  • Entry
  • Associated product(s)

The 3RV27 and 3RV28 circuit breaker range according to UL489 (previously only available in size S00) is now expanded by size S0. Two new versions with 20 A and 22 A respectively are offered.

Date for the Release for Delivery : 2012-04-27



Product description:
The new 3RV2721-4BD10 (20 A), 3RV2721-4CD10 (22 A), 3RV2821-4BD10 (20 A) and 3RV2821-4CD10 (22 A) circuit breakers according to UL489 complete the 3RV27 and 3RV28 range. The short-circuit breaking capacity amounts to 50 kA with 480 Y / 277 V. Thanks to their approvals according to IEC 60947-2 and UL489, these circuit breakers can be employed for short-circuit protection both in IEC and UL power distribution boards.

Differences compared with predecessor types:
The 3RV2721-4BD10, 3RV2721-4CD10 and 3RV2821-4BD10 versions are fully compatible with the 3RV1721-4BD10, 3RV1721-4CD10 and 3RV1821-4BD10 predecessor types. No predecessor product of 3RV2821-4CD10 (22 A) exists.

Ordering data:
3RV2721-4BD10: In = 20 A, 50 kA with 480 Y / 277 V
3RV2721-4CD10: In = 22 A, 50 kA with 480 Y / 277 V
3RV2821-4BD10: In = 20 A, 50 kA with 480 Y / 277 V

3RV2821-4CD10: In = 22 A, 50 kA with 480 Y / 277 V
