Siemens 52C301S Heavy Duty Pushbutton Control Station, Water and Oil Tight, 3 Command Points, Flush Black "FORWARD" Labeled Pushbutton, Flush Black "REVERSE" Labeled Pushbutton, Raised Red "STOP" Labeled Pushbutton, Momentary Operation, NEMA 4X Stainless Steel Protection, 1NO + 1NC Contact Types

Description

This Siemens 52C301S stainless steel enclosure with three pushbutton units have pushbutton actuators, holders, and contact blocks, and is suitable for use in wet or oily environments. The inscription plate for the top button reads "FORWARD", the inscription plate for the middle button reads "REVERSE", and the inscription plate for the bottom button reads "STOP". The pushbuttons actuate a normally open (NO) contact and a normally closed (NC) contact for momentary on/off operation. The contact block is rated at up to 600V and up to 7,200W power input. The enclosure meets the National Electrical Manufacturers Association (NEMA) type 4X standard for protection against dust and liquids. This stainless steel enclosure and pushbutton unit is suitable for use in applications such as controlling an electrical circuit in a wet or oily location in a manufacturing process control system.SpecificationsEnclosure typeStainless steel, "FORWARD", "REVERSE", and "STOP" inscription plates, wet and oily environmentsPushbutton typeThree pushbuttons (black, black, and red), holders, and contact blocks, momentary contactPower inputUp to 600V, up to 7,200W power inputContact type1 NO + 1 NCSpecification metNEMA type 4XPushbutton switches make or break electrical connections as part of a system that controls a process, such as a manufacturing line. Indicator lights with labels or color-coded caps are used to display the current state of a process, such as "completed." The pushbutton unit is composed of a pushbutton actuator for making or breaking electrical connections, a holder for securing the actuator to a control panel and for housing a light, and one or more contact blocks for connection to electrical wiring. Contacts within a contact block can be normally open (NO) or normally closed (NC), so that pressing the button starts or stops a process. Holders accommodate a range of control panel thicknesses and may include lamps to illuminate the button. Pushbutton actuator head types include mushroom, flat-surface, raised-surface, and key-operated, and may be illuminated, color-coded, and labeled. According to the requirements of an application, actuators may operate only as long as the button is held or they may lock into position when pushed and unlock when pulled or twisted. Pushbuttons and indicator lights are used in applications such as manufacturing process controls and as emergency shutoffs in industrial workplaces.Siemens manufactures electronic products for building automation, industrial drives, lighting, energy generation, medical equipment, and rail transportation.
