30 mm Start/Stop Control Station

This 30 mm wall-mounted control station provides a start/stop interface with two momentary push buttons coloured black and red. It is intended for industrial electrical control panels that require a compact NEMA 1 rated enclosure with IP20 protection. The unit suits operators who need a simple two-operator station without pilot lights.

Thermal noise and power draw

The station draws up to 5 A at 600 V AC or 24 V DC through its B600/P600 rated contacts, so power dissipation remains low in normal control-circuit operation. No active cooling is required and the plastic enclosure runs silently. Heat generation is negligible for the intended momentary duty cycles.

Build quality and mounting

The grey plastic enclosure measures 2.19 in high, 2.06 in wide and 3.69 in deep with a 1/2 in to 3/4 in NPT hub for conduit entry. Contacts are configured as 1NO/1NC with no mechanical interlock between the two operators. Builders who need a metal enclosure, a mechanical interlock or additional pilot lights cannot use this station.

Questions about this item

How do I mount the 30 mm control station and what is the common wiring mistake?

Mount it on a wall using the 1/2 in to 3/4 in NPT hub for conduit entry. The frequent error is exceeding the contact rating of 5A at 600V AC or 24V DC when connecting the 1NO/1NC circuits.

What part of the 30 mm start/stop station will need replacement first?

The momentary push button operators are the mechanical wear items. The black and red buttons endure repeated physical actuation, while the internal contacts are rated for the B600/P600 duty cycle.

At what point does the IP20 enclosure limit sustained operation?

The IP20 rating means the plastic enclosure is not protected against water ingress. Sustained use in wet or dusty environments will cause internal contact corrosion or shorting before the electrical ratings are reached.
