The 40 mm mushroom diameter and IP69K rating make this head suitable for a primary e-stop station on a washdown line; choose the illuminated ZB4BW643 variant instead when the station also needs a lit status indicator.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":54074982236443,"sku":"ZB4BS844","price":13.53,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-zb4bs844-emergency-stop-head-red.jpg?v=1790853580","url":"https:\/\/stoklink.com\/products\/schneider-electric-zb4bs844-harmony-xb4-emergency-stop-head","provider":"Stoklink","version":"1.0","type":"link"}
