104-D300EA24

The Allen Bradley 104-D300EA24 functions as a reversing contactor designed for substantial power applications. With an operational current rating of 300 Amperes, it is suitable for demanding environments. This contactor utilizes a coil voltage of 24 Volts DC, ensuring efficient operation across its applications. The main power contact configuration comprises three poles, while the auxiliary contact features a double-pole double-throw (DPDT) arrangement, enhancing versatility in control schemes.

Capable of handling operational voltages of 600 Volts AC, this contactor is ideal for 3-phase power circuits. It can operate effectively within a frequency range of 50 to 60 Hertz. A built-in mechanical interlock enhances safety during reversing operations, safeguarding against accidental activation. When it comes to maximum ratings, the contactor supports a fuse rating of up to 700 Amperes, ensuring the protection of connected circuits. Additionally, the short-circuit current rating reaches 18,000 A RMS symmetrical, which provides robust performance under fault conditions.

The maximum circuit breaker rating for this unit is 400 Amperes, an important specification for ensuring reliable operation in conjunction with upstream protective devices. The electrical life of the contactor is designed for high endurance usage under AC-3 applications, confirming its reliability in various operational contexts.
