The 595-B, which was created and manufactured by Allen-Bradley, is an auxiliary contact. In addition to having three poles and requiring 600 volts alternating current to function effectively, the 595-B has a rated current of 10 amperes and is classified as an auxiliary type of contact. A nonmetallic enclosure with 3R/12 rainproof, dust-tight, 4/4X watertight, and 4/4X watertight ratings is available in this 500 line NEMA contactors and starters series, which may be acquired with or without a control transformer.

This contract module is part of the Bulletin 509, series B, size 0 to 5 FNIP, and is part of the Bulletin 509. The Bulletin 500 line contactors and starters are intended to deliver great performance in a wide range of applications, including industrial, commercial, and other heavy operational interfaces. It is primarily intended for use with 500 line NEMA contactors and starters, among other things. This contractor chooses a eutectic alloy overload relay with a temperature range of –13 and +149 °F (–25 to +65 °C). This module is operational up to a height of 10,000 feet and then begins to degrade after reaching this altitude threshold.

Additionally, the 595-B is capable of executing AC3Starting of squirrel cage type motor types of machinery and switching off only after the motor has achieved maximum speed, as well as AC4Starting based squirrel cage type motors with inching and plugging duty, among other things. The 595-B from Bulletins 500 series contactors are 10 inches wide, 15 inches tall, and 6.39 inches deep in dimensions. Furthermore, this auxiliary contact is CSA authorized and has a configuration of 1 - N.C. This auxiliary contact is also UL-approved. This 595-B package has screw-style termination features.
