS EN 60947-3, the standard for switch-disconnectors and fuse-combination units. Class II electrical shock protection means no protective earth connection is required on the device enclosure. The storage temperature range of -50 to 85 °C and operating range of -25 to 70 °C cover most panel environments.
