Characteristics of the BE.. brake for EDR.. and EDRN.. explosion-protected motors
With regard to the general design and the basic functional principle, the BE.. brakes for EDR.. and EDRN.. explosion-protected motors are identical to the BE.. brakes and the BE.. safety brakes for the DR.., DRN.. and DR2.. standard motors.
The EDR.. and EDRN.. explosion-protected brakemotors are available for the following rule sets:
- ATEX: Equipment categories 3G and 3D
- IECEx: EPL protection level "Gc", "Dc"
- HazLoc-NA®: Class I Division 2 and Class II Division 2
They fulfill the following standards:
Rule set | EDR.. | EDRN.. |
|---|---|---|
ATEX | EN 60079-0 EN 60079-15 EN 60079-31 | EN 60079-0 EN 60079-7 EN 60079-31 |
IECEx | No brakemotor available | IEC 60079-0 IEC 60079-7 IEC 60079-31 |
HazLoc-NA® | EDR. < 0.75kW NEC500 C22.1 | EDRN ≥ 0.75 kW NEC500 C22.1 |
Depending on the individual requirements, the ex labels differ in terms of gas group, dust group, temperature class or the maximum surface temperature:
