- ln accordance with UL standard 508, suitable for installation in a protected environment and recognised as an industrial motor controller.
- Longer product life thanks to a free-swinging vane that draws a magnet within the solid metal switch body and activates a snap switch with a straightforward lever arm that doesn't need bellows, springs, or seals to break.
- Excellent resistance to chemicals and leak-proof body and valve made of robust, long-lasting polyphenylene sulphide.
