ABB 81EA03E 81EA03A-E GJR2390333R1010 power protection relays

ABB 81EA03E 81EA03A-E GJR2390333R1010 power protection relays

ABB 81EA03E and 81EA03A-E GJR2390333R1010 are electric power protection relays produced by ABB Corporation, which are used to monitor electric motors or generators in power systems to protect them from damage in the event of faults or overloads. There are some differences between the two models, which will be explained in detail below:

Model: 81EA03E/81EA03A-E GJR2390333R1010

Working voltage: 24V DC/110-240V AC

Maximum current: 5A/1A

Operating temperature range: - 25 ° C to+70 ° C

Overload protection: When the motor or generator exceeds the rated current, 81EA03E/81EA03A-E will automatically disconnect the circuit to avoid damage to the motor or generator.

Short circuit protection: When a short circuit occurs in a circuit, 81EA03E/81EA03A-E will automatically disconnect the circuit to avoid damage to the motor or generator caused by short circuit current.

Under voltage protection: When the input voltage is lower than the minimum operating voltage, 81EA03E/81EA03A-E will automatically disconnect the circuit to protect the motor or generator from damage.

Overvoltage protection: When the input voltage is higher than the maximum operating voltage, 81EA03E/81EA03A-E will automatically disconnect the circuit to protect the motor or generator from damage.

In summary, ABB 81EA03E and 81EA03A-E GJR2390333R1010 are very reliable power protection relays that can be used to protect motors or generators in power systems and ensure their safe and reliable operation under various operating conditions.
