OML8N 1P+N RCCB for Single-Phase Distribution Boards
OML8N is a 1P+N residual current circuit breaker series for single-phase low-voltage AC installations. It is positioned for buyers who need RCCB protection in residential and commercial distribution boards where rated current, leakage sensitivity and wiring requirements should be confirmed before quotation.
Compared with multi-pole RCCB options, OML8N focuses on single-phase applications. OOHMAGE supports model selection, packaging discussion, technical document communication and export-order coordination according to confirmed order requirements.
Product Highlights
- 1P+N configuration: practical for standardized single-phase distribution board applications.
- Multiple rated currents: supports common 16A to 80A selection needs.
- Leakage sensitivity options: 30mA, 100mA and 300mA can be selected according to protection purpose.
- Clear installation parameters: wiring size, torque and operating conditions are available in the specification table.
Recommended Applications
Choose OML8N when the project is a single-phase AC distribution board and the buyer needs RCCB residual current protection. For three-phase applications, compare OML8 or OML8X.
