Panasonic EJ Relays - Manual (Page 2)

EJ (AEJ)
2. Specifications
Notes: *1 This value can change due to the switching frequency, environmental conditions and desired reliability level, therefore it is recommended to check this with the
actual load.
*2 The upper operation ambient temperature limit is the maximum temperature that can satisfy the coil temperature rise value.
Refer to 6. Conditions for operation, transport and storage mentioned in AMBIENT ENVIRONMENT .
*3 Condition: Nominal switching 100cycles, each cut off 800A
*4 When using a surge absorbing element for the relay coil drive circuit, please use with a surge absorbing element with a clamp voltage of 1.5 to 2.0 times the rated
operating voltage. When the coil is connected in parallel with a diode, resistor or capacitor, the release time will delay which might lead to degradation in shutoff
performance and electrical life.Contact terminals have polarity; therefore, please obey the wiring diagram when connecting contacts.The electrical load
performance value applies when a varistor is connected in parallel with the coil.
