The 700-P400A4 industrial relay from Allen Bradley's Bulletin 700 series is tailored for robust applications demanding reliable operation. The relay operates at control voltages in the range of 460 to 480 volts with a frequency of 60 Hz. It is designed to handle up to 10 A of current through its four normally open contact configuration, making it effective for various switching tasks.

The contacts are composed of a silver-nickel material, which enhances conductivity and reduces wear, increasing the relay's longevity. It has a dielectric withstand voltage of 2,000 V AC, providing significant insulation against electrical surges. Notably, the relay has a quick pickup time of 10 milliseconds or less, ensuring it responds promptly to control signals.

The minimum switching current necessary for operation is 5 mA, which allows the relay to function adequately in low-power applications while maintaining a durable and robust performance profile. The IP20 rating indicates that this device is not fully sealed against dust and should be protected from direct water exposure.

Installation is simplified through open type DIN rail mounting, which enables easy integration into control panels. Recommended wire or conductor size for connections is 18 AWG, promoting secure electrical contact. Operationally, the relay functions effectively in temperatures as low as -20 °C, and within storage, it can withstand conditions down to -40 °C. This combination of features makes the 700-P400A4 an excellent choice for demanding industrial environments.
