Why Choose the IMO B10TCR3N20-30 RCBO?
The IMO B10TCR3N20-30 is a compact and dependable Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to protect three-phase electrical circuits against earth leakage, overload and short-circuit faults. As part of the professional IMO B10TCR circuit protection range, it combines residual current and overcurrent protection within a single DIN rail mounted device.
By integrating the functions of an RCCB and miniature circuit breaker, the B10TCR3N20-30 helps simplify electrical panel design and reduce the number of separate protective components required. The device monitors current balance while protecting connected cables and equipment against excessive current, providing comprehensive circuit protection for commercial and industrial installations.
Featuring a 20 A rated current, 30 mA residual operating current, Type AC protection, a C curve tripping characteristic and a 3 Pole + Neutral configuration, the IMO B10TCR3N20-30 is suitable for machinery, automation systems and three-phase distribution circuits.
Key Advantages
- Combined earth leakage, overload and short-circuit protection.
- 20 A rated current suitable for three-phase commercial and industrial circuits.
- 30 mA residual sensitivity provides additional protection against electric shock.
- Type AC protection detects alternating sinusoidal residual currents.
- C curve tripping characteristic accommodates moderate starting currents.
- Compact RCBO design helps conserve valuable DIN rail space.
Key Features
- IMO B10TCR RCBO series.
- 20 A rated current.
- 30 mA rated residual operating current.
- Type AC residual current characteristics.
- C curve overcurrent protection.
- 3 Pole + Neutral (3P+N) configuration.

Complete Protection for Three-Phase Circuits
An RCBO combines residual current detection with overload and short-circuit protection. When an earth leakage fault or excessive current is detected, the device disconnects the affected circuit, helping protect personnel, electrical wiring and connected equipment.
The IMO B10TCR3N20-30 provides an efficient alternative to installing separate RCCB and miniature circuit breaker devices. Its integrated construction can reduce wiring complexity, simplify fault identification and conserve space within distribution boards and control panels.
Typical Applications
- Three-phase industrial machinery.
- Commercial electrical distribution boards.
- Industrial control panels.
- Automation and production equipment.
- Motor and auxiliary power circuits.
- OEM machinery and electrical systems.
