Why Choose the IMO B10R4080-30 RCCB?
The IMO B10R4080-30 is a high-quality Residual Current Circuit Breaker (RCCB) designed to provide dependable protection against earth leakage faults in commercial, industrial and three-phase electrical installations. As part of the reliable IMO B10R RCCB range, this device offers effective protection against electric shock and insulation faults while helping maintain the safety and integrity of modern electrical systems. It is manufactured in accordance with IEC/EN 61008-1.
The RCCB continuously monitors the balance between live conductors and neutral, disconnecting the supply rapidly whenever residual current exceeds the rated operating value. Its robust construction, compact modular housing and DIN rail mounting make it suitable for new installations and electrical panel upgrades.
With a rated current of 80 A, 30 mA residual operating current, Type AC protection and a 3 Pole + Neutral (4 Pole) configuration, the IMO B10R4080-30 is ideal for protecting three-phase distribution systems, industrial machinery and commercial electrical installations.
