Product Description

This Siemens 3SB38 02-0DA3 plastic enclosure has two color-coded pushbutton actuators, holders, and contact blocks. The green pushbutton has a raised surface, actuates the normally open (NO) contact, and has a label with an "|" mark on the face of the enclosure. The red pushbutton has a raised surface, actuates the normally closed (NC) contact, and has a label with an "O" mark on the face of the enclosure. The contact blocks are rated at up to 400V and up to 10 amp. The gray enclosure is made of plastic for weather and corrosion resistance and has M20 threaded electrical conduit mounting holes at the top and bottom of the enclosure for electrical wiring. The unit has an operating temperature range of -25 to +70 degrees C and meets the Ingress Protection (IP) 65 standard for protection against dust and liquids. This enclosure and pushbutton unit conform to the European Committee for Electrotechnical Standardization (CENELEC) EN 60947-5-1 standard for control circuit devices and is suitable for use in applications such as manufacturing process control systems.

Pushbutton 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. The company, founded in 1847 and headquartered in Munich, Germany, meets International Standards Organization (ISO) standards 14001, 9001 and TS 16949.
